<span>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. </span>
As you throw the ball up into the air, its direction is up, but the speed decreases due to the pull of gravity. The ball slows down, and at the very top of its flight, its velocity at that instant is zero.
