Keep in mind this relationship
1. Relationship between Speed, Distance and time
→Distance = Speed × Time
2. Relationship between Displacement, Velocity and time
→Displacement = Velocity × Time
So, velocity is zero only when
Displacement= 0,so when motion is circular motion,
Total Displacement =0 because initial and final position are same.
But , Speed is not zero, because
Total Distance Traveled = 2 π × (Radius of circle).
So, Option (A)The Starting and end point are same .. . . . in which the velocity is zero but the speed is a nonzero quantity.
