Please improve this image. It was written quickly by a student "best in class" (actually only). This is a v:Wikiversity project and students are encouraged to improve it. This method of introducing images was inspired when I noticed the dearth of good physics diagrams on Wikipedia. It occurred to me that it would be fun to encourage students to make and remake them. --Guy vandegrift (talk) 02:00, 21 January 2015 (UTC)[reply]
