Sorry Larry but you are not correct.  Work over a given amount of time, equates to power.  Work/Time = Power

So you can evaluate the total work that you put into the system over a certain period of time and get an average input power value.

You can also evaluate the total work that you put into the system over a certain period of time and get the total input work.

Likewise, you can evaluate the total work that you get out of the system over a certain period of time and get an average output power value.

You can also evaluate the total work that you get out of the system over a certain period of time and get the total output work.

Average input power vs. average output power or total input work vs. total output work are virtually the same thing. 

One factors in a time period to create an average power level and they other simply factors that same time period but only counts the total work.

So it's a phony issue and there is nothing to discuss.   Which brings us back to the beginning:  What are the input vs. output measurements or calculations done in your spreadsheets?   You can use work or average power, it doesn't matter, the same relevant data is conveyed in either measurement method.

I had just deleted my post, because I didn't like parts of it, when I seen yours.

'Sorry Larry but you are not correct.  Work over a given amount of time, equates to power.  Work/Time = Power'. What a liar, I had just stated that Work without Time was useless as Power is equal to Work/Time.


First you stated ' it's work: force x displacement' in reply 1206, and fletcher stated ' Work [f x d]' in reply 1207. Now you are claiming new definitions that you did not state. All of your new definitions contained 'certain period of time'.  I did not know, but you are obviously a deceiver and this will be my last response to you.

LarryC:

I won't argue this with you.  I suggest that you go to an educational web page and read up on energy and work and power and all that stuff.

One of the best sites is the hyperphysics web site - it is down for me at the moment.

Search on google .... Hyperphysics Work Energy Power

So don't tell people to keep their comments Wayne.
Bye Bye

can you apply this to your own comments ?
