The Wigthness

Weightlessness The definition and use of Weightlessness is difficult. Weight means the strength exerted by gravity, burdenless means the absence of such forces and legerity officially means the condition of zero gravitational force. In popular use, however, slantlessness (often with quotation marks) has the meaning given in the preliminary paragraph. Astronauts and cosmonauts in the International Space Station be state to meet weightlessness, even though, at an altitude of a some blow km, their weight (the gravitational force acting on them) is exactly active 10% less than on earth. Their grasp has a large receptive quickening towards the earth and their weight is the centripetal force producing it. However, the space station has (almost) exactly the same(p) acceleration towards the earth. Consequently, in the frame of the space station, an unsupported someone appears to father no acceleration and so his relative motility in this frame is the same as that of a i ndividual without weight in a spacecraft that is not accelerating. If objects be removed from a star, planet, moon, or other such huge body, so that they experience very little gravitational interaction with them, they would speak to the condition of zero gravity.

If they are close to a massive object, but are unornamentedly accelerating towards the mass by gravitational acceleration only, they are in  throw in the towel fall and are weightless. Physically, they both follow Newtons first law of motion which describes one-dimensional motion. Such a situation, except for microgravity effects and the in hom ogeneousness of the gravitational field cann! ot be distinguished from weightlessness due to the absence of gravity from a body nearby. As an example, an travel rapidly free fall trajectory results in the weightlessness of objects in a falling elevator. The same type of accelerated free fall trajectory causes weightlessness of objects in orbit  intimately the Earth. Such objects are in free fall toward the Earth, as in the falling elevator, but they...If you want to get a full essay, order it on our website: OrderCustomPaper.com
