A joule ( / ˈdʒaʊl / or sometimes / ˈdʒuːl /) is a unit in the SI system. It measures energy; usually in scientific or electrical appliances . It is named after James Prescott Joule. A joule refers to the amount of energy transferred to an object when a force of 1 newton is applied on it over a distance of 1 metre (1J = 1N × 1m).
joule, unit of work or energy in the International System of Units (SI); it is equal to the work done by a force of one newton acting through one metre. Named in honour of the English physicist James Prescott Joule, it equals 10 7 ergs, or approximately 0.7377 foot-pounds.

A joule is the SI base unit for energy. It is equal to 1kg⋅m2 s2 1 k g ⋅ m 2 s 2. [1] In physical terms, lifting an apple one meter takes 1 joule of energy. This should not be confused with a watt which is a unit of power and a rate of how fast energy is used.
May 11, 2018 · joule Symbol J. The SI unit of work and energy equal to the work done when the point of application of a force of one newton moves, in the direction of the force, a distance of one metre. 1 joule = 10 7 ergs = 0.2388 calorie. It is named after James Prescott Joule (1818–89).
