How to know if a force is body force or not?

  1. Jan 15, 2013 #1
    If, in a problem, I want to know if a given force is body force or not, what should I do? for example- a rod rotating about an axis, how will I know if the centripetal force is Body Force or not?
    (body forces are those forces which depend on volume)
