THE SUBJECT OF THIS CARD IS:
WHY A HOLLOW RUBBER BALL BOUNCES
According to the U.S. Department of Energy, balls made of elastic materials such as rubber bounce
because the material stretches and deforms when they hit a surface and then reform back into their
original shapes, which releases energy into a kinetic form, causing the rubber ball to bounce.
The chemical make up of a ball determines how much the ball can be deformed, and therefore how much
of the original kinetic energy can be converted back to kinetic energy when the ball hits a surface. This is
called the ‘elasticity’ of the ball. In contrast an object that is inelastic would cause the energy to dissipate
by some other means. For example, a ball made of mud deforms when it hits a surface, but it can’t store
and reconvert the energy to kinetic energy, so it doesn’t bounce very high, doesn’t bounce at all or
releases its potential energy by destroying itself.
