Mopping Up the Semester

Our last day of regular class was what I like to call a mopping-up day:

You can email me for electronic copies of the extra credit.

Momentum Practice Problems

Today we worked on our last set of problems for the semester, which is due next class:

Chapter 6 #59, 66, 74

You also received the practice test for the free response section of the final. Remember that the multiple choice section will have at least 8 problems and could cover anything from the entire semester. The best way to study for the multiple choice section is to review the multiple choice problems from previous tests and practice tests.

Here are the video solutions for the free response practice problems:

#1
#2
#3
#4

Conservation of Momentum in 2 Dimensions

Today we expanded our conservation of momentum problems into 2 dimensions.

Notes!

Here's another method of solving the practice problem in the notes:


We then started working on the the homework:

Chapter 6 (p. 193) #38, 49, 51

Impulse Due To a Variable Force

What is the change of momentum due to a force that is not constant? This was the question we attempted to answer today.

Notes!

Homework: Chapter 6 (p.191) #8, 15, 17, 68

Egg Drop Lab

Today you built a device to keep an egg from breaking when dropped off the visitors' bleachers. Here are the instructions that were on the board:

Your homework is Chapter 6 #12, 14, 19 + one paragraph explaining why your egg did or did not break (using momentum concepts) and how you could improve your design. Turning in this paragraph gets you participation points for the lab.

Impulse

So far we've only talked about situations where energy is conserved - that is, there are no outside forces. Today we talked about what happens when there are outside forces - the momentum changes! This change in momentum is called impulse.

Notes on Impulse

Video we watched

Next class you will be making a device to save an egg from breaking after a fall from the visitors' bleachers. You need to bring your own supplies if you can since mine are limited. It would also help if someone in your group brought an egg. After we test your device you will turn in a short explanation of why your egg did or did not survive using momentum concepts.

Homework for the weekend is Chapter 6 (p.191 ) Problems #9, 11, 13 + CONCEPTUAL Problem #12 (p.190)

Conservation of Momentum Problems

Today we just worked on various conservation of momentum problems. Whatever you didn't finish in class is homework and the whole thing is due tomorrow.

Chapter 6 (p.192) #21, 22, 25, 26, 27, 33, 37, 40, 41

I also checked your Ballistic Pendulum labs while you were working.

Finally, does anyone have an old egg or two? I want to do a demonstration tomorrow but I don't eat eggs so I don't have any on hand and I don't want to buy a whole container of eggs if I can avoid it. You might even get them back...maybe :)

EDIT: First period convinced me that we should do the egg drop project, so we're going to need 40 eggs total. If you bring an egg, write your name and period on it and you can use it for your project.

The goal will be to keep an egg from breaking when it is dropped from the visitors' bleachers. We'll have your modular day to build it, drop it, and write an explanation (using physics) about why your egg survived (or didn't). You can use anything you want except parachutes. The group whose egg survives with the lightest mass contraption (weighed with the egg inside) wins a prize (snack).

I have only limited supplies (pipe insulation, one bag of cotton balls, some quilt batting) so I ask that groups gather and bring their own supplies so that only the students that truly cannot afford it can use my stuff.

Ballistic Pendulum Lab

Today you completed the Ballistic Pendulum Lab in your lab notebook. You need a procedure, data, and answer (what is the launch velocity of the silver ball). It will be checked during class tomorrow.

Here is a running list of things people discovered about the lab apparatus (I'll update as needed):

• The mass of the pendulum bob is 86.2 g; don't try to measure that yourself
• Pull on the circular knob at the back to cock the launcher, not the stick-like knob near the front
• Flick the stick-like knob near the front of the launcher to launch the ball, not the circular knob at the back
• Don't use the third notch
• Cock the launcher and THEN load the ball
• If your table is uneven the launcher is less likely to work. Use the counters around the outside of the room
• The angle indicator is off on some of the launchers; check yours and compensate as needed

Conservation of Momentum

I didn't have access to my desktop at home this weekend, so I had to use a Chromebook and therefore Google Slides for our notes today (so no fancy animations):

Conservation of Momentum

You may have started working on your Ballistic Pendulum Lab, which you will be completing and is due on Wednesday. Your homework tonight is to be ready to take your data on Wednesday (whatever you need to complete to be ready).

Reminder: there are only a few weeks left in the semester; I would appreciate make-up work to be turned in sooner rather than later. Chapter 7 retake tests are also ready to go, although I will not have your tests ready to hand back to you until Wednesday (probably, though maybe earlier).

