PhET Simulation: Pendulum Periods Name(s): Juan Bernal Todaro__________________________ Date:11/16/20_________ A swinging pendulum keeps a very regular beat. It is so regular, in fact, that for many years the pendulum was the heart of clocks used in astronomical measurements at the Greenwich Observatory. There are at least three things you could change about a pendulum that might affect the period (the time for one complete cycle): the amplitude of the pendulum swing the length of the pendulum, measured from the center of the pendulum bob to the point of support the mass of the pendulum bob Learning Objectives: Measure the period of a pendulum as a function of amplitude. Measure the period of a pendulum as a function of length. Measure the period of a pendulum as a function of bob mass. The website you need for this is Phet Simulations (University of Colorado) On opening the program, click on INTRO and Explore the simulation.
