This applet simulates the swinging of a pendulum and calculates its period.
Click anywhere in the applet to start the pendulum swinging.
Please note that this applet is not an accurate time-measuring device. The speed that this pendulum swings depends on the speed of your computer.
The period of oscillation T of a pendulum is given by:
where l = length of pendulum and g = acceleration due to gravity.
As the length of the pendulum increases, its period increases.
