Study Guide: Momentum

Assignments:

• Read chapter 6, sections 12 - 16

• Work problems page 138: 1- 6, 10, 18; due Tues. Nov 14

For the test over momentum you should know:

• The units of momentum and impulse.

• What two things impulse is equal to.
• When momentum is conserved (linear and angular), and when energy is conserved.
• What is meant by elastic and inelastic collisions, how are they recognized, how do they differ?
• How forces, time, and impulse compare for each object involved in a collision.
• How the vector property of momentum affects 1 dimensional collisions
• How bouncing affects impulse or change in momentum.
• How angular speed depends on rotational inertia and angular momentum.
• How the force of a collision can be reduced.
• What the ultimate test of an elastic collision is.
• How to calculate final velocity in an inelastic collision.
• How to calculate the force in a collision.
• How to calculate the impulse from a force vs. time graph.
