Exercise is a very difficult sport, not just a threat to Olympic athletes like five-year-old Simone Biles (so far). Physics is also challenging. Let’s look at something that looks simple, like a permanent paper.
There will be another type of image at all four female gym events: floor, bars, room, and cross. It is one of two alternatives that athletes can create midair. In physics, a flip is a rotation of the head and foot close to the imaginary line that runs through the waist of an athlete. For the second type of rotation, curve, consider the line that runs from head to toe.
Maybe it’s easier just to see them. The two videos were made in Python. (You can see the code Pano and Pano.)
The gymnasium can rotate at the same time – which is what makes the game fun to watch. In physics, we call this movement “physical flexibility”. But, obviously, people are not mature, which is why mathematical descriptions of such changes can be difficult. For the sake of simplicity, let’s not just talk about it.
There are three types of scrolls. There are designs, in which athletes keep their body straight. There is a pike, which bends about 90 degrees at the waist. Finally, there is a tuck, knees pulled to the chest.
What is the difference between the two?
Flexibility and Minutes of Inertia
If you want to understand the science of rotation, you need to consider the timing of inertia. I know it’s a strange word. Let’s start with an example of boats. (Yes, boats.)
Imagine that you are standing on a dock near a small boat just floating there, and you are not bound. When you put your foot on the boat and start pushing it, what happens? Yes, the boat took off – but it did something else. The boat too in a hurry as it moves. This change is fast and rapid.
