Description: This demonstration shows different coefficients of restitution using the happy and sad balls.
- Happy and Sad balls
- Show that the balls are very similar, in shape, feel, and weight.
- Drop the happy ball. Note that it bounces up high.
- Drop the sad ball. Note that it does not bounce much.
- Explain that this is due to different coefficients of restitution, where a coefficient closer to 1 corresponds to a greater restitution and a higher bounce.
