Hello. For free fall to occur, does the rate at which you fall have to equal the gravitational field strength at that point above the surface? If I'm in an airplane and accelerate towards the ground at an acceleration of 9.8ms^-2 equal to that of the Earth's gravitional field, then I experience zero g and therefore, weightlessness. Is that right? Also, if this is correct, and hypothetically I travel towards a black hole whose gravitational field strength is infinite, how would this work? Help please!
