Momentum Test Practice

First you took a multiple choice cumulative test that I need for data. It won't hurt your grade.

The rest of the period (about 50 minutes) was work time. Your last unit test is on your finals day.

Here is the momentum test practice. The key is here. Here are some of the video solutions:

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 + CONCEPTUAL #11 (p.190). You will check this yourself - I don't want to grade it!

You might also have picked up a momentum test practice. The key is here. Here are some of the video solutions:

Impulse

So far we've only talked about situations where momentum 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

Homework is p.191 Problems #9, 11, 13 + CONCEPTUAL Problem #12 (p.190)

Momentum in 2 Dimensions

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

Notes!
Here is the solution to the first example problem:


Here is a solution to the second example problem:

Lab: Conservation of Momentum

Today you are completing Lab: Conservation of Momentum. Here is a picture on the board with some stuff. There happens to be some help with number 31 from the homework due today as well.



Homework is p.193 #36a, 37, 40

Collisions

Today we talked about collisions, which are really just another kind of momentum conservation problem.

Notes: Collisions

The PhET collision simulator is here.

Homework tonight is p. 192 #29, 31, 34a

You also need to complete the pre-lab for Lab: Momentum Conservation.

Conservation of Momentum

Today we had very few notes:

Notes: Conservation of Momentum

The rest of the period was yours to start your homework since it's a bit longer than yesterday's.

Homework: p. 192 #25, 26, 27

Rotational Motion Test

Ok, your test is today! We'll have about half an hour of work time first.
