Here are some resources to help in your study of classical mechanics, wave motion, and sound. The worked problems (not just final answers, but full solutions) can really help in figuring out the way to analyze a problem that leads to its solution. Even worked problems from a different textbook than the one for your class are handy!

If you have questions other than the types solved in these links, or you just want to find out more about physics and join a general discussion, try dropping in on the "Physics for Society" Discussions! Messages for different areas can be found in specific rooms, and a general physics discussion is set near the Lobby. (Information on using Discussions! is available to help you get started. The "Log-on" button below will take you to member login.)
