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.
