Question

Give the SI unit of acceleration.

Answer 1

Step 1: Finding the SI unit of acceleration

1. We know that a change in velocity with respect to time gives acceleration.
2. we know that acceleration $\left(a\right)=\frac{v-u}{t}$ ……(I)
3. Here v is final velocity and u is initial velocity and t is time.
4. We know that change in velocity unit is $\frac{m}{s}$ and time unit is $s$.
5. Putting the above unit in the (I) equation we get $\left(a\right)=\frac{{\displaystyle \frac{m}{s}}}{s}=\frac{m}{s^2}=m{s}^{-2}$

Hence the SI unit of acceleration is $m{s}^{-2}$.
