Question

We dropped a golf ball from 100 cm in class. it bounced back to 60cm. why did it not return to the 100 cm mark?

Answer 1

Because the golf ball has (0 < e < 1) of elasticity therefore it did not experience the perfect elastic collision, the golf ball experienced an inelastic collision.

An elastic collision is a collision where there is no energy loss. It can be described by elasticity value. When an object has an elasticity value of 1, the speed of the object before the collision or after the collision is the same. The elasticity can be determined as

e = KEafter / KEbefore

where e is the elasticity of the object

when the object has elasticity 0 < e < 1, the object will partially lose the energy at collision.
