Question

What is an elastic collision?

Answer 1

Elastic collision is the collision where there occurs no loss in net kinetic energy as the result of collision.

Explanation:

Total Kinetic energy before the collision= Total kinetic energy after the collision

For example,

Bouncing back of a ball from the floor is an example of elastic collision.

Some other examples are:-
`=>`collision between atoms
`=>`collision of billiard balls
`=>`balls in the Newton's cradle... etc.
