Transcript

[BELL RINGS] Welcome to another, now with haircut, video in Chapter 2, Nature of Code. What I have done so far, using the classical laws of motion, classical mechanics, force equals mass times acceleration, I have implemented a system where mover objects can receive forces as vectors and have those forces control how they move about a canvas in p5....
