WEIGHTLESSNESS Meaning and
Definition
-
Weightlessness is a physical condition experienced by an object or person when they are not subjected to the force of gravity or when the force of gravity is negated. It is a state in which an individual or an object lacks weight and experiences a sensation of floating or free-falling. In this condition, the effects of gravity on the body or object are greatly reduced or eliminated, resulting in a feeling of weightlessnes.
Weightlessness is often encountered in situations where individuals or objects are in freefall or orbiting around a celestial body. Examples include astronauts in space, parabolic flights, or extreme sports involving freefalling. In such situations, the gravitational force acting on the object is balanced or neutralized by the centripetal force or acceleration due to the motion.
The sensation of weightlessness occurs because the object or person is no longer pulled downwards towards the earth's center of mass. As a result, gravitational forces that would normally cause objects to fall or individuals to experience weight are absent, leading to a perception of being weightless.
Furthermore, weightlessness affects various aspects of an object or person's behavior. For example, objects or individuals in a state of weightlessness will not rest on a surface but instead float freely. Additionally, the behaviors of fluids, gases, and other materials may also change in a weightless environment.
Overall, weightlessness is a state of being where the sensation of gravity is eliminated or significantly reduced, resulting in a feeling of floating or free-falling and altered physical behaviors.

Etymology of WEIGHTLESSNESS
The word "weightlessness" is derived from the combination of the noun "weight" and the suffix "-less".
The noun "weight" originated from the Old English word "wiht", meaning a thing or an entity. It later evolved to "weight", referring to the measure of the force exerted on a body due to gravity. The Old English word can be traced back to the Proto-Germanic word "wihtiz", which also meant a creature or thing.
The suffix "-less" is used to form adjectives indicating the absence or lack of the characteristic described by the root word. In this case, "weightless" describes the state of lacking weight or experiencing a sensation without gravitational force.
