Coefficient Of Restitution: Why Certain Objects Are More Bouncy Than Others?

Coefficient of restitution: What is it? How is it related to the general bounciness of balls and other objects? Here's a quick, simple and basic explanation of the coefficient of restitution for kids and laymen.

Basketballs bounce a lot, but plastic balls don’t. Some objects are inherently bouncier than others. Why is that so? The answer lies in a property of the material which is known as the coefficient of restitution. The coefficient of restitution of a racquetball shall be different from the coefficient of restitution of a tennis ball. In this video, we give a layman explanation of what the coefficient of restitution is, and how does it make stuff bouncy.
