Linear Momentum
Chapter 7
Imagine a pool ball
That ball had mass and it had a velocity pointing in
one direction.
The combination of those two properties gives us a
new and important measurement.
Linear Momentum

Things to remember about graphs
Look at the axes first!
We have three types of graphs!

velocity versus time

Magnitude is the size of a measurement.
Some
our measurements also have direction.
