Talk:Body force

From Wikipedia, the free encyclopedia

I had always thought "body-force" was the ratio of force to mass, not volume i.e. for gravitational force it is "g" or "g cos(angle)" if there is an angle between the direction of flow and the direction the gravity force acts.

There are some major mistakes on this page, or lack of information maybe. I changed the equation F=rho*a to F=rho*velocity squared*area as is shown in the fluids books.

I came here looking for a better understanding of body forces for my fluids class and,... no dice. eximo (talk) 01:13, 7 February 2008 (UTC)

Erm, that makes no sense. I mean, look at the units, that's not even force per mass. There are differing definitions of body force, mind you, and I have indeed seen force per mass in one context; force per volume is more common, and I've seen it both in fluid and solid mechanics classes and books. I've clarified the article why force per volume is favorable.

What major mistakes? Adding v^2 is a major mistake, a force in general doesn't need to depend on acceleration. -Ben pcc (talk) 03:20, 26 May 2008 (UTC)
