Question 34

A constant force F F\,F acts on a body, and the body moves with a constant speed v v\,v in the direction of the force. Which expression for the power P P\,P delivered by this force is correct?

A

P=FvP = FvP=Fv

B

P=FvP = \frac{F}{v}P=vF​

C

P=Fv2P = Fv^2P=Fv2

D

P=12Fv2P = \frac{1}{2}Fv^2P=21​Fv2
