The '''joule''' ({{IPAc-en|ˈ|dʒ|uː|l}} or whiles {{IPAc-en|ˈ|dʒ|aʊ|l}}), seembol '''J''', is a [[SI derived unit|derived unit]] o [[energy]], [[Wirk (pheesics)|wirk]], or amoont o [[heat]] in the [[Internaitional Seestem o Units]].<ref>{{SIbrochure8th|page=120}}</ref> It is equal tae the energy expendit (or wirk duin) in applyin a [[force]] o ane [[Newton (unit)|newton]] throu a distance o ane [[metre]] (1 newton metre or N·m), or in passin an electric  [[current (electricity)|current]] o ane [[ampere]] throu a [[resistance (electricity)|resistance]] o ane [[ohm]] for ane seicont.  It is named efter the Inglis pheesicist [[James Prescott Joule]] (1818–1889).<ref>[http://education.yahoo.com/reference/dictionary/entry/joule American Heritage Dictionary of the English Language] {{Webarchive|url=https://web.archive.org/web/20120618091004/http://education.yahoo.com/reference/dictionary/entry/joule |date=2012-06-18 }}, Online Edition (2009).
