WebThe SI unit of energy is Joule which is named after James Prescott Joule and the unit is same as the unit of power. The CGS unit of energy is erg. Visit BYJU'S to learn more.
WebEnergy is defined via work, so the SI unit of energy is the same as the unit of work – the joule (J), named in honour of James Prescott Joule and his experiments on the mechanical equivalent of heat. In slightly more fundamental terms, 1 joule is equal to 1 newton metre and, in terms of SI base units
WebThe joule (pronounced / ˈ dʒ uː l /, JOOL or / ˈ dʒ aʊ l / JOWL; symbol: J) is the unit of energy in the International System of Units (SI). It is equal to the amount of work done when a force of one newton displaces a mass through a distance of one metre in the direction of that force.
WebIn the International System of Units (SI), the unit of energy is the joule, named after Joule. It is a derived unit. It is equal to the energy expended (or work done) in applying a force of one newton through a distance of one metre.
