Here's why:

* Coefficient of Restitution: A golf ball has a much higher coefficient of restitution than a styrofoam ball. This means it can convert more of its kinetic energy into potential energy during a bounce.

* Density and Elasticity: Golf balls are made of dense, hard materials (like rubber or plastic) that are designed to be very elastic. This allows them to deform and spring back, transferring energy efficiently during impact. Styrofoam is much less dense and has a low elasticity. It absorbs more energy on impact, resulting in a less energetic rebound.

* Shape and Surface: The dimples on a golf ball also play a role. They create air pockets that reduce air resistance, which allows the ball to travel farther and maintain more energy for a higher bounce.

In short, the golf ball is built to bounce, while the styrofoam ball is designed to absorb energy.
