Zero Gravity

Definition

The condition of apparent weightlessness experienced by objects or people in free fall or orbiting in space, where gravitational forces are balanced or absent, resulting in the sensation of floating.

Example Usage

Astronauts conduct experiments in zero gravity aboard the International Space Station to study how materials behave without weight.

Origin

English compound term combining 'zero' (from Arabic 'sifr' via Italian) and 'gravity' (from Latin 'gravitas' meaning weight or heaviness).

Fun Fact

Zero gravity isn't the absence of gravity but rather constant free fall; astronauts and the spacecraft are all falling together around Earth at the same rate.
