This is an approximation, and what I want to do in this video is figure out if this is the value we get when we actually use **Newton's Law of Universal Gravitation** and that tells us that the force of gravity between two objects, (and let's just talk about the magnitude of the force of gravity between two objects) is equal to the universal gravitational constant times the mass of one of the bodies, m1, times the mass of the second body, divided by the distance between the center of masses of bodies square.
