2. Fundamental Principles

2.1. Conservation of Momentum

During a collision between the cue ball and an object ball, the total momentum before and after impact is conserved (assuming negligible energy loss to heat and sound). For a direct hit: [ m_1 v_1i = m_1 v_1f + m_2 v_2f ] where both balls have identical mass ( m ). In a perfectly elastic collision, the balls exchange momentum, leading to the classic “30° rule” for cut shots.

The "Throw" Effect: When two balls collide, they don't just bounce apart. Friction creates a "rubbing" force that can "throw" the object ball off its expected line by as much as six degrees.

The point where the cue tip strikes the ball determines its rotation, which significantly alters its path after impact. The Amazing World of Billiards Physics - Dr. Dave Pool Info This text is structured to mirror the layout

The Physics of Pocket Billiards: A Technical Primer

Abstract While pocket billiards is often perceived as a game of intuition and dexterity, it is fundamentally governed by the rigid laws of classical mechanics. A deep analysis of the sport reveals a complex interplay of kinematics, dynamics, and collision theory. This document explores the physical principles underlying ball motion, cushion recoil, and throw effects, providing a mathematical framework for predicting outcomes on the table.

: If you have an analytical mind or an engineering background, you will find the technical depth incredibly rewarding. It removes the "magic" and replaces it with predictable logic. Conservation of Momentum During a collision between the

4.2. Curved Shots (Masse)

Striking with extreme vertical axis tilt causes the ball to swerve in a parabolic curve due to the gyroscopic effect and cloth friction.
