Code Number: 1N30.21
Demo Title: Elastic & Inelastic Collision of Solids - Balls
Condition: Good
Principle: Conservation of Linear Momentum, Coefficient of Restitution
Area of Study: Mechanics
Equipment:
Steel plate, Set of steel balls, Ping-Pong ball, Super ball, Handball, and Impulse Demo.
Procedure:
The happy/sad ball set has one ball that bounces much like a super ball and one ball that bounces very little.
Combinations of the other balls will give different elastic coefficients.
