Question

Which material is likely to experience a nearly elastic collision?1) a water balloon2) an egg3) a steel ball bearing4) a stick of butter

Answer 1

Elastic collision:

In an elastic collision, the total kinetic energy of the system remains conserved.

In an elastic collision;

(a) Total kinetic energy is conserved.

(b) Total linear momentum is conserved.

(c) Total energy is conserved.

A steel ball-bearing is likely to experience a nearly elastic collision. Hence, option (3) is the correct choice.
