How does centripetal force produce artificial gravity

I think I lack a fundamental knowledge of physics to answer this myself. In many sci-fi stories, there is a rotating spaceship that gives the feeling of being pulled "downwards" against the sides of a ...

Could the ISS be spun to simulate Phobos' gravity?

Before a human crew goes to Mars' moon Phobos or to even lower mass asteroids, could a long stay at such an object be simulated gravitationally in the space station? I've heard that the ISS people don'...

Why is artificial gravity not included on space stations? [duplicate]

I'm wondering why artificial gravity is not included on the ISS, or on the currently planned OPSEK. There are long-term health effects of weightlessness, which would be avoided, using artificial ...

What would a physically correct term be for “artificial gravity by rotation”?

Microgravity causes some health concerns in the long run, so it has been proposed that one could create what is often called "artificial gravity" by rotating the space station. This is not strictly ...

How could a spacecraft be continuously propelled if it rotates to simulate gravity (by tether)?

For long term crewed space travel, gravity might be simulated by rotating a habitat in a long tether to a counter weight. Conventional chemical rocket engines give a spacecraft a brief initial impulse....
