### Studying Suggestions for Unit 12 Quiz #1

Your next will be on Friday, March 21. The quiz will be a one-page quiz, covering both sides of a sheet of paper. The equations for momentum and the momentum change-impulse relation will be given. Other equations will have to be committed to memory. Other than a calculator, no other helps will be provided nor allowed. The quiz will be short and contain several multiple choice questions and a selection of 4-5 calculations. The quiz will primarily test your understanding of the basic concepts and problem-solving abilities (such as those used on the Internet Problems). Use of your packet, the Internet Problems and the online resources at Multimedia Physics Studios and The Physics Classroom should provide sufficient review. Students can expect the following concepts, skills, and problem-types to be assessed on this quiz:

1. Define momentum, identify its units, and make comparisons of the momenta of moving and non-moving objects.

|| Momentum ||

2. Define impulse, identify its units, relate impulse to momentum change and be able to analyze real-world collisions using the impulse-momentum change theorem; solve simple computational problems involving impulse and momentum change.

3. Use Newton's third law and logic to develop comparisons of the force, impulse, momentum change, velocity change and accceleration for the two objects involved in a collision or an explosion; state the importance of an isolated system in the analysis of a collision.

4. Use momentum conservation principles to analyze collisions and to solve complex computational problems.

5. Use momentum conservation principles and proportional reasoning to analyze perfectly inelastic collisions and to predict the outcome of a perfectly inelastic collision upon the velocity of coupled objects.
