# PHYSICS

All of us are familiar with the formula Power= Work/Time

We have derived a new formula for Power.....


Power = mav where m = mass a = acceleration v = velocity PROOF :- P = W/t

                     P= Fs/t    where       F = force and s = diplacement .


Therefore,

                     P = ma x s/t ,

P = mav      coz      displacement/time gives u the velocity &
"The speed need not be constant"


HENCE THE FORMULA IS Power = mav

Work is not equal to power/time. But work is equal to Power*time!!!

thanks for correcting my post. it would have misleaded the people following me. I accidently put W in place of P and vice-versa.

No probs...:):)

Be specific ! It is not valid always ... Actually It is Instantenous Power at time t=t , but for any time interval it is changes , and we have to find it's average value .!

So It is request to you please Re- Edit this note , so that It doesn't misguide other's Thanks !
