3 to 1 Collision Balls
# 1N30.20


Description: Two pendula on bifilar suspension have a mass differential of 3 to 1. Bring the smaller pendula back and release. When it collides with the larger pendula, they both recoil at the same rate to the same height. When they collide again, the large pendula stops while the small pendula recoils. The process repeats several times.
