joule
/joohl, jowl/, n. Physics.
the SI unit of work or energy, equal to the work done by a force of one newton when its point of application moves through a distance of one meter in the direction of the force: equivalent to 107 ergs and one watt-second. Abbr.: J, j Also called newton-meter.
[1885-90; named after J. P. JOULE]

▪ unit of energy measurement
      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 (Joule, James Prescott), it equals 107 ergs (erg), or approximately 0.7377 foot-pounds. In electrical terms, the joule equals one watt-second—i.e., the energy released in one second by a current of one ampere through a resistance of one ohm.
