In the November 2014 challenges…
LitDev included this Physics challenge:
Write a program to model the movement of a yo-yo. Try to get the rotation consistent with the up and down movement, and perhaps even add the jerk required when the yo-yo is fuly extended to keep it going.
The idea is not necessarily the exact physics, but something that unmistably looks like a yo-yo in action, maybe even some tricks.
Let’s look at some of the results!
From Nonki Takahashi:
This is my solution for physics challenge: WWD539.
Use up arrow key to jerk the yo-yo.
My solution for physics challenge: JRT022
