Device for studying the oscillations of a single pendulum.
A protractor graduated from 0 to 90 ° makes it possible to measure the amplitude of the oscillations.
A winding system makes it possible to vary the length of the thread in steps of 10 or 5 cm.
A centring device makes it possible to keep the pendulum permanently aligned with the zero when it is at rest, whatever the length of wire.
Holes on the model allow the storage of 3 balls.
