Hello, I'm Excirial. I wanted to let you know that I undid one of your recent contributions, such as the one you made with this edit to Kinetic energy, because it didn’t appear constructive to me. If you think I made a mistake, or if you have any questions, you can leave me a message on my talk page. Thanks, Excirial ( Contact me, Contribs ) 19:31, 18 April 2013 (UTC)
