Ch 7 momentum notes
... momentum is a vector quantity ........has both magnitude and direction momentum can be canceled by equal and opposite momentum *if no net force or net impulse acts on a system, the momentum of that system cannot change -momentum of a system cannot change unless it is acted on by external forces -a s ...

Chapter 5 – Linking Forces to Momentum and Energy
... Answer to Essential Question 12.1: This estimated time is less than the actual time. The closer the block gets to the equilibrium position, the smaller the force that is exerted on it by the spring, and the smaller the magnitude of the block’s acceleration. Because the block generally has a smaller ...
