> We are going to focus on the two types of dry friction: static and kinetic. "dry friction"... As I remember the story, someone was trying to replicate Arrheniius's equipment and results. The results weren't matching, until they took the equipment to an outreach event... where it got covered with greasy fingerprints. Turns out, it's Arrheniius's law of large objects sliding on pig fat. We actually now understand fri…

I just completed my two year project to build an online website to pair with my 11th grade physics classes. I hope it can be a resource for those learning and teaching physics. I've got some free time this summer so let me know if you have any advice about what else to add.

In the Electrical Potential lesson, you have a super cool Scalar Field simulation. I noticed you were doing some tricks to get it to render quickly, like rendering at a lower resolution while animating. I do a lot of HTML canvas work, so I figured I'd take a crack at implementing something like it, to see if I could improve the render performance. Here's what I came up with: http://electrons.surge.sh • (Small Improve…

Earlier quoted context omitted.

My Coulomb's law simulation is classical only, no quantum physics. I hope it has some value in showing emergent phenomena. Electrons can just leave the atom, this is how static electricity works.

Something so obvious I guess I never realized. So when electricity moves, the nucleus stays still, and the electrons are what move?
