zero gravity
n
(Physics / General Physics) the state or condition 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.