Momentum Intro

We squeezed in the intro to the next unit today:

Momentum Intro

Your homework is Chapter 6 (p.190) #1, 3, 6, 7

Have a great long weekend and see you in December!

Chapter 7 Test: Rotational Motion

Test today! No homework tonight.

Last Day to Review

Since we only had about 15 minutes to work on the practice test Friday, today was a work day. Your test is tomorrow. You can find the practice test and its solutions videos on Friday's blog entry.

Wrapping Up the Unit & Practice Exam

First we combined the Law of Universal Gravitation and circular motion to derive an interesting equation relating the radius of an orbit to period (period T = time for one cycle).

Then we talked briefly about tides and passed out the practice exam:

Chapter 7 Practice Exam

Solutions videos:
#1
#2
#3
#4
#5
#6
#7
#8

Monday will be a review day and Tuesday will be your test. Some people have expressed an interest in taking the test on Monday and having a workday on Tuesday instead due to the sheer number of other tests on Tuesday. That is fine - I will make an alternate version of the test for the early testers.

There will be no additional homework tonight; I would rather that you focus on the practice exam.

AP Practice Problems

Today I was absent, so you worked on and self- or peer-graded practice AP free response problems. These are purely for your practice and experience and we did not turn them in for credit. I recommend keeping these (and any others we do throughout the year) and using them to study for the AP exam in May.

Universal Gravitation

Today we used some fake data to derive the Law of Universal Gravitation. It ended up on the board:

Here is the fake data activity: Universal Gravitation Pseudo Lab

Homework was printed out on little strips. Here is an electronic copy: Homework 11/19. Don't forget to do the back.

Centripetal Force Lab: Finding g

Today you used the concept of centripetal force to validate the value of g near earth's surface. The pre-lab sort of leads you to a less accurate method of finding g because I originally wrote this for a conceptual class and they weren't familiar with linearization, but if you want to have a more accurate answer think about the practice AP problem from Friday.

You only need to turn in one paper per group. The group with the lowest percent error per period will get a slight amount of extra credit.

No homework tonight (except for finishing your lab).

Centripetal Force Practice

Today was a work day. This is what you did today:

• Finish last night's homework
• Complete AP Practice Problem 2009Bb1
• Self-grade AP Practice Problem 2009Bb1
• Start tonight's homework: Chapter 7 #65 & 74

Banked Curves

Today we derived the equation for the ideal speed of a car navigating a banked curve:

Banked Curves

Later we worked on Ch. 7 (p. 231) #52 & 62 which became homework if not finished in class. We will also have a little work time in class tomorrow if you still need help finishing.

Centrifugal Force

Today we talked about centrifugal force, which isn't a real force but rather a result of a rotating reference frame. This topic won't be tested, but it's pretty fun to think about and demonstrate.

Any leftover time was spent working on tonight's homework: Chapter 7 (p. 228) #20, 25, 26

Centripetal Acceleration and Force

Today we introduced centripetal acceleration and centripetal force. We'll be doing a lot more with these for the rest of the week.

Centripetal Acceleration and Force

Homework is Chapter 7 (p. 228) #17, 18, 22

Please remember that there is NO SCHOOL tomorrow for Veteran's Day.

Below is the work for an example problem in the notes.

Relationships Between Linear and Angular Quantities

Today we talked about how to go between linear and angular quantities.

Relationships Between Linear and Angular Quantities

We completed a worksheet in class with a ranking task on one side and a TIPER on the other.

Homework for the weekend is Ch. 7 (p. 227) #8, 9, 11

Angular Quantities

Today we introduced circular motion:

Angular Quantities

There was also a bit on the board to further explain radians; I'll try to get a picture of that up.

Homework is Chapter 7 (p. 227) #1, 2, 4

Chapter 5 Test

Today was your test! No homework!

Please remember to turn in that extremely long assignment that we've been working on since Friday.

Still Ch.5 Test Preparation

Today we were doing the same thing as Friday.

Chapter 5 Practice Test

Today we simply practiced chapter 5 problems and admired each other's costumes. I also handed out the practice test:

Chapter 5 Practice Exam

Here are videos with solutions to the practice test:

#1
#2
#3
#4
#5

Your real test will be next Wednesday (and shorter than normal).

