In uniform circular motion, what are the ?average? velocity and ?average acceleration for one revolution? Explain.

Solution 10DQ Since velocity and acceleration are vector quantities the rotation of these vectors is 360 degrees in one complete revolution and the average is zero. Because it changes direction as it goes around the circumference of the circle . (After 1 revolution,as the final and initial position is same in case of circular motion. Hence total net displacement will be zero resulting in zero average velocity and acceleration.)
