PhET Simulation: Pendulum Periods
Name(s): Juan Bernal Todaro__________________________
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
There are at least three things you could change about a pendulum that might affect the
(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
the mass of the pendulum bob
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)
