# Elastic collision

###### What is it ?

An elastic collision is a type of collision in which the two colliding bodies deform elastically and retain their initial kinetic energy. This means that the two bodies bounce against each other without losing energy.
An example of elastic shock is the motion of two billiard balls colliding. If the two balls are in motion when they collide and bounce against each other without losing energy, the collision is elastic.
The formula for kinetic energy before and after an elastic shock can be written as follows:
Kinetic energy before = Kinetic energy after
Where "Kinetic energy before" is the kinetic energy of the two bodies before the impact, and "Kinetic energy after" is the kinetic energy of the two bodies after the impact.
It is important to note that in an elastic shock, kinetic energy is conserved, but potential energy and elastic energy can be converted into each other.
