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.
