State the SI unit of acceleration due to gravity.

Acceleration: In simple words, the change in the rate of velocity with respect to time is known as acceleration.

The formula of acceleration:

$a=\frac{v-v_{\circ }}{t}$

here, $a$= average velocity

$v$=final velocity

$v_{\circ }$=starting velocity

$t$=time consume

Acceleration due to gravity:

1. Whenever an object falls towards the earth, it gains an acceleration. It is represented using g.
2. This is called acceleration due to gravity. Its SI unit is similar to acceleration.
3. It is $m{s}^{-2}$.
