* The centrifugal force is needed to describe the same motion, using coordinates, velocities and accelerations of a rotating frame of reference."
"But would a rotating frame of reference actually have any sense of rotation?"As long as you have a universe with 'matter' in it I would expect you to feel a 'centrifugal force' though, if you're the one riding the carousel I mean. I think that's what ...sorry, you cannot view external links. To see them, please
REGISTER or LOGIN wondered about too?==Ah I think I see what you was thinking of. If we assume a universe with stars you will have a reference telling you that you spin, but if you don't? How will you ever define your 'motion' and the 'force'?
A man in a cylinder that is relatively small and/or rotating fast enough would easily be able to tell what his situation was.
You have to set your parameters before this gets interesting. For example, if you were in one of those carnival rides where you get into a cylinder and when it rotates everybody sticks to the walls, it it easy. The people across from you feel gravity in the opposite direction that you do.
Geezer, if someone is unable to figure out that they are in a rotating cylinder based on the fact that they are in a circular room and the down direction rotates as one goes around the room,
Geezer, you are going to have to help me with this one. In the light of the fact that this is a science site, please tell me what real world "force field" you would invoke in your example. I don't really see how one could reasonably interpret the situation as other than a rotating cylinder, unless we are in the Star Trek universe. Steve
Geezer, with your doughnut hole within a massive structure there wouldn't be the Coriolis effects I described.
Geezer, you are attaching a little too much importance to this.
