Yes, I can provide a citation for that fact (except the amount you miss by, which I'm not sure of, but I know it's substantial).  And yes, I will put it in the article, along with other examples (some of which, like modleing gases, are already on this talk page).  The fact that I have not done so yet is not a useful thing to point out, so please don't.    

 == Cleanup == 

 William has raised one very good point.  This article is poorly-written, and it may be confusing to people who don't know already what it's talking about.  I've worked on the intro, but that's it so far.  I'll do more, but hopefully I can get some help.     

 : Yes. The article is very poorly written. Why was why reverting to this version was a very bad idea.  . 

 : I agree. I think the examples should probably just be blanked and started over again.   

 :: The examples are valuable; they do make the concept easier to understand, even if they could be better.  If one could be cleaned up and made concise (preferably regarding centrifugal force, as that seems most obviously fictitious), and placed before the formulas begin, it would be very helpful to laypeople.
