In this question, I'm not talking about particle spin.
I guess, when an object rotates, its atoms also rotate. When an atom rotates, its particles must move in space.
I wonder that if the particles have a direction.
Can they rotate or do they just move position around the axis (middle) of a proton so we consider that the proton rotates?
Let's think about single particles like electron instead of composite particles like hadrons.
Can electrons rotate ?
Edit : I think this is a simple and good question but I couldn't get a sufficient answer yet .
