It doesn't?  Power = Energy/Time.   Joules per second.  Ergs per eon.  Electron-volts per attosecond.

Actually, I'll make this easier for you.......

I can talk about an observation of power over a period of time.  I can carry on a conversation talking about that power and the effect it has on a system over a period of time.  I can talk about how that system can change, make logical deductions and express some qualitative descriptions of outcomes - all without using any other terms in my conversation.  There is nothing erroneous in doing so.  There is also validity in such a conversation even if an explicit reference to time is not included, especially if there is reference made to clearly time dependent characteristics - such as "braking" (change in velocity) - and that is consistent with the logic flow of the conversation.

Yes, the term "energy" has a place, but the conversation doesn't need to use it.

You are so hung up about that ... and you couldn't be more wrong.

Sure there isn't a mirror in your way?

But you can never admit to them when they go against your beliefs and your responses are the worst kind of ignorance.  You introduce contradictions and deny their existence.

Agreed.

Speaking an an electronics nerd who skipped Physics, I think of power in Watts.  Watts = Volts * Amps, and there is no time dimension unless you consider that Amps = Coloumbs per second.  But that is a rate, not a duration.  Even Watt-hours is rate, or a quantity, with no particular duration (unless specified).  I look forward to some clarification.

But honestly, trying to fine-tune and correct these equations is fairly pointless when they do not reflect the actual characteristics of these DDWFTTW vehicles.

Be even funnier if this could be a warp field solution.
