That's the Way the Ball Bounces! Stewart Prince and David Wang West Point Grey Academy Floor Location : J 1 P

We tested if temperature affects the bouciness of a golf ball. We thought if heating or cooling the balls affects their performance that it might make a difference in how far the balls can be hit off the tee and how far they bounce.

We controlled the drop height, the rebound surface and used 36 identical balls. Our independent variable was the golf ball temperature. The dependent variable was the bounce height of the balls that we recorded.

Our results show that temperature has an affect. In our research we learned that the elasticity of the rubber core is affected by temperature. The molecules in the rubber stretch and reform. This is called the Coeffecient of Restitution or COR of the molecules and it changes with different temperatures. We need to go back to do more testing to find the maximum COR and then see how much the COR affects your golf game.
