First Equation of Motion

it is denoted by

v = u + at

Final Velocity = Initial Velocity + Acceleration *  Time Taken

where

v = Final Velocity

u = Initial Velocity

t = time taken

a = acceleration

How is this Equation Derived

We know that formula for acceleration is

a = (v - u)/t

at = v - u

at + u = v

v = u + at
