6.1 Angle of Rotation and Angular Velocity

The equation v = r ω v = r ω says that the tangential speed v is proportional to the distance r from the center of rotation. Consequently, tangential speed is greater for a point on the outer edge of the CD (with larger r) than for a point closer to the center of the CD (with smaller r).This makes sense because a point farther out from the center has to cover a longer arc length in the same
