WebApr 8, 2024 · GPE = mgh. Gravitational Potential Energy Formula. The equation for gravitational potential energy is: GPE = m⋅g⋅h [where, gravitational potential energy is measured in joules (J) m is the mass measured in kilograms (kg) h is the height measured in meters (m) gravitational field strength (g) measured in newtons per kilogram] WebWhat is interesting about gravitational potential energy is that the zero is chosen arbitrarily. In other words, we are free to choose any vertical level as the location where h = 0 h=0 h = 0 h, equals, 0.For simple mechanics problems, a convenient zero point would be at the floor of the laboratory or at the surface of a table.
