The document provides an in-depth analysis of ball motion, including:

When a cue ball is struck hard with backspin, sliding friction continuously acts against the spin until the ball eventually transitions into a natural forward roll. The distance it takes for this transition to happen depends heavily on the slickness and quality of the cloth. 5. Advanced Mechanics: Jump Shots and Masse Shots the physics of pocket billiards pdf

For a completely sliding cue ball (one without topspin or backspin at the moment of impact), the collision physics are absolute. After hitting an object ball at an angle, the cue ball will always travel along a path exactly to the line of centers at impact. Deflecting the Tangent Line You can manipulate this 90-degree rule using vertical spin: The document provides an in-depth analysis of ball

Δθ = k × ω

If a cue ball is still sliding when it hits the object ball, it will follow the 90-degree tangent line perfectly. If it has transitioned into a natural roll, friction will cause the cue ball to curve forward, narrowing the angle to roughly 30 degrees (governed by ).

For a frictionless, non-spinning cue ball, the two balls will always separate at exactly a .

A rigorous would provide a table of throw angles versus cut angle and spin magnitude, derived from high-speed video experiments (e.g., studies by the Billiard University physics group).
