Is the Relation v=rw Valid for Non Uniform Circular Motion?

[torquemaster]

1. we can derive that v=r$$\omega$$ for uniform circular motion as v=2$$\pi$$r/T and $$\omega$$=2$$\pi$$/T but does the relation v=r$$\omega$$ also hold for non uniform circular motion where $$\omega$$ is a variable quantity

Sure, v =wr is the conversion from angular speed to tangential speed . v will also be variable if w is variable (accelerated motion).
