- i am not sure but i thought the velocity of a revolving particle is zero because the displacement of such a particle is zero. but i am saying once again that i am not sure. i have read all these so many years ago. :(

- 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 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............
