How will the equations of motion for an object moving with a uniform velocity change?

(N/A) When an object moves with a uniform velocity,the acceleration $(a)$ is $0$ and the final velocity $(v)$ is equal to the initial velocity $(u)$,i.e.,$v = u$.
$1$. The first equation of motion,$v = u + at$,becomes $v = u + (0)t$,which simplifies to $v = u$.
$2$. The second equation of motion,$s = ut + (1/2)at^2$,becomes $s = ut + (1/2)(0)t^2$,which simplifies to $s = ut$.
$3$. The third equation of motion,$v^2 - u^2 = 2as$,becomes $v^2 - u^2 = 2(0)s$,which simplifies to $v^2 - u^2 = 0$ or $v^2 = u^2$.
