Energetic 2-Ball Bounces

Blast off! Harness the energy of two balls bouncing at once to send one flying in this simple physics activity.  Credit: George Retseck

How many ball sports can you name? How many of those have several balls at once in the game? Almost none, right? Games that do use several balls at a time most likely use balls of the same mass, volume and material. Would having two balls of different masses make a game very difficult? In this activity you will explore what might happen if you were to add a tennis ball to a basketball game or a tiny ping-pong ball to a tennis game or any other combination. Ready to be surprised? Try it out!
