In reality, collisions are not perfectly elastic. The coefficient of restitution ($e$) measures the "bounciness" of the collision. For high-quality phenolic resin billiard balls, $e \approx 0.95$ to $0.98$. This slight loss of energy results in the angle between the two balls being slightly less than 90 degrees, a phenomenon known as the "inelastic correction."

When the cue ball strikes an object ball at an angle, they separate at exactly 90 degrees (for a perfectly elastic, frictionless collision). In reality, due to friction during contact, the angle is slightly less than 90° (typically 85–88°). the physics of pocket billiards pdf

Abstract Pocket billiards (pool) is a game often perceived as one of intuition and dexterity. However, at its core, it is a pristine application of classical Newtonian mechanics, rigid body dynamics, and friction physics. This article explores the fundamental physical principles governing the motion of billiard balls, including elastic collisions, the vector dynamics of spin, and the coefficient of friction between the ball and the cloth. If the cue ball has sidespin (english) when

If the cue ball has sidespin (english) when it strikes the object ball, the frictional force at the contact point pushes the object ball slightly offline.

The player manipulates the point of impact to control spin:
