Question

if a force F is applied on a body and it moves with velocity v , the power will be :


Fv

F/v

Fv2

F/v2

Answer 1

Hi!!!!!

Power = Work/ Time.

Work = Force x displacement

So, now

Power = Force ×displacement / Time.

But ,

displacement / Time = velocity

According to the question, Force is F and V is velocity so,

Power = F x v

But power is a scalar quantity so, we have dot product for power so......

Power = Fv or F.v

Hope you get the answer..

Pleased to help you.
