        the displacement of a revolving particle is not zero.............. if the radius of it's path is "r" and it transverses a angle "A"(which is the angular displacement) then it's linear displacement is "S = r * A" (the simple redian formula we all know)...

        however, displacement means the change of location of the CG . if the center of revolution is the CG then clearly, there is no displacement, hence zero

          however, 'displacement' means the 'change of location of the CG'.

          if the center of revolution is the CG then clearly, there is no displacement, hence zero velocity and acceleration :)

          but if the center of revolution is not the CG then the particle does have a 'speed' and a 'constantly direction changing' velocity and hence a constant acceleration.

          yes, you are right...... I was only considering a discreet body revolving about a discrete center......... as example, an electron around a proton............
