Behaviour of a Bouncing Ball
Cross, Rod
Physics Education, v50 n3 p335-341 May 2015
The bounce of a ball is a seemingly innocuous event that can be used to illustrate many aspects of elementary and even advanced mechanics. Both normal and oblique bounces on a rigid surface are considered in this article, emphasizing qualitative features of the bounce process. If the ball bounces at an oblique angle then it can slide throughout the bounce, or just at the start of the bounce, and may even slide backwards at the end of the bounce. A ball can also grip the surface after a short sliding phase, or it can grip right from the start. When the ball grips, static friction rather than sliding friction determines the rebound speed, spin and angle.
