Question

the weight of a body is zero during free fall.why

Answer 1

Every body on this earth is attracted by the gravitational pull of the earth. A freely falling object has weight W=mg, where W-weight, m-mass of the object and g-acceleration produced due to the earth’s gravity. An object kept in a lift which falls freely, weighs zero on the weighing machine, but its actual weight is still mg. This happens because the normal reaction force exerted on the object in the lift is equal to zero, and normal force equals to mg, which in turn equals the weight of the object.

Answer 2

Answer:

The fortune of nature is so overwhelming !

This is all because of your own weight and the gravitational pull towards the earth surface.

whenever , anything fall , with start of zero acceleration , the weight of the body is balanced by the gravitational force that is :

W = weight of body = M*g

M = mass of the body

g = gravitational constant (roughly 9.8 $m/s^2)$

E.g. = if you leave a coin without any starting force from any height then the motion will be called as free fall.
