ELASTIC COLLISION Definition & Meaning

elastic collision

noun

Mechanics.

a collision in which the total kinetic energy of the colliding bodies or particles is the same after the collision as it was before ( inelastic collision ).

elastic collision

/ ĭ-��ă��′��ĭ�� /

A collision between bodies in which the total kinetic energy of the bodies is conserved. In a perfectly elastic collision, no energy is dissipated as heat energy internal to the bodies, and none is spent on permanently deforming the bodies or radiated away in some other fashion. Elastic collisions, such as the collision of a rubber ball on a hard surface, result in the reflection or “bouncing” of bodies away from each other.

When, however, we spoke of the conservation of force, in the case of elastic collision, we meant neither a pull nor a push, which, as just indicated, might be exerted upon inert matter, but we meant force invested in motion — the vis viva, as it is called, of the colliding masses.
