Definition: scalar quantity equal to the scalar line integral of a force F acting on a particle along a given path C, thus W = ∫C F ⋅ dr, where dr is vector line element

NOTE 1 Work is energy transferred in a special manner and thus is a process quantity (113-04-10). Work W changes the internal energy E (113-04-20) of a body for ΔE = W, where E is a state quantity (113-04-09).

NOTE 2 In applications, work is often calculated as the time integral of power P: W= t 1 t 2 Pdt MathType@MTEF@5@5@+= feaagKart1ev2aqatCvAUfeBSjuyZL2yd9gzLbvyNv2CaerbbjxAHX garuavP1wzZbItLDhis9wBH5garmWu51MyVXgarqqtubsr4rNCHbGe aGqk0di9Wr=fpeei0di9v8qiW7rqqrVepeea0xe9LqFf0xc9q8qqaq Fn0lXdHiVcFbIOFHK8Feea0dXdar=Jb9hs0dXdHuk9fr=xfr=xfrpe WZqaaeaaciWacmGadaGadeaabaGaaqaaaOqaaiaadEfacqGH9aqpda WdXaqaaiaadcfajugabiaacsgakiaadshaaSqaaiaadshadaWgaaad baGaaGymaaqabaaaleaacaWG0bWaaSbaaWqaaiaaikdaaeqaaaqdcq GHRiI8aaaa@43D5@ .
