Friction between the two balls during impact can "pull" the object ball slightly off its geometric path. Advanced players compensate for this by aiming a fraction of a millimeter away from the true contact point. 5. The Coefficient of Restitution
Known as "English," sidespin doesn't change the path of the cue ball much until it hits a cushion. At that point, the rotation interacts with the rail, changing the angle of reflection (the Law of Reflection ). 4. Throw and Deflection: The Hidden Variables the physics of pocket billiards pdf
When you hit the ball with sidespin, the cue ball actually displaces slightly in the opposite direction of the strike. Friction between the two balls during impact can
At its heart, billiards is a game of energy transfer. When the cue ball strikes an object ball, the path the object ball takes is determined by the . The Coefficient of Restitution Known as "English," sidespin
