Elastic collision

Collision in which kinetic energy is conserved

In physics, an elastic collision is a collision process between two physical objects in which the total kinetic energy of the two bodies remains the same before and after the collision. In an ideal, perfectly elastic collision, there is no net conversion of kinetic energy into other forms of energy such as heat, sound, or potential energy. During the collision of small objects, kinetic energy is first converted to potential energy associated with a repulsive or attractive force between the particles (when the particles move against this force, i.e.
