Yo-Yo Simulations - Small Basic Featured Programs

In the November 2014 challenges...

LitDev included this Physics challenge:

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.

From jalpc:

My solution for physics challenge: JRT022
