That&#8217;s a very close value! How cool is that? But why are both Splash Mountain and FUJIYAMA&#8217;s actual top speeds slightly lower than the theoretical values? Why do you think that is?<\/p>\n<h2>External Forces at Play&#8230; but Why?<\/h2>\n<p>In rides like roller coasters or pendulums, &#8220;mechanical energy (kinetic + potential + elastic energy)&#8221; is almost always conserved. But let&#8217;s think for a moment. External forces, like the normal force (or tension in a rope), are at work on a roller coaster (or pendulum). So, shouldn&#8217;t mechanical energy NOT be conserved?<\/p>\n<p><img loading=\"lazy\" decoding=\"async\" class=\"alignnone wp-image-34250 aligncenter\" src=\"https:\/\/phys-edu.net\/wp\/wp-content\/uploads\/2020\/01\/4c6b0d20babac83068faf99d9515fce1.jpg\" alt=\"\" width=\"218\" height=\"201\" srcset=\"https:\/\/phys-edu.net\/wp\/wp-content\/uploads\/2020\/01\/4c6b0d20babac83068faf99d9515fce1.jpg 416w, https:\/\/phys-edu.net\/wp\/wp-content\/uploads\/2020\/01\/4c6b0d20babac83068faf99d9515fce1-300x277.jpg 300w\" sizes=\"auto, (max-width: 218px) 100vw, 218px\" \/><\/p>\n<p>What&#8217;s going on here? The secret is that the normal force and tension always act perpendicular to the direction of the object&#8217;s motion. The work done by a force perpendicular to the direction of motion is zero, so we only need to consider mechanical energy.<\/p>\n<p style=\"text-align: center;\">In the case of a roller coaster<\/p>\n<p style=\"text-align: center;\"><img loading=\"lazy\" decoding=\"async\" class=\"alignnone size-full wp-image-34251\" src=\"https:\/\/phys-edu.net\/wp\/wp-content\/uploads\/2020\/01\/c7b80d335aaa28806910324a263c17d9.jpg\" alt=\"\" width=\"288\" height=\"234\" \/><\/p>\n<p style=\"text-align: center;\">In the case of a pendulum<\/p>\n<p>While it&#8217;s difficult to calculate the exact magnitude of the normal force or tension, they do no work in this way.
