Joules Definition

Joule is the name of England physicist, his name James Prescott Joule (1818-1889)

The joule is the derived unit of energy in the International System of Units.
It is defined as:

One joule is the amount of energy required to perform the following actions:

The work done by a force of one Newton travelling through a distance of one meter;

The work required to move an electric charge of one coulomb through an electrical potential difference of one volt; or one coulomb volt, with the symbol C·V;

The work done to produce power of one watt continuously for one second; or one watt second (compare kilowatt hour), with the symbol W·s. Thus a kilowatt hour is 3,600,000 joules or 3.6 megajoules;

The kinetic energy of a 2 kg mass moving at a velocity of 1 m/s. The energy is linear in the mass but quadratic in the velocity, being given by E = ½mv²;
