The mathematics of a bouncing ball

by Stephanie Chasteen on December 5, 2008

tt_icon_170Have you ever really listened to the sound of a bouncing ball? There’s some elegant mathematics to be had in this simple thing. In this episode of my Science Teaching Tips podcast, staff educator and physicist Tom Humphrey takes us to the most perfect bouncing ball I’ve ever seen (or heard) — an exhibit at the Exploratorium. The platform the ball is bouncing on is a huge chunk of heavy marble, bolted to the floor. (What does that have to do with anything? Think about conservation of energy and momentum). You hear some surprising things as a small metal ball bounces on that surface. Even without the exhibit, this is something you can do with your students, and integrate science and math into your curriculum.
