Code Number: 1Q40.60
Demo Title: Cons. of Angular Momentum - Ball or Cylinder Paper Pull
Condition: Good
Principle: Conservation of Angular Momentum
Area of Study: Mechanics
Equipment:
Basketball, Rubber Ball, Metal Ball, Ring, Hollow Cylinder, Axel with Low Mass Wheels, and Construction Paper.
Procedure:
Place the desired object on the center of the construction paper. Quickly pull the paper out from under the object. The object will slide but also begin to spin as the paper is being pulled out from under it, but will stop dead when it comes off the paper and onto the table.
