Chapter 8: Momentum

Pace: 4 class periods
Checkpoint:  25 November

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 Differentiation

If 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.
