Review: A set of homework problems on energy, including friction. The problems are well-worded and very detailed solutions with diagrams are available. They are accompanied by computer experiment files, designed to be used with the Interactive Physics II software on a Macintosh computer. Even without the experiements the problems and solutions are detailed enough to be worthwhile. Chapter 12 deals with Conservation of Energy and Momentum and has some MPEG videos of collisions.

Review: A well done site by Bryan Luther of Concordia College, Moorhead MN. Online lecture notes for 3 lectures on Energy, including illustrations and examples. Click on "Next Lecture" at the bottom of the page to move forward.

Review: You need the Shockwave player to view these interactive experiments, but it's worth the time to download the free software. The "See-Saw Torque" and "Center of Mass" experiments apply to the concept of center of mass, and allow you to play around with adding and subracting masses from a system, and to see the effect on the center of mass. The "2-d Collisions" experiment is great. It allows you to view elastic, inelastic and magnetic collisions on a simulated flat or tilted air spark table. You can view the motion of the center of mass, and change the masses of the pucks. An excellent lab demonstration.

Review: An interactive learning site by the Prentice Hall publishing company, designed to supplement the Physics text by Douglas Giancoli. This site has a large number of good problems with animated illustrations and interactive hints and scoring.

Rating: 6
Review: A good site with full mathematical explanations of torque, moment of inertia, angular momentum, rotational inertia and kinetic energy of rotation. There are also some questions and answers at the end. The real-life application to sports makes for good examples.

Review: A full set of Powerpoint slides for every lecture. Extensive explanations with mathematics, illustrations and solved examples. Done in Powerpoint, but can be viewed through your web browser using the free Powerpoint Reader software, downloadable here.

Review: Just had to include this excellent applet! It shows the positon, velocity and acceleration vectors of a point on the rim of a body rolling without slipping. Done by the Virtual Physics Laboratory at National Taiwan Normal University.

Review: A great course site from UN at Lincoln. Two lectures on Simple Harmonic Motion, with solved examples and illustrations, and the worksheet with solved torque problems.

Rating: 7
Review: A very interactive tutorial/quiz on Simple Harmonic Motion, from the Department of Physics at the University of Guelph. (Which is in Ontario, Canada. I had to look it up.) It is in several parts, includes the mathematics, and has three interactive self-tests you can do.

Review: Another not-to-be-missed applet from National Taiwan Normal University. You can set the mass, k and b constants, frequency and amplitude of a mass on a spring, and watch it bounce up and down and then begin to move along the x-axis, tracing out a wave! This gang really knows their JAVA.

Review: Physics hypertextbook by Kenneth R. Koehler. Designed for students of biology or chemistry, but is mathematically based and covers generally what our class covers, plus some. Has lectures, questions and some interactive JAVA demonstrations.

Rating: 7
Review: Designed by Tom Henderson for Glenbrook South High School students (Glenview, IL), the mathematics of waves is not covered at our level. An excellent site for concept coverage, however, with great detail, illustrations, little interactive quizzes and some animations. Harmonics, fundamental frequency, and resonance are all covered in a 'sound waves' unit.

Review: Great discussion of fluids, including Bernoulli's Equation, lift and drag. Has illustrations and links to relevant ExploreScience Shockwave experiments. Unfortunately, we can't get into the assignment questions without a password.

Review: Another set of Powerpoint slide lectures, these from Physics 113 at UIUC. Two full lectures on fluids, with mathematics and illustrations.
