The S.I. unit for the rate of change of velocity is ______.

Which is the correct option among the following?

The rate of change of velocity is called accelaration.

The formula for calculating acceleration is

 $a=\frac{change in velocity}{time}$

where the SI unit of velocity is m/s and the unit of time is s.

As a result, the S.I unit of acceleration is $m{s}^{-1}/s$ = $\frac{\mathrm{m}}{{\mathrm{s}}^2}$ .
