Is erg a unit of heat?

The erg is a unit of energy equal to 10−7 joules (100 nJ). It originated in the centimetre–gram–second (CGS) system of units. It has the symbol erg. The erg is not an SI unit.

How is the SI unit of work related to the unit erg?

unit of work is erg. 1 erg = 1 dyne × 1 cm. = 105 dyne × 100 cm = 107 erg.

How is Joule related to erg?

Joule is the SI unit of energy while erg is the cgs unit of energy. Therefore, 1 Joule is equal to 107 erg.

What is the unit of work class 9?

joule
The unit of Work is Newton metre (Nm) or joule (J). 1 Joule is defined as the amount of work done by force of 1 N when displacement is 1 m. when both the force and the displacement are in the same direction, positive work is done.

What is work and SI unit?

S.I. unit of work is Joule. Work done when a force of 1 Newton displaces the body through a distance of 1 metre in the direction of force.

What is erg unit?

The erg (symbol, erg, i.e. the same as the unit) is the unit of energy in the cgs system, where one erg represents the work done when a force of one dyne is acting over a distance of one cm and is equivalent to 1 x 10-7 joules.

What is meant by erg unit?

erg, unit of energy or work in the centimetre-gram-second system of physical units used in physics; to lift a pound weight one foot requires 1.356 × 107 ergs. It equals the work done by a force of one dyne acting through a distance of one centimetre and is equal to 10-7 joule, the standard unit of work or energy.

Is erg an SI unit?

The erg is not an SI unit. Its name is derived from ergon (ἔργον), a Greek word meaning ‘work’ or ‘task’. An erg is the amount of work done by a force of one dyne exerted for a distance of one centimetre. In the CGS base units, it is equal to one gram centimetre-squared per second-squared (g⋅cm2/s2).

Is erg unit of work?

What is a erg equal to?

What do you understand by work done obtain the relation between joule and erg?

An erg is the amount of work done by applying a force of one dyne for a distance of one centimeter. In the CGS base units, it will be one gram centimeter-squared per second-squared. Whereas joule is the amount of work done by applying a force of one newton for a distance of one meter. Thus, 1joule=1newton×1m.

Is erg the smallest unit of energy?

The erg is the standard unit of energy in the centimeter-gram-second ( cgs ) or small-unit metric system . It is an amount of energy equivalent to that expended by a force of one dyne acting over a distance of one centimeter . This is a small unit of energy, equivalent to 0.0000001 (one ten-millionth) of a joule .

What is ERG 1?

erg 1. n. The centimeter-gram-second unit of energy or work equal to the work done by a force of one dyne acting over a distance of one centimeter.

What is the definition of Erg?

What is the unit used to measure kinetic energy?

The standard unit of kinetic energy is the joule, while the imperial unit of kinetic energy is the foot-pound.
