Collisions Demo: Billiard Balls

This is a demonstration of planar collisions of billiard balls. The force of collision (the normal force of one ball on the other) is the only important force during the collision, and all other forces can be ignored.

This demonstration was created at Utah State University by Professor Boyd F. Edwards, assisted by James Coburn (demonstration specialist), David Evans (videography), and Rebecca Whitney (closed captions), with support from Jan Sojka, Physics Department Head, and Robert Wagner, Executive Vice Provost and Dean of Academic and Instructional Services.

This is great. Simple, straight to the point and informative. Thanks.

The concepts explained are so simple to me now, thanks a ton for this deonstration

Many people actually think they can transfer side spin from cue ball to object ball

Sir if a ball in motion collide with a ball at rest. Will the balls move in opposite direction?
