Which is greater
Angular Velocity =
Where, = Angle Traversed and = Time Taken
One complete Round corresponds to angle =
Now, hour clock takes 12 hours to complete one round.
So, angular velocity =
Earth takes 24 hours to completely revolve around its axis.
So, earth’s angular velocity =
Thus, the angular velocity of hour hand of a watch is greater than the angular velocity of earth about its axis.
