Historical Examples of zero gravity
At zero-gravity, where physical exertion is slight, men can get along on small quantities of food.
Space resorts established for tourists; new sports made possible by zero-gravity, invented and advertised.
- the state or condition of weightlessness
- 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.
