collisions in which kinetic energy is conserved.
A collision in which no kinetic energy is lost.
A collision in which objects rebound from each other with negligible loss of kinetic energy.
(See Collision, Elastic.)
An elastic collision is a collision in which the total kinetic energy of the colliding bodies after collision is equal to their total kinetic energy before collision. Elastic collisions occur only if there is no conversion of kinetic energy into other forms, as in the collision of atoms (Rutherford backscattering is one example).
