Coding Challenge

Choo choo! In this challenge, I build on chapter 3 (Oscillating Motion) of the Nature of Code series and simulate a simple pendulum in p5.js via angular acceleration. https://thecodingtrain.com/challenges...

Timestamps:
0:00 Choo choo!! 2021 Coding Challenge!
0:43 Code! Drawing a bob and an arm.
1:08 Explain! How are we going to think about this?
2:55 Code! Add our main variables.
3:20 Explain! How do we figure out where the bob is? Trigonometry is the answer!
4:39 Code! Use the polar coordinates formulas we just worked out.
6:30 Code! Let's use angular motion!
7:55 Explain! What is the force of the pendulum? Trigonometry is the answer!
10:46 Code! Add the pendulum force.
12:04 Whoops! Correction on why we multiply by -1.
13:34 Code! Add -1 to the formula.
13:57 Whoops! I figured out some things that I never really understood.
14:24 Code! Correct the 3 step process.
15:32 Something doesn't feel quite right.
16:59 Explain! Angular acceleration relates to the arm length!
18:58 Code! Let's divide by length.
19:54 Code! You could add some damping.
20:21 Ideas! What could you do next?
