In an elastic collision, both kinetic energy and momentum are conserved. This means that the sum of the initial kinetic energies of the particles equals the sum of the final kinetic energies, and the sum of the initial momenta equals the sum of the final momenta. The collision between two billiard balls is an example of an elastic collision.
