This collection of student activities contains problems dealing with waves and oscillations. Specific topics include masses on springs, pendulums, sound, and waves on a string. The activities include pictures and...

This lesson builds upon the previous two (Newton's Second Law and the First Law of Thermodynamics) by explaining that conservation of energy is not perfectly observed, in that energy is lost as it is transferred from...

This site from the Exploratorium provides a demonstration, using everyday materials, of the energy exchange between two coupled pendulums. The site provides a thorough description of how the two pendulums interact and...

This essay describes the influence that the pendulum had on Galileo's thinking and science. It also discusses the use of a pendulum to measure time. This is a part of The Galileo Project, an extensive web site on the...

This webpage, from Hyperphysics, describes a pendulum and provides a formula for its period. The page includes a calculator to obtain the period from the pendulum's length and the acceleration of gravity.
