These equations describe relation between initial velocity (u), final velocity (v), displacement(s), time (t) and acceleration (a), for uniformly accelerated motion.                        


First equation

 v = u+at

Second equation

s= ut+ at2

Third equation

 v 2- u=2as


Distance traveled in nth second (Sn) is the distance traveled in one second between t = n and t = n-1 seconds

Sn=u +  (2n-1)
