potential For a conservative force F, a scalar field ϕ such that F = ∇ϕ. If the domain of F is path-connected, then ϕ is unique up to a constant. If, as is conventional, gravitational potential ϕ is defined as gravitational potential energy per unit mass, then F = −∇ϕ, where F is the gravitational field.
