Question

What is the numerical ratio of average velocity to average speed of an object when it is moving along a straight path??

Answer 1

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)

Answer 2

Concept:

The entire distance traveled by an object is divided by the time it took to cover that distance to determine its average speed. It's a scalar quantity, which means its magnitude is the sole thing that defines it.

The change in position or displacement divided by the time intervals in which the displacement occurs is described as average velocity. Depending on the sign of the displacement, the average velocity could be positive or negative.

Find:

The ratio of average velocity to average speed.

Solution:

The body is going in a straight line.

This implies that its distance and displacement will be equal.

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

As a result, the needed ratio is 1:1.
