WHAT IS KINETIC ENERGY

Kinetic energy is the energy which that moving objects have.
 Kinetic energy is  the energy of movement, because it refers to any object that is moving at that present time. This energy can be changed into other sorts of energy such as heat (if something hits with something soft and does not bounce), potential energy (if it is moving upwards and gets higher), or even light .However, heat, light, sound, mechanical energy, electrical, and other types of energy are also types of kinetic energy.
Kinetic Energy is equal to the mass of something times its velocity (or speed) times its velocity again, all times ½:
 kinetic\ energy = \frac{1}{2} \cdot mass \cdot velocity \cdot velocity
Meteors, bullets from a gun, a kicked football and all other moving objects have kinetic energy.
