Someone has replaced the redirect with a poorly-written essay, possibly copied from some foreign text book. Should we restore the redirect to Centre of mass? Dbfirs 20:59, 18 March 2016 (UTC)[reply]
Yes, I'm in favor of a redirect! Despite the title, the content of the present article is really about the center of mass, and in fact the lead paragraph admits "It is also known as the 'Center Of Mass'". That's a clear case where a redirect is appropriate. Melchoir (talk) 22:57, 18 March 2016 (UTC)[reply]
The article has been cleaned up a bit, and edits have been made in good faith, so I'll not revert without an overwhelming consensus. Dbfirs 09:12, 20 March 2016 (UTC)[reply]
Is this article just going to be a simplified version of our article at centroid? Dbfirs 19:52, 21 March 2016 (UTC)[reply]

I agree that this article was written in good faith, but I still think it should be deleted and replaced with a redirect to Center of mass#Center_of_gravity. Reasons:

  • The definition given in this article is unclear (what does it mean for a resultant force to "pass through a point"?) and is incorrect in case of non-uniform fields.
  • All formulas given in this article are either centroid or center of mass calculations; no separate article is needed for these.
  • The subtleties of the notion of center of gravity in non-uniform fields are properly explained in Centers of gravity in non-uniform fields.

I agree, and have now implemented that redirect. The article was really mostly wrong, in that it gave information about centroids and centers of mass, but claimed that it was information about centers of gravity. (Of course, they're often the same, but that doesn't mean that formulae for one can be passed off, with no caveats, as formulae for the other.) The now-redirected-to section ironically gives much more information about centers of gravity. —RuakhTALK 21:14, 14 October 2016 (UTC)[reply]
I've no objection to restoring the redirect, but we have now lost some useful content. Where should it be copied to? (Or is it already somewhere else and I've missed seeing it?) Dbfirs 08:48, 16 October 2016 (UTC)[reply]
I think that the article's useful information was all already in Center of mass or Centroid, albeit not in the same form. —RuakhTALK 20:32, 18 October 2016 (UTC)[reply]
