# Angular Velocity Review

A Ferris wheel has a radius of 8 meters and rotates once every 15 seconds.

A 10:1 scale model of the Ferris wheel also rotates once every 15 seconds.

Which has the higher Angular Velocity?

Solution: angular velocity = Change in rotation/change in time

Do I use the formula v = rw
I don’t understand where to start this problem.

Make a drawing of the big ferris wheel and on the same paper draw the smaller one. Make one rotation of the paper in 15 seconds. The big ferris wheel rotated through 360 degrees. What about the smaller one?
Do their angular velocities differ?

They are the same.
