Abstract
This chapter describes kinetic energy. A body that is in motion possesses kinetic energy. The amount of kinetic energy in the body depends upon the mass and the velocity of the body. There are two forms of kinetic energy: translatory or linear; and rotational or angular. A stationary body of mass “m,” at position “A” has been considered. When acted upon by the force “F,” the body moves with uniform acceleration “a,” to position “B” in time “t.” At B, the body has a velocity “v.” The motion of the body has been illustrated by the velocity-time graph. When a body has linear and angular velocity, the total kinetic energy is the sum of the linear and angular kinetic energies.
