A point moves on a circle at constant speed. How to express its velocity it terms of time?

Period of motion T is a time necessary to complete a whole revolution (360o or 6.28 radians). When a period T is small, it is more convenient to describe a circular motion using a frequency. Frequency f is a number of whole revolutions n made by a rotating body in one second. Calculate frequency of the rotating point using the formula:                  f = n / t and the measured values of n and t.

Initial Values of Parameters Radius of circle (r) 1 m Angular velocity (w) 0.5 rad/sec