On Monday/Tuesday we will continue to work on the problems we started today. They are actually due at the end of class Monday/Tuesday, but you should do all you can this weekend and then get help on the rest during class:

Ch. 5 #2, 10, 11, 18, 20, 24, 38, 44, 45, 47, 53, 66, 68, 92

Work Done by a Varying Force

This topic is very difficult to get into a Powerpoint, so unfortunately I don't have one. Instead we used the whiteboard:

What you really need to know is this:

The work done by a variable force acting on an object that undergoes a displacement is equal to the area under the graph of F_x vs. x. 

So, graph F_x vs. x and find the area under the graph to find the work done by that force.

We practiced this with a ranking task, then we started working on homework problems.

Homework is Chapter 5 (p. 163) Problems #59, 60, 61.

Power

Today's topic was power! There actually isn't much to say about power, so there were a few notes with several practice problems:

Power!

Any leftover time was spent starting homework or checking your labs from last week.

You have a test coming up next Wednesday.

Homework: Chapter 5 (p. 162) #50, 52, 56. Use watts, not horsepower on #50 part b.

Spring Potential Energy

Springs! Springs are awesome and useful. Today we briefly introduced springs (we'll be doing more with them later) and derived an expression for the potential energy stored in a spring.

Here are the notes: Spring Potential Energy

Note that we derived Hooke's Law  by graphing F vs. x, either by using a physical slotted mass/spring set or with the PhET simulation (depends on availability of materials).

We also used these awesome direct measurement videos by Peter Bohacek:
Cart on ramp with spring
Cart launched by spring

Your homework tonight is Chapter 5 (p.160) #35, 39, 67

Energy Practice Problems

I want to make sure everyone is on track with all of the energy stuff we've done so far before we add more, so today we simply worked together on various energy problems from the book. So the homework below really was classwork, with whatever you didn't finish as homework.

Homework: Chapter 5, Conceptual #5, 6, 10 AND Problems #1, 4, 6, 7, 23, 89 (starts on pg. 157)

Work

Today we talked about work:

Work!

There were a few things that didn't end up on the powerpoint, like some diagrams and a demonstration.

You homework tonight is Chapter 5, Problems 8, 9, 13, 16

AP Practice Problems

Today we peer-graded the practice AP exam problems that we turned in just before and after fall break. The grade you will actually receive for these will be for participation only - some for doing the problems in the first place, some for grading other students' work. The point was to get experience with the problems and the way the points are allocated.

You were also given one more practice AP problem. This one is pretty difficult, and if you didn't finish it in class it is homework.

Bouncing Ball Lab

Today was my last District training, so I was out again. You worked on a lab:

Bouncing Ball Lab

Your homework is a worksheet with a skater jumping some alligators on the front and a roller coaster on the back.

Conservation of Energy

Today we talked about the conservation of energy and used it to solve problems that we previously could only solve with kinematics.

Conservation of Energy

Homework is Chapter 5 Problems 25, 32, 33, 37

Energy

Today we talked about energy - specifically, the two main kinds of mechanical energy, kinetic and potential.

Mechanical Energy

We also got a new seating chart; please contact me if you need to move.

Homework: Just answer these two questions:

1.Which is running faster: an elephant or a mouse with the same kinetic energy? Explain.

2.A 2 kg book sits on a 1.5 meter high table. Emily says its Ug is 29.4 J and Ben says its Ug is zero. Who is correct? Explain.

PSAT

Most of you are taking the PSAT in the morning (seniors are at a special lecture) and I will only see periods 5 and 6 today. I figure everyone will be pretty burned out by then, so we will be watching BBC: Connections (1978) - Faith in Numbers. 

Ch.4 Test

Welcome back from break! The first 35 minutes of class will be your time for last minute review. The last 70 minutes of class we will take the chapter 4 test.

No homework except to rest up and study for the PSAT which most of you are taking on Wednesday.

Practice Exam

Today we got the practice exam for the chapter 4 test:

Ch. 4 Practice Exam

Videos of the solutions are below:

Problem #2
Problem #3
Problem #4
Problem #5
Problem #6
Problem #7
Problem #8

We also got two more old AP exam questions, due when we get back from break.

Practice - In an Elevator!

We did more practice problems today -specifically, what would a bathroom scale say in an accelerating elevator? We did one problem together:

Then we worked on a Ranking Task worksheet with the same kind of problems, and finally we worked on an old AP Physics problem (2003B1).

Ch.4 Additional Problems

More practice! We used class time today to work on more chapter 4 problems as well as making up some labs and such. Remember, end of quarter is Thursday!

Homework: Chapter 4 #69, 75, 78, 81

Friction Practice

Today we simply practiced problems involving friction. First we worked on the weekend's homework, then we started on tonight's homework.

