Final Practice

We don't have enough time for a unit test on momentum, so instead your final will consist of multiple choice problems from the whole semester and free response problems only from the momentum unit.

Here is the practice test for the free response section of the final. 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:

Momentum in Two 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 (photo from 2014):




Homework: Ch.6 (p. 193) # 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 + CONCEPTUAL #11 (p.190)

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.

Ballistic Pendulum Lab

Today you are completing your Ballistic Pendulum Lab. Turn in the prelab for a grade and show me your completed lab in your notebook for participation points.

Collisions

Today we continue using conservation of momentum to solve problems, this time involving collisions.

Notes: Collisions

The PhET collision simulator is here.

Conservation of Momentum

We only had 20-30 minutes today because a counselor came in to talk to you about course selections for next year. I am not sure how much your class got through.
