Question

17. What is the numerical ratio of average velocity to average speed of an object moving along a straight line path? A. 2:1 B. 1:2 C. 1:1 D. 1:4

Answer 1

Answer:

The body is moving along a straight line path. (Assumption: Displacement is always increasing)

This means that its distance and displacement are going to be the same.

As a result, speed and velocity are also the same.

So, required ratio is 1:1

(There is one thing to be considered.

If body, while moving on its path, stops and moves in backward direction, then displacement will be less than distance travelled. In this case, ratio will be less than 1)
