Write the equation of velocity of an object falling freely from height $h$.

(N/A) For an object falling freely from a height $h$ under gravity,the initial velocity $u$ is $0 \ m/s$.
Using the third equation of motion: $v^2 - u^2 = 2as$.
Here,$v$ is the final velocity,$u = 0$,$a = g$ (acceleration due to gravity),and $s = h$ (displacement).
Substituting these values: $v^2 - 0^2 = 2gh$.
Therefore,the equation for velocity is $v = \sqrt{2gh}$.
