What is Weightlessness?
Answer / gaurav saxena
Weightlessness:-When a body or a spacecraft is moving in an orbit around the earth, the centrifugal force on it acts in the direction opposite to that of its weight with, which it attracted towards the earth. For a particular orbital speed (at a given height) the weight of the body is neutralized by the centrifugal force acting on it and the body becomes weightless. The absence of any apparent gravitational pull on an object is weightlessness. Absolute weightlessness is obtained, only by an object falling freely in Vacuum, an orbiting satellite is a special case of tree fall. The state of weightlessness is also induced when a body moves at a speed sufficient to counteract gravitational pull of any other object upon it
