MOMENTUM
HONORS PHYSICS

TEXTBOOK: Chapter 6, pages 149 - 167.

OBJECTIVES:

Define momentum and derive the formula for impulse and momentum from Newton's second law.
Explain why the forces exerted on an automobile driver in a collision are so much smaller when the driver wears a seatbelt than when he or she does not.
Write the mathematical expression of the law of conservation of momentum for two masses.
Define and isolated system and distinguish between external and internal forces as they relate to the law of conservation of momentum.
Solve one-dimensional problems relating to the law of conservation of momentum.
Solve two-dimensional problems relating to the law of conservation of momentum.
Distinguish between an elastic collision and an inelastic collision.
Explain why impulses are greater when an object bounces than when the same object comes to a complete stop.
