Encyclopedia: Weightlessness
Weightlessness is the experience (by people and objects) during free-fall, of having no apparent weight. Although the term 'zero gravity' is often used as a synonym, weightlessness in orbit is not the result of gravity itself being eliminated or even reduced significantly (in fact, the acceleration due to gravity at an altitude of 100 km is only 3% less than at the earth's surface — a person at rest at that altitude would plummet to earth at a familiar rate). Weightlessness (roughly speaking) occurs when a body (e.g. a person) is: falling freely; in orbit; in outer space (far from a planet, star, or other massive body); in an airplane following a particular hyperbolic flight path (e.g. the "Vomit Comet"); or one of several other (even more unusual) frames of reference.
