Explanation;Kinetic energy is the energy possessed by a body in motion. It is the work needed to accelerate a body of a given mass from rest to its stated velocity.Kinetic energy is directly proportional to the mass of the object and to the square of its velocity. It is given by the formula; K.E. = 1/2 m v2.Kinetic energy has units of kilograms-meters squared per second squared, where mass is in Kg and velocity is in m/s.
