1. V = u + a t

When we do not have to look at distance S, but find other quantities

2 V² = u² + 2 a S

When we do not want to look at time, but at other quantities

3 S = u t + 1/2 a t²

finding distance traveled by an object with initial velocity u, acceleration a

and in time t

4 S = V t - 1/2 a t²

finding when V is given and not u

5 d or Sn = u + a(2n - 1)2 OR Sn = u + (n - 1/2) a

This is the distance traveled in the nth second only. time duration is only 1

second.
