Question

derivatation of 1st equation of motion
v=u+at​

Answer 1

Answer:

To derive v =u+at

Explanation:

OC=AD=Time(t)

OE=CB=Velocity(v)

OA=Initial velocity (u)

OE=OA+BD

v=u+BD ------(1)

Now we have to find the value of BD:

Slope =BD/AD

a=BD/t

BD=at. --------(2)

Putting (2)in (1)

v=u+BD

Therefore, v=u +at

We use velocity time graph to derive equation
