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 the force.
They are training in zero-gravity conditions.
Astronauts experience zero-gravity conditions in space, allowing for unique experiments.
Simulated zero-gravity environments aid researchers in studying the effects on the human body.
Achieving zero-gravity is crucial for certain scientific experiments and space exploration.
The concept of zero-gravity challenges traditional notions of spatial orientation.
