Talk:Point mass

From the article:

When none of the object's circumferences from the center of mass overlap, it becomes possible to think of the center of mass containing all of the mass of the object.

What does this mean? What's a "circumference from the center of mass"? How can an object have more than one? In what ways can they overlap? 70.52.180.58 (talk) 17:34, 6 July 2008 (UTC)[reply]

I updated that sentence- thanks for pointing it out.

The circumference from the center of mass of a round object is defined as all of the points in a sphere (where the center is the center of mass) that are the same distance from the center as the mass in the object farthest from the center. Hope this is helpful. Beast of traal T C _ 01:33, 10 July 2008 (UTC)Beast of traal[reply]

Merge proposal

I propose to merge this article in point particle and to trasform this page in redirect to that article. This will be better for both articles (and it follows the principle general contains particular, which is good). --CristianCantoro (talk) 10:53, 22 May 2009 (UTC)[reply]

I agree. --Vanuan (talk) 16:45, 17 June 2009 (UTC)[reply]

I agree. This will expand the content in the Point particle article, and allow people to get a sense of Point particles and their properties. This would be a useful reference to other articles that discuss point charge, point mass, and point particle. Ti-30X (talk) 19:46, 29 June 2009 (UTC)[reply]
