Question

If the speed of a moving object A is $am{s}^{-1}$ and its velocity is $bm{s}^{-1}$,what is the similarity you observe?

Answer 1

Step 1: Given data and to find

A body has $speed=am{s}^{-1}$and $velocity=bm{s}^{-1}$. We need to find the similarity between them.

Step 2: Definition

1. Speed is defined as the distance travelled by the body at a particular time interval. Its SI unit is $m{s}^{-1}$.
2. Velocity is defined as the displacement of the body at a particular time. Its SI unit is $m{s}^{-1}$.

From the above 2 definitions, it is clear that even though speed and velocity are two different quantities, It's SI unit is same i.e. $m{s}^{-1}$.

Thus, the similarity we observe is both have the same SI unit of $m{s}^{-1}$.
