Question

Which equation of motion gives relation between velocity and time

Answer 1

This equation is the relation among initial vlocity (uu), final velocity (vv), acceleration (a) and time (t)

                                           v=u+at

Answer 2

first equation of motion 
v = u + at
----------------------------------
second equation of mothin
s = ut + 1/2 at²
------------------------------------------
these are the equation of motion gives the relation between velocity and time

v = final velocity
u = initial velocity
a=acceleration
s = distance 
t =time
