Work and Gravitational Potential Energy

... In most cases this will be used when the potential energy is known as a function of x and y, U(x, y) to find the force in the x or y directions by differentiating U(x, y). For example the gravitational potential, UG = mgy, so the gravitational force is Fy = ‐ dUG/dy = ‐mg. And for a spring, US ...
