Chapter 8: Momentum

Pace: 4 class periods

BIG IDEA
A moving object has a quantity of motion (momentum) that depends on its velocity and mass. In interactions between objects, the total momentum of the objects does not change. 
Standards Covered:
P3.5a Apply conservation of momentum to solve simple collision problems. 
8 Pretest and DifferentiationIf you score a 90% or above on this pretest on your first attempt you will not need to complete any of the practice for this unit and an accelerated assignment will be provided. The pretest is not open internet or buddy or book. This pretest will be timed and may only be completed in class.

8.4 Conservation of Momentum

Big Idea: The law of conservation of momentum states that, in the absence of an external force, the momentum of a system remains unchanged.
