HyperPhysics

The HyperPhysics website is a rather intriguing site where visitors can examine thematic segments in order to learn about dozens of physics-related concepts, such as atomic mass units, Avogadro's number, and acceleration.Hosted by the Department of Physics and Astronomy at Georgia State University, the site offers visitors the ability to join a live study group in order to share information and problems related to physics. Visitors can also use the list on the right-side of the page to look for specific topics of note. Clicking on each of these topics will bring up a definition of each term or topic, complete with graphs, diagrams, and in some instances videos. People with a sense of whimsy and fun will appreciate the "crushing Coke can" video as it is illustrative and edifying.
