Objective: Demonstrate the rotation of the earth with a Foucault pendulum
A Foucault pendulum is a long string pendulum with a heavy bob, which can be used to demonstrate the rotation of the earth. In this experiment, a pendulum 1.2 metres in length is used. The direction of its oscillations can be very accurately determined by projecting the pendulum’s shadow. For long periods of observation, any damping of the oscillation can be compensated for with the aid of an adjustable electromagnetic system to provide additional momentum.
