artificial gravity

Spin-induced downward pull

Artificial gravity is simulated gravitational force produced by mechanical means, especially rotation.

In science fiction, spacecraft spin to create centrifugal force that pushes occupants toward the outer hull, mimicking gravity.

The concept addresses the health problems of prolonged weightlessness: The station's rotating ring provides artificial gravity for the crew.
