erg

(ûrg), unit of workwork,
in physics and mechanics, transfer of energy by a force acting to displace a body. Work is equal to the product of the force and the distance through which it produces movement.
or energyenergy,
in physics, the ability or capacity to do work or to produce change. Forms of energy include heat, light, sound, electricity, and chemical energy. Energy and work are measured in the same units—foot-pounds, joules, ergs, or some other, depending on the system of

Erg

a unit of work or energy in the centimeter-gram-second system. The symbol is erg. One erg is equal to the work done by a force of 1 dyne when the point at which the force is applied is displaced 1 cm in the direction of the force. One erg equals 10–7 joule = 6.24 × 1011 electron volts.

Erg

a general name for sand masses in the deserts of North Africa. Ergs are usually confined to low-lying parts of the relief. The largest are the Grand Erg Occidental and the Grand Erg Oriental. The relief consists mainly of dunes, which rise to 200–300 m in height, stretching in the direction of the prevailing trade winds.

(geography)
A large expanse of the earth's surface that is covered with sand, generally blown by wind into dune formations.
(physics)
A unit of energy or work in the centimeter-gram-second system of units, equal to the work done by a force of magnitude of 1 dyne when the point at which the force is applied is displaced 1 centimeter in the direction of the force. Also known as dyne centimeter (dyne-cm).

erg

A unit of energy in the CGS system. It is equal to .0000001 joule in the MKS system. See CGS system.