I also checked your labs from Friday and talked about available extra credit. Remember that you must have everything turned in to be eligible for extra credit.

Homework tonight: Ch.4 # 47, 50, 57, 67

Static Friction Lab

First, some bellwork:


Then we completed the Static Friction Lab. If you missed class today you can do this lab at home with any rigid object that you can tip up (hardcover book, for example), a second object sitting on top of it, and a way to measure the angle of incline (protractor or ruler + trig).

Homework for the weekend is Ch. 4 CONCEPTUAL #4  and PROBLEMS #39, 41, 51

More on Friction!

Today we went more in depth with friction and practiced some friction problems.

Friction Problems

Homework is to finish any worksheets you didn't finish in class. There were three total.

Friction Intro

Today we are starting the topic of friction. This seems to be about how far we're getting today:

There is no homework.

Equilibrium Lab

Today you used force tables to explore equilibrium with the Equilibrium Lab. This lab is really meant to solidify our understanding of net force, so we're not doing anything truly new. The lab was done in your lab notebooks and your grade is based on participation, so there is nothing to turn in.

I also checked off your Newton's 2nd Law lab from last week since you already had your notebooks out.

Homework is Chapter 4 # 17, 20, 31

Ch.3 Test Overview

For today's shortened classes we got the chapter 3 tests back and went over them. If you got less than 80% you can retake it next week, but the maximum score you can get on the retake is 80%.

Homework tonight is Ch.4 #29 & 32

Inclined Planes

Today we continued looking at examples of Newton's Second Law problems - specifically, how do you deal with an inclined plane?

EDIT: Because of the epic fire alarm evacuation during 1st period, I will be posting videos of the inclined plane lecture and some homework problems. Check back here tonight for those videos.

Lecture: a block on a frictionless inclined plane (note that I made this for another class about a year ago so it may reference things that didn't happen to you).
Chapter 4 #27 (homework tonight)

Homework is Ch.4 #27 & 28

Solving Newton's 2nd Law Problems

Today we are practicing problems that use Newton's Second Law. I led you through one problem to show you the process, then we worked on steadily more complex problems to practice the process.

Solving Newton's Second Law Problems

I managed to remember to take a picture of the board after the example problem about the bird on the telephone line.

Homework: Ch.4 #19, 21, 25, 38

Newton's Second Law Lab

Sorry that I am out again on a modular day. This is the second of three all-day trainings I must attend, so only one more after this! I wanted to you to do a lab today, but without me there I was concerned about doing anything too complicated or dangerous, so unfortunately the lab is a "cookbook" type. I am not trying to insult you by giving such explicit instructions, honest!

Newton's Second Law Lab

Note that you are doing this entirely in your notebook and I will simply check it off later. You will not actually be turning anything in.

Homework tonight is Ch. 4, Problems 3, 10, 13, 16

Newton's Third Law

Today we first worked on some ranking tasks to practice Newton's Second Law. Then we talked about the Third (and last) Law:

Newton's Third Law

Homework is #7-10 on the Forces Non-Textbook Problems worksheet.

Newton's Second Law

Today we talked about free body diagrams, finding net force, Newton's Second Law, and weight. Notes are here:

Newton's Second Law

We also did a practice worksheet in class in which you found the net force from free body diagrams.

Homework tonight is #4-6 on the Force Non-Textbook Problems and Ch.4 Problem #2 out of the textbook.

Newton's First Law

Today we talked about Newton's First Law. There really isn't a whole lot to say, so the Powerpoint basically has a bellwork and states Newton's First Law:

An object at rest stays at rest and an object in motion stays in motion in a straight line unless acted upon by a net force.

There aren't any good problems in the book that deal with this, so I made some and handed them out:

Forces Non-Textbook Problems

Most of our homework this week will come from that paper. Tonight's homework is # 1 - 3.

Key Club Findraiser

Hello all. The UHS Key Club is holding a fundraiser to help fight ebola. When at least $10 is pledged toward a teacher, that teacher gets a pie in the face. I volunteered so if you want to see me get a pie in the face, go here:

https://fundly.com/uhs-key-club-help-fight-ebola

Chapter 3 Test and Forces Intro

Today we took the chapter 3 test for the first 75 minutes of the period. Later we started our new unit with an extremely short intro to forces:

Forces

No homework tonight.

Chapter 3 Review: Practice Test

Today we went over the practice test to review for your test first thing next week. Last time we did this I developed severe pain in my right shoulder from writing on the board all day (with arm straight up since I'm so short), so this time I made videos and showed those instead. We then answered specific questions when necessary.

