Vedclass · Answer

(D) Average speed is defined as the total distance traveled divided by the total time taken,while average velocity is defined as the total displacement divided by the total time taken.For the magnitude of average speed and average velocity to be equal,the total distance traveled must be equal to the magnitude of the total displacement.This condition is satisfied if and only if the particle moves in a straight line without changing its direction of motion.If the particle turns back,the distance traveled will be greater than the magnitude of the displacement,making the average speed greater than the magnitude of the average velocity.

If the magnitude of average speed and average velocity over an interval of time are the same,then:
