every body has its own weight due to the gravitational force acting on the body when any body has got a force opposite and equal to the gravitational force then that body is said to be weightlessness

(of a body) having no actual weight; a state in which an object has no actual weight (because it is in space and unaffected by gravitational attraction) or no apparent weight (because the gravitational attraction equals the centripetal force and the object is in free fall).

Weightlessness is a condition in which the body experiences zero external mechanical force like in a free fall condition where the gravitational force is acting but no upward force but when we are on ground we also experience upward force of ground which we measure it as weight .

An object in a straight free fall, or in a more complex inertial trajectory of free fall (such as within a reduced gravity aircraft or inside a space station), all experience weightlessness, since they do not experience the mechanical forces that cause the sensation of weight.

*Absence of gravity is known as weightlessness. An object in weightlessness has no weight, but its mass remains constant: and if the force of gravity is zero, then the weight will be zero. That is why weighing scales are of no use to us in space. *In weightlessness you have the impression of floating like a roller coaster suddenly goes down while in fact you are falling; you think you are in a vacuum, but in fact you are breathing. *On Earth, we feel as though we are very agile and free to move as we wish. But all our movements are in fact dependent on gravity. However, the absence of weight does not make things any easier in space, as any astronaut performing the same tasks we are used to performing on Earth. read less

If objects are falling in zero gravity then it's called as weightlessness.
