We have linear & angular velocities related by:(adsbygoogle = window.adsbygoogle || []).push({});

v=r.omega.

&

a=r.alpha

On my text book it's said" Above two equations show that on a rotating body,points that're at different distances from the axis do not have the same speed or acceleration,but all points on a rigid body rotating about a fixed axis do have same angular displcement,angular speed & angular acceleration at any instant".Plz. explain this statement.Thanks.
