Question

why the numerical ratio of average velocity to average speed of an object when it is moving along a straight path is 1. Explain

Open in App

Solution

Because in straight line path there is no change in the direction of the object so average velocity is equal to the average speed of the object.So ratio of average velocity to average speed of an object when it is moving along a straight path is 1.
