Hello, I'm DVdm. An edit that you recently made to Newton's law of universal gravitation seemed to be a test and has been reverted. If you want to practice editing, please use your 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) 12:56, 22 March 2021 (UTC)
