This site from The Galileo Project of the Rice University provides a great look into the pendulum experimens of Galileo. Contains first-hand writings and examples of experiments along with links to additional information.

Kids love to ride the swings at the playground. The back-and-forth motion of a swing demonstrates the physics of a pendulum. In this experiment, you will investigate the factors that affect the speed and duration of a pendulum's swing.

Students examine the motion of pendulums and come to understand that the longer the string of the pendulum, the fewer the number of swings in a given time interval. They see that changing the weight on the pendulum does not have an...

Find out about Christiaan Huygens who built the world's first pendulum clock in 1656. The pendulum clock became the most accurate clock in the world for nearly 300 years.

Learn about prominent Dutch mathematician and scientist, Christiaan Huygens, whose work included early telescopic studies of the rings of Saturn and the discovery of its moon Titan, the invention of the pendulum clock, and other...

Provides a long list of physics formulas for easy reference.

Learn about the development of early clocks from the 14th through to the 19th centuries.

This resource presents a collection of experiments for the science classroom that focuses on physics concepts for Halloween. Activities include mirror ghost with a concave mirror, apple oscillators with pendulums, and a pumpkin pendulum....

In this interactive activity adapted from the University of Utah's ASPIRE Lab, students will investigate frequency in terms of trampoline jumps, pendulum swings, and electromagnetic waves.

In UCM, the net force called Fc is equal to mv2/r and is directed toward the center. This is demonstrated by an object that is suspended by a string and is moving in a circular path which makes a conical pendulum. In this experiment, you...
