Note: The kinetic energy of a body is the energy it has in
virtue of being in motion. It is measured by one half
of the product of the mass of each element of the body
multiplied by the square of the velocity of the
element, relative to some given body or point. The
available kinetic energy of a material system
unconnected with any other system is that energy which
is due to the motions of the parts of the system
relative to its center of mass. The potential energy of
a body or system is that energy which is not kinetic;
-- energy due to configuration. Kinetic energy is
sometimes called actual energy. Kinetic energy is
exemplified in the vis viva of moving bodies, in heat,
electric currents, etc.; potential energy, in a bent
spring, or a body suspended a given distance above the
earth and acted on by gravity.
