WebConsider a satellite of mass m in a circular orbit about Earth at distance r from the center of Earth (Figure 13.12). It has centripetal acceleration directed toward the center of Earth. Earth’s gravity is the only force acting, so Newton’s second law gives WebThe acceleration an object feels from gravity is just MG/ (r 2 ). If we plug in values for Earth's mass and the Moons mass and look at a couple of different orbital locations we can get a feel for the relative pull between the earth and the moon. For a satellite on the outer edge of Low Earth Orbit (LEO), the orbital distances is about 2000km ...
