Hello, I'm DVdm. An edit that you recently made to Angular momentum seemed to be a test and has been removed. If you want to practice editing, please use the sandbox. If you think a mistake was made, or if you have any questions, you can leave me a message on my talk page. Thanks! - DVdm (talk) 16:13, 25 September 2019 (UTC)
