Rotational relatiom

    we have in rotational motion a=rω,where r and ω are the radius of rotation and angular velocity respectively.What is a (tangential acceleration or centripetal acceleration)

    Surely [itex]v=r\omega[/itex]?

    The tangential acceleration would be [itex]a=r\alpha[/itex] where [itex]\alpha=\frac{d\omega}{dt}[/itex].
