This article aims at clearing the usual misconceptions about weightlessness and strengthening the foundations of the concept of gravity in a layman’s language. This project is for readers who don’t even have a background of high level physics. Not all of us are well versed with the language of mathematics and hence is sparingly used in this paper In the concept of weight and weightlessness are poorly misconceptions. It is seen that notion of weightlessness would mainly spacecraft free falling or elevator in the mind. But the issue is that is the object in this case really weightless? in this paper there is an attempt to survey and analyze the concept of weightlessness Especially in the Spacecraft. In this work the first is review preliminary concepts of motion, acceleration, mass, weight, inertial frameworks and non-inertial frameworks in connection with this issue and final using these concepts and the scientific method the weightlessness dynamics has been investigated.
