Answer:
Kinetic Energy is the energy possesed by a moving body.
Explanation:
Kinetic Energy = 1/2mv^2. You can also write Kinetic Energy = p^2/2m where p=mv, i.e., linear momentum.
In relativity, it is different. there kinetic energy is gamma times mc^2, where gamma = 1/(1-v^2/c^2)^1/2

Explanation:
Expression for K.E - KINETIC ENERGY-K.E = 1/2 mv2. "Energy posses by a body by virtue of its motion is referred to as 'Kinetic Energy'". Kinetic energy depends upon the mass and velocity of body. If velocity is zero then K.E. of body will also be zero.
