Oblique and Head-On Elastic Collisions
Ng, Chiu-king
Physics Teacher, v46 n4 p240-241 Apr 2008
When a moving ball collides elastically with an identical, initially stationary ball, the incident ball will either come to rest (head-on collision; see Fig. 1) or will acquire a velocity that is perpendicular to that acquired by the target ball (oblique collision; see Fig. 2). These two possible outcomes are related in an interesting way, which we describe in this paper.
