PURPOSE: Demonstrate collisions of pucks on an air table in rooms not accessible by the large air table.

DESCRIPTION: This small air table can be readily moved on a small rolling cart into all physics classrooms. Both elastic and inelastic collisions can be demonstrated using a variety of puck masses. Velcro collars are used to create inelastic collisions.

SUGGESTIONS: The larger air table is only available in rooms 1410,1412, and 0405 because it will not fit through a standard door.

REFERENCES: (PIRA unknown.)

EQUIPMENT: Small air table on cart, variety of pucks and velcro collars.

SETUP TIME: 5 min.