Remember, points are given for showing your work as well as the final answer, so make sure to:

• show your equation BEFORE substituting numbers
• explicitly show what numbers are substituted where (including zeros)
• use proper units on answers

Here are the videos for the practice test free response problems:

#1: Find the time it takes a stone to reach the ground when it is thrown horizontally off a tower.

#2: Find the magnitude and direction of a vector given its components.

#3: Find maximum height and range of a projectile fired over flat ground.

#4: Find the range and final velocity of a diver.

#5: Find the velocity with which a ball rolls off a counter top given height of counter and range of ball.

#6: A centerfielder runs to catch a pop fly

In case you need it, you can download the practice test here.

Ch.3 Practice Exam

Today you had time to work on the Chapter 3 practice exam. Tomorrow we will go over it and your real test is first thing next week.

Ch.3 Additional Problems

First we went over one of last night's homework problems (class's choice), then we spent some time working on tonight's homework in pairs or groups so I could finish checking labs and helping individuals.

We will be having review activities for the rest of the week with a test first thing next week.

HW: Ch.3 #48, 52, 53, 57

General Relativity

Today we went over some of last night's homework and then talked about relative motion. There aren't really any notes except a little that made it onto the whiteboard:

And we ranked these pictures from greatest velocity of the person relative to the ground to least velocity of the person relative to the ground. The answer is on the left side of the board above.

Please remember that tomorrow before and after school is the last chance for test retakes. We are looking at another test next week.

Homework: Ch.3 #35d, 37, 40, 41

Projectile Motion Lab

Today we did a lab! Please bring your lab notebook next week so I can check it.

This is one of the launchers we used - many thanks to the University High School Foundation and Alumni Association for buying these this summer.

Homework for the weekend is Ch.3 #29, 30, 31, 32

Motion in 2 Dimensions

Motion in 2 Dimensions (Projectile Motion)

Here is the airplane problem worked out by two students:

I could not get my videos to embed in my Powerpoint - sorry! - so here are links to the ones we saw:
Mythbusters Bullet Drop
MIT Monkey Problem

Homework: Ch.3 #22, 23, 25, 27

Test and Retakes

Today you got your tests back and we went over them. Unfortunately I cannot put those solutions online so if you missed class please see me personally.

Retakes are before or after school Thursday and Friday, before school Tuesday, and before or after school next Wednesday. Note that after school Wednesday starts at 3:15 because of teacher collaboration 2:15-3:15.

Homework tonight is your Vector Lab that was passed out last class; see the previous blog entry for more information.

Vector Boot Camp

Today was all about vectors! How to add and subtract them graphically, break them into components and put them back together, and finally using components to add and subtract them.

Notes! (don't forget to play it as a slideshow!)

Since we don't really have computers in class, you need to do an online lab for homework (due THURSDAY): Vector Lab, which can be completed with the PhET simulation found here: Vector Addition. Note that you might not have the control needed to be perfect, but you can get close.

We also have book problems, but we already did several in class:
Ch. 3 Problems 1, 4, 6, 10, 16, 17, 18. These are due WEDNESDAY.

Chapter 1& 2 Test

Today was your test! You were allowed to use your blue sheet (although only my clean copies, not your personal blue sheet). No homework tonight. Have a great weekend!

Ch.1-2 Test Review

Today is our review day. Here is a study guide:

Ch. 1-2 Study Guide (cut into thirds)

We are also not turning in the homework that was due today. There is no way I could get it back to you before your test tomorrow and I want you to have it for studying. Instead, you continued working on it, checked it with each other, the key, and me, and I simply checked off that you did it.

No homework tonight, but your test is tomorrow and your Free Fall Lab write up is due tomorrow.

Lab Overview and HW Problems

Today we talked about two different ways to use your lab data to find the acceleration of gravity. Then we did #45 from your homework together, and the rest of the time was used to work on homework problems so that I could help individuals and groups.

HW: Ch. 2 Problems 45, 46, 48, 52, 53, 56, 57, 60, 61, 63

Free Fall Lab

Today we dropped things and measured their position and time to make a graph and calculate the acceleration of gravity! There are two versions of the lab:

Using LEDs and a long-exposure camera
Using a ball and slow motion video playback with timestamp

These only differ in how you get your data, not what you do with it.

Everyone needs to get data and basically do the whole lab in their notebooks, then the group picks one to use when writing up the final lab report (due Friday). We will be briefly talking about this lab on Wednesday in class.

