How does free falling in a plane simulation weightlessness in space?

Answer 1

Because weightlessness is literally free-falling in space, so a free-falling plane would go fast enough to simulate the 'weightlessness' feeling.

Answer 3

Imagine yourself flying in a plane. You still feel Earth's gravity holding you in the seat, or holding your feet against the floor of the cabin. But you don't feel the speed of the plane pulling you against the back wall, because you and the plane are going at the same speed. Now what if the floor was dropping away from you at the same rate you were being pulled towards it by gravity? Just as the forward motion of the plane doesn't throw you to the back of it, you would no longer feel your weight on your feet. Now suppose you jump a few inches. You'll never come back to the floor because the floor is falling away from you at the same rate you are falling towards it. You are, effectively, weightless within the plane.

That's how it works. And it's the same reason people are weightless in space. You and the plane are all moving at the same rate in the same direction.

Answer 4

U fall at the acceleration of gravity and so every things appears without gravity.
