| Dec 2, 2014 at 22:19 | comment | added | Hypnosifl | @Joshua Benabou - It may seem bizarre, but it can be explained in the station's rotating frame in terms of the Coriolis force (due to the ball's tangential velocity) being larger than the centrifugal force, and pointing towards the center, so in the rotating frame the Coriolis force provides a centripetal force which allows for a circular orbit. I added a couple paragraphs with the needed math to the end of my answer if you want to see how it works. | |

| Nov 27, 2014 at 2:18 | comment | added | math_lover | The ball would then travel in a circle, as if it is in orbit, as Hypnosifi, suggested. That is pretty bizarre. | |
| Nov 27, 2014 at 1:59 | comment | added | DJohnM | If the ball is placed away from the axis of the to-be-built station, the observed behaviour is even more bizarre... | |

| Nov 27, 2014 at 1:19 | comment | added | Physicist137 | Your "naive" conclusion is right! Ball travels at constant velocity with respect an inertial reference frame because there's no external force on it. | |