I forgot to put tonight's homework in my sub plan on Monday, so I am combining tonight's homework with Wednesday's and making it all due Thursday:

Ch. 2 Problems 45, 46, 48, 52, 53, 56, 57, 60, 61, 63

Problem Solving for 1-D Kinematics

First we went through a method of solving 1-D kinematics equations:

Problem Solving Method

Then we spent the rest of the time working on conceptual problems individually or in groups.

Your homework is Ch. 2 Problems 34, 36, 37,40. Also try to bring either a camera that can take a long exposure or a camera that can take video and play it back frame by frame.

1-D Motion with Constant Acceleration

Today we derived the four main kinematics equations:

Equations! (Download and run as a slide show for it to work properly)

If we had time, we used a problem solving method to do some more problems together.

We are doing a lab next week for which a long exposure (~1.5 seconds) camera is needed. Please check your cameras/phones for that ability (is there an app for that?).

Homework is Ch. 2 Problems 26, 27, 28, 31.

Counselor Presentation

Today Ms. Allen talked to us about Student Rights and Responsibilities as well as what Juniors should be doing this year to prepare for graduation and college. There is no homework tonight, but please turn in last night's homework.

Acceleration and More Graphs

Today we talked about Friday's lab, acceleration, motion diagrams, and looked at more kinematics graphs. We also made some of our own with a Vernier motion detector.

We sort of went back and forth between Powerpoint, whiteboard, and practice problems, but here is the Powerpoint part:

Acceleration

Homework: Ch.2 #20, 22, 24. Also don't forget to turn in the motion diagrams ranking tasks we did in class.

Constant Velocity Lab!

Today you were given two cars, one fast and one slow. The goal was to have them hit a barrier at the same time if they start at the same time one meter apart. You could do any tests you wanted on the cars beforehand, but you only get one at a time and one try at the goal.

What you need to turn into me is one copy PER PERSON of the data you took and any calculations you made to get to the answer, plus your answer. That's it - no procedure or anything else.

Homework tonight is Ch. 2, Problems 13 and 17.

Graphs and Velocity

First we had a short quiz over metric conversions and right triangle trigonometry. Later we learned how you can use a graph of position vs. time to define and/or find average velocity and instantaneous velocity. I did not manage to get the graphs and diagrams for instantaneous velocity into the Powerpoint, so it went on the board.

Powerpoint: Using Graphs to Find Velocity
This picture of the board goes with the slide about instantaneous velocity:

Tomorrow we will be doing a lab, so bring your lab notebook.

Homework tonight: Ch. 2 (pg. 50) Problems 6, 8, 10.

Displacement, Speed, and Average Velocity

Today we began kinematics with position, displacement, average speed, and average velocity. Tomorrow there may be a short quiz over chapter 1 (conversions, significant figures, etc.)

Notes: 2.1 - 2.2 Displacement and Average Velocity
I used quite a few paths and overlapping animations in this one - please let me know if it does not work for you (miss.volkening@gmail.com).

Also, don't forget to turn in your group's Measurement Lab write-up.

Homework tonight is Chapter 2 (pg. 50) #1, 3, 5.

Measurement Lab

Today is our first lab! First we went over how to set up your lab notebook and a few particulars for this lab (see below) The Measurement Lab asks you to measure various objects in order to become familiar with certain tools (here is the caliper video we watched) and to review some volume and area equations. We will also be focusing on proper data taking techniques such as multiple trials and sharing the work among group members.

You should have enough time to complete and turn this in during class, but you can also turn it in next class.

 Homework tonight is Ch. 1, Problems 52, 53, 57 and AP Review #3 & 4.

Conversions and Coordinate Systems

Here are the notes for today: Conversion and Coordinates

I also drew a diagram for the coordinates part that looked like this:

Homework is at the end of chapter 1, Problems 15, 25, 33, 41, 43, 46, 49. They start on the bottom of page 21.

Welcome!

Welcome to a new school year and AP Physics 1! Today we passed out the syllabus and a letter for your parent/guardian (and you) to read AND SIGN:

Syllabus
Letter (with signature lines - due August 8th)

We also talked about the nature of science with the history of the model of the atom as an example, then jumped right into some notes:

Notes - Standard units, dimensional/unit analysis, and significant figures
And here is the Scale of the Universe page we looked at: Scale by Cary and Michael Huang

Homework tonight is at the back of chapter 1 and is due tomorrow:

—MC #1 & 4

—Conceptual #7

—Problems #9 & 10
