What is the angular speed limit, like linear speed limit is c?

    what is the angular speed limit, like linear speed limit is c??

    does there exist an angular speed limit, just like we have 'c' in relativistic mechanics?
    If Yes, How?
    If No, Why?

    At the simplest level, it depends on radius. Radius * angular speed < c is required. I doubt there is any other fundamental (rather than practical) limit.

    Well, obviously no tangential velocity can exceed that of light. The maximum angular velocity would therefore depend on the radius of rotation. So, to answer your question, yes and no; there exists a maximum angular velocity which is determined by radius of rotation, but it is not fundamental the way c is.

    so should it be c/R?? (as I was expecting!)
