Force vector

A force is always directed in one direction. Two arrows on a line of a force vector are wrong. In the case of the surface tension causes each particle a force to the particle itself. -- Con-struct (talk) 11:55, 18 May 2012 (UTC)

please keep as original version

@Roger Burger: @Con-struct: You guys have modified this from the 2008 version of User:Chris-martin, which was equivalent to the original png:

Please note this kind of changing of the meaning of a commons file is frowned on unless there is an obvious error. See: Commons:Overwriting existing files.

(The changing to single-ended arrows from the original double-ended arrows (and, changing their direction) is a change in the meaning, and not necessarily helpful. As suggested by this article, this exact kind of figure might only serve to create confusion. See also the review of the enwiki article which references the figure. The double-arrow version of this diagram at least does allow to think of the arrows as interactions that get cut by the surface, whereas single-ended arrows oblige us to think of them as forces, which seems to be a deprecated way of discussing the topic. However that's besides the main point, which is that you shouldn't overwrite files like this.)

Anyway, for the record the original is now more faithfully represented here: File:WassermoleküleInTröpfchen-2.svg .

Nanite, the original image contain an obvious mistake. Forces on a body or on a particle act only in one direction. That's an vector. Two arrow lines are wrong. --Con-struct (留言) 19:36, 19 July 2020 (UTC)
