Force is gradient of potential

WebAug 11, 2024 · The infinitesimal increment of potential energy is the dot product of the force and the infinitesimal displacement, dU = − →F ⋅ d→l = − Fldl. Here, we chose to represent the displacement in an arbitrary direction by d →l, so as not to be restricted to any particular coordinate direction. In physics, chemistry and biology, a potential gradient is the local rate of change of the potential with respect to displacement, i.e. spatial derivative, or gradient. This quantity frequently occurs in equations of physical processes because it leads to some form of flux.
