discovery did not rotate, it had an internal drum. the russian craft in 2010 did rotate. not sure centripedal force would work, especially if you toss something into the air.
“not sure centripedal force would work, especially if you toss something into the air.”
It works. But things fall differently. It’s called the Coriolis Effect.
Here is how objects move within a spinning frame:

For example, if you throw something to someone else, it will follow a straight line, but the line will appear to curve relative to the ones throwing and catching.
Yes, you could levitate by slowing your velocity in relation to the moving floor, but as long as your body is moving with it, you will experience something very similar to gravity beneath you.
