WebAs the potential gradient decreases, so does the gravitational field strength. KEY POINT - The relationship between gravitational field strength and potential gradient is: where ΔV is the change in potential over a small distance Δx. The concept of potential gradient is similar to that of the gradient of a hill or slope. Since the gravitational field has zero curl (equivalently, gravity is a conservative force) as mentioned above, it can be written as the gradient of a scalar potential, called the gravitational potential: In radially symmetric systems, the gravitational potential is a function of only one variable (namely, ), and Poisson's equation becomes (see Del in cylindrical and spherical coordinates):

WebThe gravitational potential gradient of a gravitational field is given by ΔV/Δr where ΔV is the change in gravitational potential between two points and Δr is the distance between those two points.
