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. WebThe potential at the center of the Earth is the integral of the gravitational acceleration [math]g (r) [/math] from the reference point (say sea level) to the center. That depends on the density of materials too deeply buried to measure directly, though we have Continue Reading Jonathan Adams
