Yes. Air circulation in a space colony is a topic that's ripe for more
research. It's complex and I don't think very well understood yet.

Hmm, no. Even in a vacuum, at the moment you lose contact with the
ground you will continue traveling in a straight line at your current
velocity. That straight line leads to... the ground (which is
constantly accelerating "up" from your frame of reference). You come
right back down. The net effect is very much like gravity, whether
you're in contact with anything or not.

In fact even if the colony itself isn't rotating, you can get the same
effect if you move fast enough around a circular track, as demonstrated
on Skylab years ago: https://www.youtube.com/watch?v=Oi2R24pFYjk

(Ignore the sad ignorance of the conspiracy nut who posted the video.)
