I did grit my teeth, however, at "...Very cool. I did grit my teeth, however, at "Because the Moon is smaller and less massive than Earth, the force of gravity at its surface is about one-sixth as strong." That is likely to leave the impression that the size and mass differences both contribute to making the moon's surface gravity weaker than Earth's. But the size difference works in the opposite direction: g = GM/r^2 after all.<br /><br />Yeah, I'm a physics pedant.Mark Jacksonhttps://www.blogger.com/profile/16294712435189215667noreply@blogger.comtag:blogger.com,1999:blog-1568334561722760329.post-60596982465914298642015-07-29T00:10:21.227-07:002015-07-29T00:10:21.227-07:00VERY INTERESTING AND USEFUL INFORMATIONVERY INTERESTING AND USEFUL INFORMATIONAnonymoushttps://www.blogger.com/profile/02906694732755017633noreply@blogger.com
