n.
The condition of apparent weightlessness occurring when the centrifugal force on a body exactly counterbalances the gravitational attraction on it.
zero gravity
Noun
the state of weightlessness
zero gravity
The condition of real or apparent weightlessness occurring when any gravitational forces acting on a body meet with no resistance so the body is allowed to accelerate freely. Bodies in free fall (including trajectories like orbits) experience zero gravity; bodies at rest on the Earth's surface do not, since they are subject to the counterforce of the surface supporting them.
