Solution

Kinetic space Energy space equals space 1 half cross times Mass cross times Velocity squared space space space space space space space space space space space space space space space space space space space space space space space space space space equals space 1 half MV squared
When a body is not moving, velocity, V is zero. Hence kinetic energy is also zero.

Therefore, only moving bodies possess kinetic energy.
