Derive the equation V = u + at

$\huge\fcolorbox{red}{yell}{Proof}</p><p>$

By defining acceleration is the rate of change of Velocity. So we write

$\boxed{ \frac{Acceleration \: = \: Change \: in \: velocity}{time} }$

Now, Change in Velocity

= Final velocity (v) - initial velocity (u)

If t is the time taken to change the velocity from u to v then Equation (1) can be written as

$a \: = \frac{v \: - \: u}{t}$

Now we have to cross multiply.

at = v - u

v = u + at

✐ Hence Proved
