For the rotational motion, on my book, it says "Since w (angular velocity) is the same for all points of a rotating object, a (alpha) also will be the same for all points.w and a are properties of the rotating object as a whole." The thing that I don't get is that why velocity is the same at all points no matter if there is an acceleration? Its speed is supposed to increase at each point? Hope you can explain, thank you.
