gravity is what we call the force exerted by one atom on all other atoms. in theory, the atoms of your body are pulling on the atoms of the farthest galaxy. with the understand of the principle of a force being exerted is the square root of the distance, we can of course see that your not having much affect. the effect is acculative. meaning that when all the atoms of the earth exert the force on the ball, the ball is pulled towards the earth and the earth is pulled towards the ball by 32 feet per second. due to its considerable more mass the earths enertia does not allow it to move much, but the ball moves easily.
this force is applied constantly, meaning that its not actually happening in seconds and foot, but in millseconds and micro inches and smaller. in each of those measurement, the enertia of the object has been affected, so in the next measure, the object is already affected, and is affected anew.
