Define elastic and inelastic collision
Elastic Collision
An elastic collision is one in which the system's kinetic energy is not lost as a result of the collision.It is a also known as Perfectly elastic collision
Above is the elastic collision definition
Inelastic Collision
A collision that is inelastic is one in which the kinetic energy is lost.
Thermal energy, acoustic energy, and material deformation are all converted from the lost kinetic energy.
