Section 06: Momentum and Impulse

Goal: To define momentum and explain its conservation in a closed system.

Objectives:

Students will be able to:

- define momentum.

- define impulse as a restatement of Newton’s second law

- relate impulse and momentum

-give examples of how both the size of the force and the length of the time interval affect the change in momentum.

- explain why impulses are greater when an object bounces than when the same object simply comes to a complete stop.

- state the law of conservation of momentum.

- distinguish between an elastic collision and an inelastic collision.

- give an example of how the vector nature of momentum affects the law of conservation of momentum.

-calculate the momentum of an object in one and two dimensions

-calculate impulse and relate it to changes in momentum

-use the conservation of momentum to calculate and explain the momentum of objects before and after collisions.

Labs:

1. Stationary elastic collision v1.0, free fall and projectile motion lab
