(kÉnetÂ´iks), n the study of the forces that produce, arrest, or modify the motions of the body. Kinetics is the application of Newton's first and third laws of inertia to body dynamics. The reaction forces of the muscles contribute to the equilibrium and motion of the body.
Kinetic energy is the energy caused by the movement of the system, and potential energy is the energy the system can use. The total energy of the system is the sum of the two. The force is internal if the overall mechanical energy of the system doesn't change and is conserved. For example, when a ball is dropped from an elevation, gravity is pushing it to the ground.
