I really wish the video makers\/interviewer had drawn a better distinction between the granite globe and the earth.  The globe in the video was certainly not created spinning as it is, and we know there is friction, so asking why it&#8217;s spinning (or not stopping, at about the 1:00 mark) is really the wrong question if you are going to discount answers that say it&#8217;s because there&#8217;s a force (or torque) on it.  I&#8217;m not sure if I wouldn&#8217;t interpret &#8220;it&#8217;s not stopping&#8221; as meaning that it&#8217;s simply not coming to a stop while I&#8217;m watching it, rather than it will not come to a stop over a much longer period of time.  A key in all this is the identification of friction as a force and not some inherent property \u2014 that sometimes requires some mental untangling.  You have to be sure you&#8217;ve done that for a successful misconceptionectomy.<\/p>\n<p>Plus, we know that the earth is slowing down as it trades angular momentum with the moon.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>You need to a flashplayer enabled browser to view this YouTube video You have to do this with a rotating system because of space considerations and I think the globe is really neat, but \u2026 I have to pick nits &hellip; <a href=\"http:\/\/blogs.scienceforums.net\/swansont\/archives\/9328\">Continue reading <span class=\"meta-nav\">&rarr;<\/span><\/a><\/p>\n","protected":false},"author":2,"featured_media":0,"comment_status":"open","ping_status":"closed","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[39],"tags":[],"class_list":["post-9328","post","type-post","status-publish","format-standard","hentry","category-physics"],"_links":{"self":[{"href":"http:\/\/blogs.scienceforums.net\/swansont\/wp-json\/wp\/v2\/posts\/9328","targetHints":{"allow":["GET"]}}],"collection":[{"href":"http:\/\/blogs.scienceforums.net\/swansont\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"http:\/\/blogs.scienceforums.net\/swansont\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"http:\/\/blogs.scienceforums.net\/swansont\/wp-json\/wp\/v2\/users\/2"}],"replies":[{"embeddable":true,"href":"http:\/\/blogs.scienceforums.net\/swansont\/wp-json\/wp\/v2\/comments?post=9328"}],"version-history":[{"count":0,"href":"http:\/\/blogs.scienceforums.net\/swansont\/wp-json\/wp\/v2\/posts\/9328\/revisions"}],"wp:attachment":[{"href":"http:\/\/blogs.scienceforums.net\/swansont\/wp-json\/wp\/v2\/media?parent=9328"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"http:\/\/blogs.scienceforums.net\/swansont\/wp-json\/wp\/v2\/categories?post=9328"},{"taxonomy":"post_tag","embeddable":true,"href":"http:\/\/blogs.scienceforums.net\/swansont\/wp-json\/wp\/v2\/tags?post=9328"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
