In free fall the weight of a body will be zero or not?
Freefall is defined as the vertical motion of an object or body from a certain height, only under the influence of the earth’s gravity. Such a body is also called a freely falling body.
It is a uniformly accelerated motion that moves only in the vertical axis ("y" axis), with the condition that the initial velocity will always have to be equals to 0 and the acceleration will be the value of the gravity in the place of the motion (9.8m/s).
For example- A stone dropped in an empty well, A ball is thrown in a projectile motion.
In a free fall, the weight of a body becomes effectively zero, means there is still "weight", but it is not felt. And, we know that weight is due to the gravitational pull of the earth, as when it changes weight also get changed, like on the moon.
If there is gravity, there is always weight by F = m•a (or gravitational g). Only when there is no gravity at all then an object is "weightless".
