Lead your class in this exciting activity to learn more about motion and its importance. Pupils learn about a centripetal and why it is required to maintain a constant speed in a circulating moving mass. They apply the equation for...

Here's a resource ideal for independent learners who need extra reinforcement or would like to work ahead. These textbook chapters and practice problems cover many basic physics concepts, starting with potential and kinetic energy and...

Has your class wondered how fast a human could run or how high they are capable of jumping? Help them understand these concepts as they explore acceleration and use an accelerometer to make semiquantitative measurements of acceleration...

What is mu? Emerging scientists explore the coefficient of sliding friction, or mu, and apply its concepts as they complete activities in the interesting lesson. They measure the sliding friction between soles of their own athletic shoes...

Test the limits of gravity while encouraging full class participation with this thrilling lesson. Pupils investigate the meaning of work and how it is equivalent to energy. They explore the joule and apply it as a unit of work. They...

Lengthy discussion of Aristotle's theory of motion, its presentation by Aquinas, and its relation to Zeno's paradoxes.

From the Physics 2000 site, this page exemplifies their usual superb discussion of the concepts of heat, temperature, and absolute zero. Using an entertaining series of cartoon characters, the page gives a very understandable discussion...

Information about the interference of sound and its causes. Well-illustrated and good explanations of the concepts; part of a large hyper-textbook on various physics concepts.

Cherenkov light is explained here as the light emitted when a charged particle travels through matter faster than light would be able to. This would be slower, however, than the maximum speed of light, which occurs in a vacuum. "Explain...
