I'm not sure what one has to do with the other.
Well, it's got gravity already, that's why it's falling. It's just that nothing is pushing back on it, so it doesn't feel the gravity's effects on
it's mass (weight). It's why you feel gravity - because the Earth is pushing back on you, preventing you from falling (1 G).
As soon as it starts hitting resistance, it will decelerate and experience G forces (from the air pushing back on it), slowing it down. It's the
change in speed that work outside of gravities effects which create these artificial G forces.
So if you were sky diving, and you reach terminal velocity (max speed), even though you are in "free fall", you technically are experiencing just a
tiny amount of G forces, not 0 G, not 1 G, but something between, like 0.05 G. Close enough to feel "weightless" though.
