Kinetic Energy
Kinetic energy is energy of motion. The kinetic energy of an object is the energy it possesses because it is moving. The kinetic energy of a point mass (m) is given by Kinetic energy. Kinetic energy is an expression of the fact that a moving object can go to work on anything it hits; it quantifies the amount of work that the object could do as a result of its motion. The total mechanical energy of an object is the sum of its kinetic energy and its potential energy. For an object of infinite size, this kinetic energy is called the translational kinetic energy of the mass to distinguish it from any rotational kinetic energy. The actual equation that stands for kinetic energy is like this: KE = ½ *M* V2. M stands for the mass of the object and V stand for the speed of the object. This equation reveals that the kinetic energy of an object is in direct proportion to the square of its speed. That means that for a two fold increase in speed, the kinetic energy will increase by a factor of four; for a threefold increase in speed, the kinetic energy will increase by a factor of nine; and for a fourfold increase in speed, the kinetic energy will increase by a factor of sixteen.
