Kinematics of Circular MotionKinematics of Circular Motion

The radian is a measure of an angle. It is defined as the angle subtended by a circular arc with a length equal to the radius of the circle. 2 radians is equal to 360°. The period of an object in circular motion is the time taken for one revolution, whereas the frequency is the number of revolutions per second.  , Angular velocity is the rate of change of angle. This yields:

w = 2Pi f

w= frac{2Pi }{T}
