Maybe, and then again, maybe not. Let's look at a couple animations. First, here's an animation of the effects of gravity on a person riding in a very untrustworthy elevator. Next, look at an animation on free fall using a ball , courtesy of the Mission Operations Lab at Marshall. Then come back to this page for more detailed explanation.
Gravity is a result of a basic property of all objects in the universe.
The more massive the object, the greater its gravity. An object's gravitational field attracts another object with a force that is related to the distance between the centers of the two objects and their masses. F is the gravitational force between the two objects, m 1 and m 2 are the masses of the two objects, and r 2 is the square of the distance between the centers of the two objects. As two objects get further apart, their mutual attraction decreases pretty fast. You can see that, mathematically, the gravitational force between two objects can get very small, but it can never be quite zero.
