Scientists at NASA and Indian Space Research Organisation are designing a rotating space station ring to simulate Earth-like gravity for astronauts.
Astronauts stand on the inner surface of a rotating circular ring. The rotation creates centripetal acceleration, which feels like gravity.
Engineers must calculate the angular velocity required so astronauts experience acceleration equal to Earth's gravity.
A circular space station ring has radius r.
To simulate gravity g, centripetal acceleration must equal g.
Find required angular velocity ω.
