coefficient of restitution

Mathematics

A parameter associated with the behaviour of two bodies during a collision. Suppose that two billiard balls are travelling in the same straight line and have velocities u₁ and u₂ before the collision and velocities v₁ and v₂ after the collision. If the coefficient of restitution is e, then

$v_{2} - v_{1} = - e (u_{2} - u_{1}) .$

This formula is Newton’s law of restitution. The coefficient of restitution always satisfies 0 ≤ e ≤ 1. When e = 0, the balls remain in contact after the perfectly inelastic collision. When e = 1, the collision is perfectly elastic: there is no loss of kinetic energy.
