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 = 1/2 *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. In its easiest terminology; that whatever the increase in speed, the kinetic energy will increase by three times the normal speed. The kinetic energy is dependent upon the square of the speed. Many things utilize kinetic energy. The United States Army uses kinetic energy on it THAAD missile so that the missile can use its hit-to-kill technology. Kinetic energy is most present in the human body as well. That is why many forms of holistic therapy and weight loss or diet and exercise programs are using the kinetic energy theory in order to produce the best ways for you to utilize your body's current weight for loosing weight. That is the basic principle behind programs like Pilates.
