The loss is usually described using coefficient of restitution. It provides instructions for making a "pith ball" to study static electric effects from different materials, and includes data on many common materials. The KE is dissipated by energy required to deform the ball, some of the KE is transformed into sound energy, and some of the KE is lost by frictional forces that generate heat (thermal energy). ”Long years have passed, child, I have never wed.
