Mechanical energy

This peer review discussion has been closed.
I've listed this article for peer review because I want to take it to GA but am stuck right now as to what I need to do further to bring it to that level. I would like suggestions for mostly new content - I do know that it needs a copy edit and I will contact the Guild of Copy Editors when I am sure that I have enough content. If there is something you want to edit, feel free - but please leave a message if you are doing any major changes.

The article is fairly short - I've made it much longer than it was before I started, but honestly, this subject is pretty straight forward. It will be something that high school students will be looking up pretty much so in that way it is an important article.

Thanks in advance for your interest, -- Regards Mottenen (talk) 19:38, 18 October 2011 (UTC)

Comments from RJH:

• The article needs to clarify that the kinetic energy is with respect to an observer's frame of reference.
• In the equation for U, I assume that F is meant to be a function of the vector x?
• The article makes no mention of rotational energy, which can also be considered a form of kinetic energy. Only the kinetic energy based on velocity is covered.
• It does not cover kinetic energy at relativistic velocities. The listed equation for K is only accurate for non-relativistic velocities.

Good luck with the article. Regards, RJH (talk) 19:29, 21 October 2011 (UTC)

Ruhrfisch comments: Thanks foryour work on this article. Here are some more suggestions for improvement.

• A model article is useful for ideas and examples to follow. There are quite a few FAs in Category:FA-Class physics articles and some may be useful models for this article
• Ideally there should be an image in the lead section
• Nothing should be only in the lead as it is a sumamry of the rest of the article. Saying that the energy unit is named for Joule seems to only be in the lead, though.
• I would look at some textbooks and popular science books and perhaps other encylcopedias and see what they say about mechanical energy as a way of making sure this is comprehensive.
• When an abbreviation or symbol is used, introduce it on the first use of the property. So U for potential energy should be defined in the first paragraph of the General section (where potenital energy is first mentioned) instead of the third paragraph (where it is defined now). If a symbol has not been defined
• Abbreviations in the pendulum diagram also need to be explained (in the caption). Could this be used as the lead image?
• Avoid bullet point lists where possible - can these just be converted to straight prose?
• Seems odd that this is not mentioned in {{Footer energy}}
• Article is pretty short so there is not much more to say
• Please make sure that the existing text includes no copyright violations, plagiarism, or close paraphrasing. For more information on this please see Wikipedia:Wikipedia_Signpost/2009-04-13/Dispatches. (This is a general warning given in all peer reviews, in view of previous problems that have risen over copyvios.)

Hope this helps. If my comments are useful, please consider peer reviewing an article, especially one at Wikipedia:Peer review/backlog (which is how I found this article). I do not watch peer reviews, so if you have questions or comments, please contact me on my talk page. Yours, Ruhrfisch _><>°^° 20:17, 6 November 2011 (UTC)
