Tentative Outline for Test #3

Here are some topics that will likely come up on the test and some problems from the homework that you can focus on in preparation for the test.  Basically most of the problems are fair game for the test.  A few of them are similar in theme, so I have listed the types of problems that will be on the test first.

On Tuesday we will have a review.  Might come up with a practice test.  There will be approximately 10-12 problems on the test.  Depending on the combination/complexity of the problems.  If there are more problems then some of them will be more simple.
Linear/angular motion

Center of gravity

Torque

Moment of inertia

Rolling motion

Torque and balance

Spring and Hooke’s law

Compression & Young’s modulus

Cconservation of momentum and momentum problems

2D collission with momentum

 

Chapter 7 Problems:
1, 2, 9, 14, 21, 24, 27, 32, 35, 39, 42
Chapter 8 Problems:
6, 8, 9, 15, 19, 22, 23, 27, 28, 32, 41

Test #2 Solutions

Let me know if you have questions.

 

Test #2 Outline – Chapters 4, 5, 6

Approximately Nine Problems

1. Vector Addition/Subtraction
2. Units dealing with force
3. Tensions/weight/ropes
4. Object moving/friction
5. Forces and connected objects
6. Terminal Velocity
7. Angular velocity/acceleration
8. Gravity type problem
9. Rotational movement situation like ch. 6, 51)

Test #1 Solutions

Here are the solutions to the first test. I went over the cannon problem in class, but it’s here again. Learn how to do that, we’ll have a similar problem on the bonus quiz on Tuesday.

 

Physics 2A – First Test will be on Tuesday September 13

After some discussion, I decided to try breaking down the tests into smaller amounts of material.

The tests will be more frequent but cover less.

Test #1 will be on Tuesday September 13 at the beginning of lecture time.  Time allocated will probably be 40 minutes.

It will cover the first three chapters.  I will post a study guide for the test on this site.

Essentially, you’ll need to know the two kinematic equations and be able to do problems similar to the ones on the homework.

Physics 2A Homework Assignment #2

Chapter 2: Problems
2, 6, 11, 12, 19, 25, 27, 30, 34, 35, 38, 43, 53

 

Chapter two includes motion on a ramp – situations with skiiers, etc.

Projectile motion

And begins to get into circular motion.

Start them early and ask questions on Thursday!
