Maths/ Model of moving balls

This is a model of three balls in space that collide into each other and the walls.

It uses conservation of momentum to calculate paths by working in coordinates parallel and perpendicular to the line joining the centres at the moment of collision.

Turn gravity off to simulate snooker balls viewed from above!

It also features some unrealistic tweaks when the balls sit on top of each other.
