About Physics

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

Physics advances technology. Physics is behind all the different technologies in a cell phone. Physics explains how electromagnetic waves encode information between a cell phone and tower, how electricity in the computer chips is controlled by transistors, resistors, and other elements, how a phone's speaker produces changing waves of air pressure, and how a phone uses GPS to know its 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. It was written 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.
Math is represented with the typesetting library KaTeX.
Some physics simulations use the 2-D Physics engine matter.js.
