About Physics

Physics is science. One of the most fundamental scientific disciplines, physics investigates how matter and energy change over time.

Physics advances technology. Physics explains how electromagnetic waves encode information from a cell phone, how electricity in a computer chip is controlled by transistors, how a speaker produces sound with magnets, and how GPS calculates position.

Physics guides engineering. A knowledge of physics allows engineers to predict how their projects will behave. Physics helps them design, tinker, and experiment.

Physics speaks with math. Math is the language physics uses to understand and communicate the nature of our universe.



An organized notebook/binder and a scientific calculator is required.
I'm flexible about most other details, but I recommend:

graph paper: for graphing, charts, free body diagrams, circuit diagrams, ...
scientific calculator: TI-30XIIS is cheap and works well.
pen or pencil: I like these colored pens.


If you were absent, check in after class to see what you missed. If you need to make up an assignment, or have any questions come by my room after school.

About The Site

This site contains course notes for algebra based physics. I wrote it for my students, but it might be useful for anyone learning or teaching physics.

The source code is hosted on github. It's free to use under the MIT license.
The simulations were written in JavaScript, outputting to canvas or SVG.
For the math sections I used the typesetting library KaTeX.
Some physics simulations use the 2-D Physics engine matter.js.
