The joule (J) is the amount of work done by a force of one newton over a distance of one metre. It is also the energy dissipated as heat by an electric current of one ampere through a resistance of one ohm for one second.
The joule (symbol: J) is the basic SI unit of energy.A joule is equal to the kinetic energy of a kilogram mass moving at the speed of one meter per second (one joule is a kg⋅m 2 ⋅s −2).Alternatively, it is the amount of work done on an object when a force of one newton acts in the direction of the object's motion over a distance of one meter (1 joule equal 1 newton meter or N⋅m).

Joule Formula The Basic Formula for Work and Energy. The fundamental formula to calculate work or energy in Joules is given by: E=F×d. Where: E is the energy in Joules (J),; F is the force applied in newtons (N),; d is the distance over which the force is applied in meters (m).; Additional Formulas Involving Joules
A joule is a unit of energy in the SI system, named after James Prescott Joule. It measures the work done by a force of 1 newton over a distance of 1 metre, or the energy transferred by 1 watt in 1 second.
Joule is the SI unit of work or energy, equal to the work done by a force of one newton over one metre. Learn how joule relates to other forms of energy, such as heat, mechanical, electrical and chemical, and see examples of energy conversion.

Joule (J) is the SI unit of energy that measures the work done by a force. Learn how joule is used in physics, engineering, chemistry, electricity, mechanics, thermodynamics, and everyday life.
Joules are the standard unit used to measure the energy of waves. The energy of a wave is proportional to the square of its amplitude, and this energy per unit area is known as the wave's intensity, measured in joules per square meter (J/m^2). The total energy of a wave is the product of its intensity and the area over which it is measured ...
