Can gravity exist without rotation?

No, the Earth has gravity just because it has mass. It would have almost exactly the same gravity even if it wasn’t spinning at all. The gravitational effects of its spin are extremely subtle, and have not yet been reliably measured.

How do you make artificial gravity?

Artificial gravity can be created using a centripetal force. A centripetal force directed towards the center of the turn is required for any object to move in a circular path. In the context of a rotating space station it is the normal force provided by the spacecraft’s hull that acts as centripetal force.

How can you create artificial gravity in space?

How do I create artificial gravity in space?

Dave: In space, it is possible to create “artificial gravity” by spinning your spacecraft or space station. When the station spins, centrifugal force acts to pull the inhabitants to the outside.

Can you create gravity by rotating a city in space?

By rotating a city in space you would not create gravity, you would simulate it. Assuming your city was ring-shaped, and spinning fast enough, everything in it would feel a force pulling them outward, but it would be the centrifugal force, not gravity. For most purposes, it would act in a similar way, but it would not be identical.

Is there a way to create gravity without mass?

Ryan: As far as anyone knows, there is no way to produce gravity other than with mass. Things that have mass have a certain amount of gravity and will interact with other things that have mass. By rotating a city in space you would not create gravity, you would simulate it.

Could a rotating room give astronauts artificial gravity in space?

On the International Space Station, astronauts have to do everything while floating free. A rotating room might give them artificial gravity — if they can take the spin. NASA Smaller rotating objects can provide the same effect as O’Neill cylinders.
