If you are using the pulley in a half-Atwood setup, lower the Ultra Pulley to a position where the string &#8211; connected to the cart on one end and a hanging mass on the other &#8211; is parallel to the track; in that position, the force exerted by the string is horizontal, i.e. does not have a vertical component.<\/li>\n<\/ul>\n<p class=\"wp-block-paragraph\"><a href=\"\/til\/2103\/\">Cart and Track System Troubleshooting and FAQs<\/a><br \/><a href=\"\/til\/1422\/\">Vernier Photogate (VPG-BTD) Troubleshooting and FAQs<\/a><\/p>","protected":false},"excerpt":{"rendered":"<p>A half-Atwood&#8217;s machine (also called a modified Atwood&#8217;s machine), with a cart, string, pulley, and hanging mass, is a common Newton&#8217;s Second Law and kinematics&#8230;<\/p>\n","protected":false},"author":100811,"featured_media":0,"comment_status":"closed","ping_status":"closed","sticky":false,"template":"","format":"standard","meta":{"_acf_changed":false,"footnotes":""},"categories":[],"tags":[3363,4007,379,2893,1944],"class_list":["post-15443","post","type-post","status-publish","format-standard","hentry","tag-b-spa","tag-dts","tag-spa","tag-track","tag-vds"],"acf":[],"_links":{"self":[{"href":"https:\/\/www.vernier.com\/til\/wp-json\/wp\/v2\/posts\/15443","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/www.vernier.com\/til\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/www.vernier.com\/til\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/www.vernier.com\/til\/wp-json\/wp\/v2\/users\/100811"}],"replies":[{"embeddable":true,"href":"https:\/\/www.vernier.com\/til\/wp-json\/wp\/v2\/comments?post=15443"}],"version-history":[{"count":0,"href":"https:\/\/www.vernier.com\/til\/wp-json\/wp\/v2\/posts\/15443\/revisions"}],"wp:attachment":[{"href":"https:\/\/www.vernier.com\/til\/wp-json\/wp\/v2\/media?parent=15443"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/www.vernier.com\/til\/wp-json\/wp\/v2\/categories?post=15443"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/www.vernier.com\/til\/wp-json\/wp\/v2\/tags?post=15443"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
