Mass point mechanics: (also real solids)
Explore Learning is a paid subscription-based site with interactive simulations (called Gizmos) in math and science for teachers and students, mostly at the high-school level. Layout and overall design are excellent, and there is ample help online. A 30-day free trial is available. The site has received several awards. Topics include collisions in one or two dimensions, harmonic motion, parabolic motion, and free fall. The Medien Server from the Universität Kaiserslautern contains university-level multimedia for use in classroom or distance learning. Mostly German and mostly restricted access (limited to registered students), although some are free. Quality is generally excellent, and MM is easy to use, although online help or documentation is limited. Some very good short video-clips and mostly non-standard material (relativity).
Frames of reference and special relativity / system of mass points / dynamics of rigid bodies Particle World, by Fredrik Karlsson, enables one to create applets in order to perform an almost arbitrary virtual experiment with a system of point masses moving in two dimensions. It is comprehensive, besides predefined situations allows one to build up several situations with springs, gravity, charges, and friction. A unique and very democratic feature of the site is that it allows users to add new systems to study, and provides the necessary tools for such a development. The collection of the contributions from others (as acknowledged authors) is also open for everyone connecting to the site. The Virtual Physics Laboratory, by Fu-Kwun Hwang, is a rather large but not a systematic collection of applets from several parts of physics, including topics
from mechanics. The material is sufficiently advanced, technically good and interactive to a certain extent. Some of the pages provide a concise explanation.
Flowing liquids and gases / mech. oscillation and waves "Aeronautics Resources", from the NASA Glenn Research Center, includes program versions for less and more advanced students. Many Applets can be downloaded and used out of Internet. In the part about Rockets and Kites there are Teacher's Guide and Lesson Plans. The Math and Physics applets page, by Paul Falstad, includes applets on "Oscillations and Waves” and “Acoustics". The page contains Applets with links to relevant physics. The material is at university level only, very useful for the presentation during lectures. All Applets, interactive with many parameters to change, deal with more ambitious physics than the other pages on the topic.
Nonlinear dynamics and chaos
The site to be recommended by us is “Introduction to Chaos and Nonlinear Dynamics” by Takashi Kanamaru and J. Michael T. Thompson.
Additionally to some further material concerning chaos and nonlinear dynamics it consist of a collection of over 20 Java-applets. To every applet there exists a text that explains what it shows, the mathematical background as well as a short instruction of what to do.

MERLOT recommendations (Highly rated materials not listed above, although many were recognized as quality items by the EPS reviewers.) Physics Illuminations is an online drill and tutorial program for kinematics, dynamics, and vector algebra developed by Ron Greene. Designed to provide students with conceptual physics instruction and practice outside of class, the materials include tutorials illustrated with animated java examples and graded practice quizzes with results recorded for the instructor. The Pendulum lab by Franz-Josef Elmer is an extremely thorough investigation of the dynamics of a pendulum, from the simple pendulum to the chaotic motion of the damped, driven pendulum. Virtual experiments can be performed, and an extensive set of hyperlinked notes explains the theory of the system. This material can be used for a wide range of student levels. HyperPhysics by Carl R. Nave is an extensive outline of physics, from classical mechanics through quantum and modern physics topics. Although this site does not use multimedia extensively, it’s creative, deep, and well organized use of hyperlinks makes it a powerful learning tool for introductory and intermediate physics students. Physlets, from Wolfgang Christian and co-workers, is an extensive collection of java applets for simulating physical systems. The power of these tools comes from the ease with which they can be scripted to simulate a wide range systems and the ability of the applets to share data. A single applet, Animator,
along with graphing and data table tools, can be used to cover most of classical mechanics.
