Who can answer this technical conundrum and apparent paradox re ft/lb energy?

[Turnup]

For an airgun forum this thread is getting very esoteric, but interesting nevertheless.


Yes, the energy unit kWh, i.e (power X time), does of course have the correct dimensionality for energy when you work it out.

But this is simply an assertion on your part (which I am not necessarily disputing).


When I think about electrical energy, I can't see where mass and velocity squared comes into it. Sure I can see that we can express energy in a variety of units by a conversion constant which has no dimension and I can intellectually accept these as equivalents but this does not mean that they are the same thing. If electrical energy is mass times velocity squared, the mass and velocity of what?

Show the proof starting from W-h = voltage * current * time
