Question

What is the SI unit of acceleration?

Answer 1

The acceleration in terms of velocity and time is,

$\text{Acceleration}=\frac{Velocity}{time}$

The SI unit of velocity is ms^-1 and the time is s.

Thus, the unit of acceleration is,

$$\begin{gathered} \text{Acceleration=}\frac{{\text{ms}}^{-1}}{s} \\ {\text{=ms}}^{-2} \end{gathered}$$

Hence, the SI unit of acceleration is ms^-2.
