Motion in A Plane
Question
Wired Faculty App

Two particles A and B start from P and move along a circular path in anticlockwise and clockwise direction respectively. They complete one fourth of the journey in same time. Do they have same average velocities?

               

Answer

The particles undergo different displacement. So, the two particles do not have the same average velocity. 
Here, the magnitude of displacement, that is, the distance travelled by the two partcles is same. Therefore, they may have the same speed.
