An object that is in free fall seems to be

An object that is in free fall seems to be weightless, even though the

usual force of gravity is acting on it.

If the falling object happens to be a person, then every part of him is

falling at the same rate, so none of his internal organs are pressing

against anything like they normally do, and he has no sensation of weight.

If a bathroom scale happens to be falling with him and he places it under

his feet, it won't read anything, since the scale and the person are both

falling at the same rate.
