*[[Moving Point Charge]]
*[[Moving Point Charge]]
A moving point charge creates both electric and magnetic fields. As the charge accelerates or changes position, it alters the surrounding electromagnetic field, which can influence other charges nearby. This is the fundamental concept behind electromagnetic radiation and wave propagation. When many charges move collectively—such as electrons in a wire—this flow is referred to as electric current. This perfectly segues us into the next section of this page.
*[[Current]]
*[[Current]]
Current is typically measured in amperes and represents the rate at which charge flows through a surface. Although electrons carry the charge and move from negative to positive, conventional current is defined in the opposite direction: from positive to negative. This convention dates back to early scientific assumptions and remains standard in circuit diagrams and equations today.

Georgia Tech Student Wiki for Introductory Physics.

This resource was created so that students can contribute and curate content to help those with limited or no access to a textbook. When reading this website, please correct any errors you may come across. If you read something that isn't clear, please consider revising it for future students!

Looking to make a contribution?

  1. Pick one of the topics from intro physics listed below
  2. Add content to that topic or improve the quality of what is already there.
  3. Need to make a new topic? Edit this page and add it to the list under the appropriate category. Then copy and paste the default Template into your new page and start editing.

Please remember that this is not a textbook and you are not limited to expressing your ideas with only text and equations. Whenever possible embed: pictures, videos, diagrams, simulations, computational models (e.g. Glowscript), and whatever content you think makes learning physics easier for other students.

Source Material

All of the content added to this resource must be in the public domain or similar free resource. If you are unsure about a source, contact the original author for permission. That said, there is a surprisingly large amount of introductory physics content scattered across the web. Here is an incomplete list of intro physics resources (please update as needed).

  • A physics resource written by experts for an expert audience Physics Portal
  • A wiki written for students by a physics expert MSU Physics Wiki
  • A wiki book on modern physics Modern Physics Wiki
  • A collection of 26 volumes of lecture notes by Prof. Wheeler of Reed College [1]
  • The MIT open courseware for intro physics MITOCW Wiki
  • An online concept map of intro physics HyperPhysics
  • Interactive physics simulations PhET
  • OpenStax intro physics textbooks: Vol1, Vol2, Vol3
  • The Open Source Physics project is a collection of online physics resources OSP
  • A resource guide compiled by the AAPT for educators ComPADRE
  • The Feynman lectures on physics are free to read Feynman
  • Final Study Guide for Modern Physics II created by a lab TA Modern Physics II Final Study Guide
