1Q40.57 - Cons. of Angular Momentum - Air Table

Code Number: 1Q40.57
Demo Title: Cons. of Angular Momentum - Air Table
Condition: Good
Principle: Action & Reaction
Area of Study: Mechanics
Equipment:
Air table and air source, heavy and light puck connected by aluminum bar, heavy incident puck.
Procedure:
Level the air table and make sure the two puck system floats freely. Try to hit the light mass puck at 90 degrees to the aluminum bar with the incident puck. Use video capture to watch the motion of both centers of mass.
A #57 drill can be used to clean the holes of the air table should they become plugged.
