Gravity and Motion
... Given two masses anywhere in the Universe, these two masses have an interaction that diminishes with distance. In fact it diminishes with the square of the distance that seperates them. This interaction is the Gravitational Force. Let’s look at the equation for this interaction more closely... F = ( ...
