  KE = 1/2 m v²
      where m = mass of the body
                v = instantaneous velocity of the body

Kinetic energy is a scalar quantity.

   KE = p² / (2 m)
             where  p = magnitude of the momentum

  change in the kinetic energy = work done on the body
               = change in potential energy
