Calculating Artificial Gravity: v, r & g

Click For Summary
SUMMARY

A rotating spacecraft generates artificial gravity through centripetal force, calculated using the formula a = v²/r, where 'a' represents centripetal acceleration, 'v' is the tangential velocity, and 'r' is the radius of the rotation. The apparent value of gravitational acceleration (g) experienced by astronauts on the spacecraft is not zero, as they are not in a weightless environment, nor is it equal to 9.8 m/s², which is the gravitational acceleration on Earth. Instead, the value of g on the spacecraft depends solely on the specific parameters of its rotation.

A rotating spacecraft uses centripetal force to produce artificial gravity. If i know the radius of the space station and how fast it spins at, what is the apparent value of g on the surface of the station?

I know how to calculate the centripetal acceleration: a=v^2/r

But I was thinking could it be just 9.8? or is it zero, because in space everything is weightless.
 
Physics news on Phys.org
well they're asking about the apparent g value which means what the astronauts feel the gravity is on the station. You're right, you have to use a=v^2/r because rotation is what is providing the artificial gravity. It's not 0 because they are not in fact weightless and it's not 9.8 because they are not on the surface of the Earth.
 
thanks :)
