v=u+at
This equation is a relation between initial velocity (u), final velocity (v), acceleration (a) and time (t).
s=ut+1/2 at²
This equation is a relation between distance (s), initial velocity (u), acceleration (a) and time (t).
v²=u²+2as
This equation is a relation between initial velocity (u), final velocity (v), acceleration (a) and distance (s).
** The main difference with v²=u²+2as to the others are, it does not depend on time.

u is initial velocity
a is accelaration
s is distance travelled.
t is time
v = u + at is used to calculate velocity (using time)
v² = u² + 2as is used to calculate velocity(using distance travelled)
