Elastic collision
A collision in which kinetic energy of the system is conserved is called elastic collision.
In the ideal case when no kinetic energy is lost, the collision is said to be perfectly elastic.
Example
when a hard ball is dropped onto a marble floor, it rebounds to very nearly the initial height. It loses negligible amount of energy in collision with the floor.
Inelastic collision
A collision in which kinetic energy of the system is not conserved , is called the inelastic collision.
Example
When tow tennis balls collide the then after collision , they rebound with velocities less than the velocities before, the inspect. During this process a portion of K.E is lost,partly due to friction as molecules in
