Motion in 2 Dimensions

Motion in 2 Dimensions (Projectile Motion)

I could not get my videos to embed in my Powerpoint - sorry! - so here are links to the ones we saw:

Three Balls Roll Off a Table
Mythbusters Bullet Drop
MIT Monkey Problem

Homework: Projectile Motion TIPER #1 (email miss.volkening@gmail.com for a copy)

Relative Velocity

Bellwork is was a small half-sheet called ESA Practice: Vector Components. We used it to review yesterday's material and to look at the Evaluating Student Answers category of question, which will show up repeatedly in the future. You did not turn in this little paper.

Later we talked about relative velocity. There aren't a lot of notes; here is what ended up on the board first period:

Mythbusters did a pretty cool experiment showing the forward velocity of a truck cancelling out the backward velocity of a cannonball so that the velocity of the cannonball relative to the ground was zero: Mythbusters Frame of Reference.

Section 3.5 in the textbook also talks about this, albeit with a lot more math than we used.

Homework is in two parts tonight:

A.) Kinematics TIPERs #4 (email miss.volkening@gmail.com for a copy)
B.) p.82 #41 & 44

Please note that this means you will be turning in two different things tomorrow.

Vectors

Today we are learning all about vectors in general. This is needed because many, many quantities in physics are represented by vectors (velocity and acceleration for example).

Notes: Vectors (remember to run as a slideshow).

Homework tonight:

Chapter 3 (p. 78) #1, 17, 18

1-D Kinematics Test

Your 1-Dimensional Kinematics test was today. If you were not able to take it today, it would be best to take it before 1st period next Friday. You can still take it after that, but you would have to take another version and I cannot guarantee you would then have a third version available as a retake.

Your Free Fall Lab is due on your next modular day. Please either hand-write it or, if you type it anyway, submit it to Turnitin.com. Email miss.volkening@gmail.com with your period number and I will send you the class code and class key.

Practice Test

Today was your last day to work on your practice test. I also took a few minutes to go over how to maximize points earned on my tests:



Here is an abridged answer key for the practice test:

Free Fall Lab Part 2

Now that I am back in town, it's time to finish your labs. So today we all went outside so you could drop balls off of the bleachers. We took data for three different heights outside, and since you all used the same three heights you can share data between groups to get more trials.

You final lab is due on your next modular day. The lab sheet has specifics on what you need to turn in.

You have no additional homework tonight, but remember that your test is on Friday.

Free Fall Lab Part 1 + Practice Test

You had a sub today, so you started taking data for your free fall lab, but only inside the classroom. We will go outside on Wednesday to drop the balls off of the bleachers, so bring a sun hat and sunglasses. Here is the lab in case you lost your sheet: Free Fall Lab.

When you had 4-5 different heights done, you moved on to working on the practice test. You do not need to turn this in, but you should make sure you can complete the whole thing with only your equation sheet for reference. You will have more time to work on this and ask me questions on Thursday.

Also, DO NOT LOOK DIRECTLY AT THE SOLAR ECLIPSE.

Problem Solving Method

Today we went over a method for solving word problems, then talked briefly about free fall. I also went over the lab you'll be starting when I am gone on Monday/Tuesday.

Notes: Problem Solving and Free Fall (run as a slideshow)

Homework:
p. 52 #37, 43, 46, 51, 54

1-D Motion Part 2

Today we continued learning and using kinematic equations.

Notes: 1-D Motion with Constant Acceleration Part 2

Homework may have been started in class:

p. 51 #29
p. 52 #31 & 45

1-D Motion Part 1

Today and tomorrow we are learning the kinematics equations that we'll be using for the rest of the year. There's a lot of content to get through, plus practice, so I have split this into two different days.

Today's Notes: 1-D Motion with Constant Acceleration Part 1

You probably had time to start your homework in class as well:

P. 49 #1, 2, 6
P. 52 #33
P. 55A #2 (If your book does not have this page, email me at miss.volkening@gmail.com and I'll send you a picture of that page)

Acceleration and Graphs of Motion

During bellwork we talked about your Constant Velocity labs (due tomorrow) and also made our first velocity vs. time graph. Then we defined acceleration, looked at how it affects motion diagrams, and made acceleration vs. time graphs out of velocity vs. time graphs. Finally we went backwards, finding change in velocity from acceleration vs. time graphs and change in position from velocity vs. time graphs.

Whew. Lots of graphs.

Here is the Powerpoint: Acceleration and Graphs of Motion

Homework is Kinematics TIPERs #3. It is full of copyrighted material, so email miss.volkening@gmail.com if you need a copy.

Below are the answers for the bellwork.

Constant Velocity Lab

Today you worked on the Constant Velocity Lab! Your individual write-up is due next Wednesday. Remember, you can only use one car at a time, so no trial and error!

You may hand write your paper, or you can type it and submit it to Turnitin.com. Email miss.volkening@gmail.com with your period and I will send you the class code and class key.

Using Graphs to Find Velocity

Today we used graphs to find both average velocity and instantaneous velocity. The notes about instantaneous velocity included a graph on the whiteboard.

Notes (Powerpoint): Using Graphs to Find Velocity
On the board:

Homework tonight is the half-sheet HW: Velocity. It contains copyrighted material, however, so I cannot post it on the internet. If you need a copy, email miss.volkening@gmail.com and I can send you a PDF scan.

We also received the instructions for the lab we're doing tomorrow, Constant Velocity Lab. You will have all day tomorrow to work on this.

Displacement, Average Speed, and Average Velocity

Today we started our actual physics content with position, displacement, average speed, and average velocity.

Notes: Displacement, Average Speed, and Average Velocity

You may have started your homework at the end of class. Please finish it and turn it in tomorrow: Kinematics TIPERS #1. Email miss.volkening@gmail.com if you need a copy.

Mini Labs!

We spent today taking three sets of data:

• The time for a ball to drop 1.5 meters from rest
• The distance a projectile travels before hitting the ground
• The mass of one washer

The goal was to have these things in your lab notebook for each set of data:

• A short procedure
• organized data
• a description of one random and one systematic error and how they affected your data (how did they affect precision, accuracy, or both)

The idea behind today was for you to work through some common data gathering mistakes. To that end, I wandered around asking (extremely) leading questions while you were taking data in an attempt to steer you in the right direction. You will have a grade for today, but if you were here and participating you received 100%.

If I did not have a safety contract from you, you were not allowed to interact with lab supplies. 

Measurement and Error

Today we talked about standard units of measurement, why we have significant figures, and the two types of errors.

Notes: Measurement and Error

This weekend please get a lab notebook, preferably with graph paper pages.

Next week we’ll be doing little labs to get familiar with equipment. For homework, think of ways to measure the following that would reduce errors the most and write a short procedure:

• Time for a ball to fall a certain distance
• Distance a projectile travels
• mass of small objects

Welcome!

Welcome to AP Physics 1 with Ms. Volkening! Today we went over the class policies and procedures, passed out all the paperwork, etc.

Here is the Powerpoint used in class: Day One

You received copies of your syllabus, a letter for your parent/guardian, a safety contract, and an equation sheet.

You need to bring back the safety contract signed by you and your parent/guardian.

Please also take this survey to help me with preferred names and seats:
