Analysis of a crazy TikTok Jump. Original Video: https://www.tiktok.com/@overtime/video/7295905615719828778

You see a bunch of awesome (and sometimes weird) stuff online. In this case, it appears to be an attendant on a carnival ride doing a seemingly impossible jump. Check it out.

This appears to be on a ride that both rotates AND moves up and down. With a little bit of searching, it seems like it’s called TAGADA in Korea and the guy does a loose back layout while the thing rotates. Since the video was recorded by someone riding on the edge and the camera bobbles around, I made a frame corrected view.

Newton’s Laws in Accelerated Reference Frames

If we want to figure out what’s going on here, we need to think about Newton’s 2nd Law and how it works in different reference frames. First, we have the 2nd law. This gives a relationship between the net force on an object and that object’s acceleration.
