acceleration = a

initial velocity = u

final velocity = v

time = t


\sf t_1 = time \: of \: initial \: velocity \\ \sf t_2 = time \: of \: final \: velocity

As we know


\sf \red {a = (v - u)/(t_2 - t_1) }

so further


\sf a = (v - u)/(t) \\ \\ \sf at = v - u \\ \\ \sf v = u + at

If we will make a velocity-time graph we will observe a linear curve

as shown in attachment

By definition of acceleration, we know that

Acceleration, a = Change in velocity / Time Taken

= (Final velocity – Initial velocity) / Time

= v-u/t

  • at = v–u or v = u+at
