Is power a quantity defined by:
[tex]\frac{dU}{dt}[/tex] and [tex]\frac{dW}{dt}[/tex]
Is it just defined to be it, or can it be derived in terms of the other (I mean, dU/dt in terms of dW/dt and vice versa)?
I now there's physical motivation to it, but sometimes I just can't help trying to ponder how these equations came about, because textbooks sometimes won't explain explicitly the context about how they are being used.
