This category is within the scope of WikiProject Physics, a collaborative effort to improve the coverage of Physics on Wikipedia. If you would like to participate, please visit the project page, where you can join the discussion and see a list of open tasks.
I created this category because there are currently many articles and some subcategories under Category:Energy, and I'd like to follow the request on the top saying "Articles in this category should be moved to subcategories when appropriate." This is not to say that other articles under category:energy are not related to physics; I just wanted a category for the pure physics topics. I'm not feeling strongly about the name; I think when the category is filled, it will be obvious what I meant, and people can think of a better name. — Sebastian 01:36, 30 November 2008 (UTC)
