'''''Important Setup Notes:'''''

 * N/A

'''Setup and Procedure:'''

 1. Flip the power switches located on the bottom of the pucks to the on position and place the units on a table or the floor.
 1. "AA" Batteries are stored in refrigerator.

'''Cautions, Warnings, or Safety Concerns:'''

 * N/A

'''Discussion:'''

Use the two air pucks to model inelastic collisions between equal masses at zero friction.
