ENERGY
energy, in physics, the capability for doing work. it should exist in potential, kinetic,
thermal, electrical, chemical, nuclear, or different numerous forms. There are, moreover,
heat and work—i.e., energy within the method of transfer from one body to another.
When it's been transferred, energy is usually selected consistent with its nature. Hence,
heat transferred may become thermal energy, whereas work done may surface in the
sort of mechanical energy.
All kinds of energy are related to motion. For example, any given body has K.E. if it's in
motion. A tensioned device reminiscent of a bow or spring, although at rest, has the
potential for making motion; it contains P.E. as a result of its configuration. Similarly,
energy is potential energy as a result of it results from the configuration of subatomic
particles within the nucleus of Associate in Nursing atom
Energy is often neither created nor destroyed however solely modified from one kind to
another. This principle is thought to be the conservation of energy or the primary law of
thermodynamics. For example, once a box slides down a hill, the P.E. that the box has
from being settled high on the slope is regenerated to K.E., energy of motion. Because
the box slows to a stop through friction, the kinetic energy from the box’s motion is
converted to thermal energy that heats the box and also the slope.
Energy is often regenerated from one type to a different in varied other ways. Usable
mechanical or current is, for instance, made by several forms of devices, as well as fuel-
burning heat engines, generators, batteries, fuel cells, and magnetohydrodynamic
systems.Within the metric system of Units (SI), energy is measured in joules. One joule
is adequate to the work done by a one-newton force acting over a one-meter distance.
Energy is treated in an exceedingly variety of articles. For the event of the thought of
energy and therefore the principle of energy conservation, see principles of physical
science; mechanics; thermodynamics; and conservation of energy. For the main
sources of energy and therefore the mechanisms by which the transition of energy from
one type to a different occurs, see coal; star energy; wind power; nuclear fission; oil
shale; petroleum; electromagnetism; and energy conversion.
