WebOct 9, 2016 · A force field F = F ( r) is called a conservative force if it meets any of these three equivalent conditions: The force can be written as the negative gradient of a potential U = U ( r): (1) F = − ∇ U. Equivalently, condition (1) means that the one-form ϕ := F ⋅ d r is exact: ϕ = − d U, where the exterior derivative is d := d r ⋅ ∇.
