Question

Differentiate between average speed and
average velocity. What is the relation
between the ratio of these two and the ratio
of distance and displacement?​

Answer 1

Explanation:

average speed :-

1. average speed is a scaler quantity .
2. total distance taken /total time taken.

average velocity :-

1. average velocity is a vector quantity.
2. total displacement /total time taken.

Answer 2

$\large{\underline{\boxed{ Answer}}}$

Average speed :- It is defined as the ratio to the total distance covered by a body to the total time taken to complete the journey is called average speed.

Average velocity :- The average velocity is the ratio of the total displacement covered to the total time taken by the body is called average velocity.

The relation between average speed and average velocity is given by :-

$\boxed{\sf</strong><strong>\</strong><strong>r</strong><strong>e</strong><strong>d</strong><strong>{\frac{</strong><strong>A</strong><strong>v</strong><strong>}{</strong><strong>A</strong><strong>v</strong><strong>→}</strong><strong> </strong><strong>≥</strong><strong> </strong><strong>1</strong><strong>}}$

where Av→is average velocity and Av is average speed.

The relation between displacement and distance is given by :-

$\boxed{\sf{</strong><strong>\frac</strong><strong>\</strong><strong>r</strong><strong>e</strong><strong>d</strong><strong>{</strong><strong>S</strong><strong>}{</strong><strong>S</strong><strong>→</strong><strong>}</strong><strong> </strong><strong>≥</strong><strong> </strong><strong>1</strong><strong> </strong><strong> </strong><strong>}}$
