# 601 Angular Velocity

How do the linear velocity v and angular velocity ω of these two circular motions compare?

$v=r\omega$

These two circular motions have the same ω. The blue one has twice the radius, so its v is double that of the red one.

$\omega =\frac{v}{r}$

These two circular motions have the same v. The blue one has twice the radius, so its ω is half that of the red one.
