(as adjective) relating to, producing, or designed for a condition of zero gravity; (as noun) zero gravity: the state or condition in which there is no apparent force of gravity acting on a body, either because the force is locally weak, or because both the body and its surroundings are freely and equally accelerating under gravity; (also) a device or system that negates the force of gravity; cf. slightly earlier null-grav n.
You're about my age—you must remember when they shot the parts of the first moon rocket up to the Space Station. Alphonse Craig was putting them together.

Leo released his seat restraints, and stretched and relaxed in the pleasurable familiarity of weightlessness. Not for him the unfortunate nauseas of null-g that sapped the efficiency of so many employees.
