## What is a joule in basic SI units?

In slightly more fundamental terms, 1 joule is equal to 1 newton metre and, in terms of SI base units. An energy unit that is used in atomic physics, particle physics and high energy physics is the electronvolt (eV).

The joule (symbol: J) is the SI unit of energy , or work. It is named in honor of the physicist James Prescott Joule ( 1818 – 1889 ).

The SI derived unit used to measure energy or work. One joule is equal to the energy used to accelerate a body with a mass of one kilogram using one newton of force over a distance of one meter. One joule is also equivalent to one watt-second.

SI unit. n. (Units) any of the units adopted for international use under the Système International d’Unités, now employed for all scientific and most technical purposes. There are seven fundamental units: the metre, kilogram, second, ampere, kelvin, candela, and mole; and two supplementary units: the radian and the steradian.

So, we can say that their units must be the same as the energy is what is lost or gained by doing work on an object or by the object. Note: The SI unit of both the work and energy is Joule. The dimension of both quantities is also the same because their units are the same. The dimension of work and energy is [ML2T−2].

Joule is the SI unit of work. 1 Joule is amount of work done when a force of 1 Newton displaces a body through a distance of 1m in the direction of the force applied.

Joule
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.

The amount of work done is equal to the energy used and both are measured in JOULES (J). It takes energy to lift a weight a certain distance, because you have to do work against the force of gravity.

1 Joule is amount of work done when a force of 1 Newton displaces a body through a distance of 1m in the direction of the force applied. Maths.

The SI unit of work is the joule (J), the same unit as for energy.

joule
The SI unit of energy/work is the joule (J), named for English physicist James Prescott Joule (1818 – 1889).

The joule (J) is the SI unit of energy and is named after English physicist James Prescott Joule (1818–1889). Then, in terms of SI base units a joule is equal to a kilogram times meter squared divided by a second squared (kg×m2s2) ( kg × m 2 s 2 ) .
