When a cue ball strikes an object ball at an angle rather than dead center, the physics follow a predictable geometric pattern known as the .

Knowing this rule allows players to predict exactly where the cue ball will go, which is essential for position play and avoiding scratches. 3. The Power of Spin: Draw, Follow, and English

The cue ball transfers all of its kinetic energy to the object ball. The cue ball stops dead in its tracks (a "stun shot"). the physics of pocket billiards pdf

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.

When the moving cue ball strikes a stationary object ball, it transfers its kinetic energy. In a perfectly elastic collision between two balls of equal mass, the total momentum before the crash equals the total momentum after the crash. The 90-Degree Rule (The Tangent Line) When a cue ball strikes an object ball

If you are studying the topic, these are the fundamental areas covered in these documents: Ball-Ball Collisions

Because the balls are of equal mass and possess a high coefficient of restitution (elasticity), they behave nearly ideally as perfectly elastic bodies in collision scenarios. The felt cloth provides a friction coefficient ($\mu$) that is low enough to allow sustained travel but high enough to generate the specific rotational behaviors (spin) that define the game.
