(Unfortunately, I had to ride it twice just to collect the data.)<br \/>\nThe thing about thrill rides is that they aren\u2019t scary simply because they\u2019re fast. What makes them frightening is the way the acceleration acting on your body changes from moment to moment, creating <b>unexpected jolts and movements<\/b>. Our sense of balance is extremely sensitive to these sudden changes. You can find the acceleration and altitude data <a href=\"https:\/\/docs.google.com\/spreadsheets\/d\/1wuROYyPdmAnfPdmmWZtXbRg8SzrJW7g8MQ9-7zHzoJQ\/edit?usp=sharing\">here<\/a>.<\/p>\n<p style=\"text-align: center;\"><img loading=\"lazy\" decoding=\"async\" class=\"alignnone wp-image-39077\" src=\"https:\/\/phys-edu.net\/wp\/wp-content\/uploads\/2022\/01\/4beda6bec1abaf8365beb6381a154503.jpg\" alt=\"\" width=\"518\" height=\"788\" srcset=\"https:\/\/phys-edu.net\/wp\/wp-content\/uploads\/2022\/01\/4beda6bec1abaf8365beb6381a154503.jpg 1034w, https:\/\/phys-edu.net\/wp\/wp-content\/uploads\/2022\/01\/4beda6bec1abaf8365beb6381a154503-197x300.jpg 197w, https:\/\/phys-edu.net\/wp\/wp-content\/uploads\/2022\/01\/4beda6bec1abaf8365beb6381a154503-673x1024.jpg 673w, https:\/\/phys-edu.net\/wp\/wp-content\/uploads\/2022\/01\/4beda6bec1abaf8365beb6381a154503-768x1169.jpg 768w, https:\/\/phys-edu.net\/wp\/wp-content\/uploads\/2022\/01\/4beda6bec1abaf8365beb6381a154503-1009x1536.jpg 1009w\" sizes=\"auto, (max-width: 518px) 100vw, 518px\" \/><\/p>\n<p>The data showed that Big Thunder Mountain has a maximum vertical drop of about 9.9 m (9.6 m on the first run, and 9.9 m and 9.0 m on the second). The highest point is about 9.5 m above the loading area.<br \/>\nThe ride itself lasts about three minutes, which is shorter than Splash Mountain. What I found particularly interesting is that the ride makes <b>three separate \u201cenergy top-ups\u201d<\/b>, converting potential energy into kinetic energy as it goes.<br \/>\nIn other words, the coaster isn\u2019t designed to climb one huge hill and then make one enormous drop. Instead, it repeatedly climbs and descends a series of smaller hills. That\u2019s because the coaster\u2019s motor isn\u2019t running continuously. The energy initially supplied by the chain lift is effectively reused as the coaster races through the course.<\/p>\n<h3>The Maximum Speed You Won\u2019t Find in the Official Specs<\/h3>\n<p>Using the law of conservation of mechanical energy (\u203b), I calculated the maximum speed. The result was 13.9 m\/s, which works out to about 47.5 km\/h.<br \/>\nThis is probably not a figure you\u2019ll find in the official specifications, but it\u2019s still pretty fast! It may come as a surprise that a speed approaching the legal speed limit for cars on city streets is reached on such a relatively compact track.<br \/>\nThe data also shows some remarkably intense acceleration and deceleration. This is probably caused by the many small rises and dips along the track.<br \/>\nAll of this means that your body is being shaken around quite vigorously, and that seems to be one of the major differences between Big Thunder Mountain and Splash Mountain.<br \/>\nSplash Mountain creates its thrills with <b>one big drop<\/b>, while Big Thunder Mountain seems to create its thrills through <b>a continuous series of smaller jolts and rapid changes<\/b>. The data gives us a fascinating glimpse into how differently the two rides are designed, despite both being thrill rides.<br \/>\nIt\u2019s quite interesting to see that the underlying design philosophy can be so different.<br \/>\nI\u2019m also making the original data from both Splash Mountain and Big Thunder Mountain available here.
