Question

The feeling of weightlessness occurs because _____________________.

Answer 1

Answer:

The feeling of weight is one of compression.

Explanation:

All your body is being pulled down by gravity yet your feet ( if standing) or your back or something is holding you up.  

Your body is compressed by the PAIR of forces and it is that compression that you feel.  

So when you remove the supporting force then all the body is free to move together and there is no compression within you.  

Hence you perceive no weight.

Answer 2

Answer:

The feeling of weightlessness occurs because of the absence of a force of support on your body.

Explanation:

In the cases in which your body's experimenting "free fall", that is to say, when it's falling at the same acceleration than gravity, it means your body lacks support. On the other hand, the sensation of having weight is produced because you stand on the floor or float in water, perceiving its support.
