What causes a ball to be bouncy?

What causes a ball to be bouncy?

The force of the ball hitting the hard ground puts an equal force back onto the ball, causing it to bounce up. This happens because balls are made out of an elastic material like rubber, which means they can be dented or stretched and then return to their normal shape (think of what happens when you squeeze a balloon).

Is a bouncy ball rubber?

A bouncy ball or rubber ball is a spherical toy ball, usually fairly small, made of elastic material which allows it to bounce against hard surfaces.

Why do rubber balls bounce higher when heated?

This is because the gas molecules inside the ball expand as temperature increases. As the gas molecules expand, their energy increases and they bounce around faster inside the ball. That’s why higher pressure leads to a higher bounce of the ball.

Are rubber bouncy balls hollow?

What type of rubber are bouncy balls made from?

Why does a tennis ball bounce high?

Gravitation. The height to which the ball bounces is inversely proportional to the acceleration due to gravity at that place. Acceleration due to gravity on hills is less than that in plains, therefore the tennis ball bounces higher on hills.
