| 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: .
NOTE 3 The coherent SI unit of work is joule, J.
