==Classical Physics==
Contributions by Anika Jones Fall 2022
Classical physics encompasses the theories of mechanics, electromagnetism and thermodynamics that help explain a large part of the everyday things that go on around us on a macroscopic scale, which predates Modern Physic theories of quantum and relativity that explains things that are on the smaller, microscopic level.
In classical physics, observations about things can be seen using the human senses. For example, Newton’s observation that gravity caused things to fall to the ground leading to his three physics laws that are still relevant today. Classical physics helps to answer the whys about the things that we observe and experience in the world around us, from the path of the sun in the sky to the reaction of boiling a pot of water.
Classical physics laid the groundwork for modern physics theories to understand those things around us that we can not see in the traditional way but observed behaviors that are happening on a microscopic level.

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).

History

Classical Physics predates 1900 physics theories that help us understand phenomena around us, all thanks to works of Sir Isaac Newton, Galileo Galilei, and James Maxwell just to name a few. From their observations and research, we have a better understanding of how and why things operate the way they do around us that led to technological advances that we enjoy today in making a way of life easier.

Without any fancy and high-tech equipment, these scientists use simple observations and equipment to build the foundation of physics as we know it today that has been proven over hundreds of years to still be valid. From Newton’s law that force is equal to mass times acceleration to Maxwell’s equation for electromagnetism. Without their contributions our world today would look a lot different.
