The potential gradient.

The potential gradient at a point in a gravitational field is the change in gravitational potential per metre.For a change in distance of Δr the potential changes by an amount of ΔV. The potential gradient is therefore ΔV/Δr.Since ΔV is work done per unit mass i.e. ΔW /m then it follows that
