| joule (jl, joul) n. Abbr. J or j 1. The International System unit of electrical, mechanical, and thermal energy. 2. a. A unit of electrical energy equal to the work done when a current of one ampere is passed through a resistance of one ohm for one second. b. A unit of energy equal to the work done when a force of one newton acts through a distance of one meter. See Table at measurement. [After James Prescott Joule.] |
joule [dʒuːl]
n
(Mathematics & Measurements / Units) the derived SI unit of work or energy; the work done when the point of application of a force of 1 newton is displaced through a distance of 1 metre in the direction of the force. 1 joule is equivalent to 1 watt-second, 107 ergs, 0.2390 calories, or 0.738 foot-pound Symbol J
[named after James Prescott Joule (1818-89), English physicist]
