Detail Page

published by the PhET
This is an interactive simulation on the topic of periodic motion.  Users can choose to work with one or two pendula to explore how the period of a pendulum is related to the length of the string, mass of the bob, and the amplitude of the swing.  Included is a "photogate" timer to measure the period accurately.  Friction and gravitational constant can also be controlled.

This item is part of a larger and growing collection of resources developed by the Physics Education Technology project.
