Correlation \Cor`re*la"tion\ (-l?"sh?n), n. [LL. correlatio; L.
cor- + relatio: cf. F. corr['e]lation. Cf. {Correlation}.]
Reciprocal relation; corresponding similarity or parallelism
of relation or law; capacity of being converted into, or of
giving place to, one another, under certain conditions; as,
the correlation of forces, or of zymotic diseases.

{Correlation of energy}, the relation to one another of
different forms of energy; -- usually having some
reference to the principle of conservation of energy. See
{Conservation of energy}, under {Conservation}.
{Correlation of forces}, the relation between the forces
which matter, endowed with various forms of energy, may
exert.

Energy \En"er*gy\, n.; pl. {Energies}. [F. ['e]nergie, LL.
energia, fr. Gr.?, fr. ? active; ? in + ? work. See {In}, and
{Work}.]
1. Internal or inherent power; capacity of acting, operating,
or producing an effect, whether exerted or not; as, men
possessing energies may suffer them to lie inactive.
[1913 Webster]
The great energies of nature are known to us only by
their effects. --Paley.
[1913 Webster]
2. Power efficiently and forcibly exerted; vigorous or
effectual operation; as, the energy of a magistrate.
[1913 Webster]
3. Strength of expression; force of utterance; power to
impress the mind and arouse the feelings; life; spirit; --
said of speech, language, words, style; as, a style full
of energy.
[1913 Webster]
4. (Physics) Capacity for performing work.
[1913 Webster]
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},
{Conservation}, {Correlation}, etc.
Syn: Force; power; potency; vigor; strength; spirit;
efficiency; resolution.

From WordNet (r) 3.0 (2006) [wn]:
correlation
n 1: a reciprocal relation between two or more things [syn:
{correlation}, {correlativity}]
2: a statistic representing how closely two variables co-vary;
it can vary from -1 (perfect negative correlation) through 0
(no correlation) to +1 (perfect positive correlation); "what
is the correlation between those two variables?" [syn:
{correlation coefficient}, {coefficient of correlation},
{correlation}]
3: a statistical relation between two or more variables such
that systematic changes in the value of one variable are
accompanied by systematic changes in the other [syn:
{correlation}, {correlational statistics}]
