{Conservation of areas} (Astron.), the principle that the
radius vector drawn from a planet to the sun sweeps over
equal areas in equal times.

{Conservation of energy}, or {Conservation of force} (Mech.),
the principle that the total energy of any material system
is a quantity which can neither be increased nor
diminished by any action between the parts of the system,
though it may be transformed into any of the forms of
which energy is susceptible. --Clerk Maxwell.
[1913 Webster]


Energy \En"er*gy\, n.; pl. {Energies}. [F. ['e]nergie, LL.
energia, fr. Gr.?, fr. ? active; ? in ? work. See {In}, and

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.
[1913 Webster]

{Accumulation}, {Conservation}, {Correlation}, & {Degradation
of energy}, etc. (Physics) See under {Accumulation},

Syn: Force; power; potency; vigor; strength; spirit;
efficiency; resolution.
