Question:
How will the equations of motion for an object moving with a uniform velocity change?
Solution:
Equations of motion of a uniformly accelerated motion of an object are
1. $V=u+a t$,
2. $S=u t+1 / 2 a t^{2}$,
3. $v^{2}-u^{2}=2 a S$.
When object moves with a uniform velocity, its acceleration, $a=0$. Hence equations of motion become
1. $V=U$,
2. $S=u t$,
3. $v^{2}=u^{2}$.
