collision detection

What happens when two circles collide in a p5.js canvas? In this video, I examine the math and implement idealized elastic collisions in a JavaScript physics simulation. This video supplements the Nature of Code book series in Chapter 6 which uses 3rd party physics libraries to handle collisions rather than a direct implementation.

Elastic Collisions

I love all things random and chance so why not make a Plink simulation with the matter.js physics engine and p5.js!
