What makes billiard physics realistic?

Each collision transfers momentum along the line connecting ball centers. The perpendicular component is unchanged. With elasticity at 1.0 total kinetic energy is conserved across all collisions. Friction gradually slows the balls between hits.

Why do balls slow down between collisions?

Friction applies a drag force proportional to velocity. Without friction balls roll forever. Real pool tables have felt that creates friction and balls also lose energy to sound and heat on each collision. Set friction to zero to see perpetual motion.
