Re: [Phys-l] "Flow"



"Would you consider not using the term "transferred" as well? If it is a property of a system, its magnitude can be changed, but not moved independently."


Well, since it's not the same energy * I suppose transferred isn't a good idea either.

* Ha! is it? can we label different energies to keep track of them?

bc, would apply to green paint, if scrapped off and then pasted on the next object.

reminds me of nuclear (particle) reactions. Say a collision in which the "bullet" appears after the collision. I don't think the researchers think it's the same one.

I answered the question for myself by using google (etymonline.com).
From the similarity in the roots and the words themselves, I think the
idea of flow should be eschewed by instructors of beginners, except for
(with) real (as opposed to imaginary) fluids, e.g. water, gasses, ions,
etc.


You seem to agree with Larry here, but I wonder if it should not be eschewed by "instructors" everywhere. Medical language seems to be very precise perhaps for a reason. Here on this list our discussions sometimes seem to get bollixed up because the language looses precision.



p.s. momentum is transferred from one object to another by work (+ & -)
during a collision?


Or as a result of any kind of interaction? As in the Joule case?

Would you consider not using the term "transferred" as well? If it is a property of a system, its magnitude can be changed, but not moved independently.

Thank you for your helpful reply.
