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.
