Friction Practice

Today we are practicing some more complex friction problems. You have a problem set that is homework if you don't finish in class:

p. 118 #40, 42, 43, 78

We did #42 together in class:

Equilibrium Lab

Today we completed the Equilibrium Lab in your notebook, but first we went over the homework from Friday. You didn't actually turn any of it in because I am so far behind on grading.

While you were doing your Equilibrium Lab I checked your Newton's 2nd Law Labs from last week.

Homework is p. 116 #17,  24, 39

Friction

Today we started talking about friction:

Notes: Friction

We completed Friction TIPERs #1 in class; Friction TIPERs #2 and Friction TIPERs #3 are homework. Email miss.volkening@gmail.com for copies.

I'll be checking your lab next modular day while you do another lab.

Inclined Planes

Today we talked about how to deal with an inclined plane. This ended up on the whiteboard because there actually isn't much to it:

Once you have modified the free body diagram the problem is the same as the ones we were doing yesterday.

Hopefully you started your homework in class:

p. 117 #27 & 28

Solving Newton's 2nd Law Problems

Today we went through a method of solving word problems that involve Newton's 2nd Law:

Notes: Solving Newton's 2nd Law Problems

We may or may not have gotten to all of the examples, depending on the class.

You also got your last test back; please check to see that I added up your points correctly and entered your correct grade into Stats. Retakes are currently available.

Homework is p. 116 #19, 25, 38.

Newton's 2nd Law Lab

Today we first went over Forces TIPERs #2 as a class (keep in your notes). Then we worked on Newton's 2nd Law Lab. The diagram was up on the whiteboard:

Please have this completed in your lab notebook by Friday. You also have the worksheet Forces TIPERs #3 for homework tonight; email miss.volkening@gmail.com for a copy.

Half Day! Forces TIPERs.

Today periods were only 33 minutes long, so I dumped a bunch of TIPERs on you and we just worked. What you don't finish are homework:

Newton's 2nd Law Ranking Tasks
Forces TIPERs #1
Forces TIPERs #2

Email miss.volkening@gmail.com for a copies.

You also received a copy of the lab we are doing at the beginning of next week: Newton's 2nd Law Lab. Please read through this over the weekend.

Newton's Third Law

We have come to the last of Newton's three laws. There actually isn't a lot to say:

Notes: Newton's Third Law

We then worked on the worksheet Normal Force TIPERs (email miss.volkening@gmail.com for a copy). This is homework if you don't finish.

Official homework is #6-9 on the Forces Conceptual Problems Bank.

Tomorrow is half day so we will just have work time with more TIPERs.

Here are some sketches about normal force that made it up onto the board.

Newton's Second Law

Today we had a taste of Newton's Second Law:

Notes: Newton's Second Law

Homework:

p. 115 Problem #2
Force Conceptual Problem Bank #4 & 5

Forces and Newton's First Law

Today we started our forces unit with Newton's first law and free body diagrams:

Notes: Forces and Newton's First Law

We worked on a Net Force worksheet in class - it is homework if you didn't finish.

Homework is #1-3 on the Forces Conceptual Problems Bank.

2-D Kinematics Test

Test today!

No homework except for 2nd period. They need to fill out and return the forms I handed out.

If you didn't give me your lab notebook yesterday, do so today or send me a picture of your projectile motion lab at miss.volkening@gmail.com.

2-D Kinematics Practice Test

Today is your work day to study for the 2-D kinematics test tomorrow. Hopefully you picked up the practice test yesterday.

I also collected your lab notebooks so I can start grading your projectile motion lab. If your lab is in a notebook that you don't want to give up for a week (your notes are in there or something) take a picture (or pictures) and send it to me at miss.volkening@gmail.com.

Guest Speaker + Practice Test

Periods 1 and 2 spent the day in the auditorium listening to a guest speaker. Everyone else received their 2-D Kinematics Practice Test and went over last night's homework.

You will have one more work day for the practice test tomorrow, then your test in on Friday. Sometime by the end of Friday I will check your lab, so have it ready and your notebook present Thursday and Friday.

The electronic copy of the practice test is here, but it is missing the answers to number one. I will try to get a scan with those present posted here later tonight.

Projectile Motion Lab

Today we are completing the Projectile Motion Lab. Note that this is done completely in your lab notebook; you are not turning this in, but it will be checked.

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


Homework is the worksheet Projectile Motion TIPER #2 (email miss.volkening@gmail.com for a copy). We will be discussing the Evaluate Student Answers (ESA) problem tomorrow at the beginning of class.

Finishing your lab is also homework.

Projectile Motion Practice Problems

Today we just worked on some practice problems:

p. 81 #29, 30, 47, 48

There is no school on Monday. Tuesday is sequential and we will be doing the Projectile Motion Lab; bring your lab notebook.

Motion in 2 Dimensions

Motion in 2 Dimensions (Projectile Motion)

Here is the airplane problem worked out on the whiteboard:

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 is again in two parts:
A.) Worksheet Projectile Motion TIPER #1 (email miss.volkening@gmail.com for a copy)
B.)  Ch.3 (p. 80) #23, 25, 27

Relative Velocity

Today we passed back your tests and went over the last question. We then practiced another "evaluate student answers" question (this one was about vector components) but we did not turn it in.

Later we talked about relative velocity. There aren't a lot of notes:



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.) A worksheet with a relative velocity ranking task on the front and a vector component TIPER on the back (email miss.volkening@gmail.com for a copy)

B.) Ch.3 (p.82) #41 & 44
