  • This simple yet extraordinary device is the genesis of modern-day clock. Galileo Galilei in 16th century observed how long it took any object suspended from a rope or chain (a pendulum) to swing back and forth. Later on, the mechanism of pendulum was used to build a mechanical clock.


    The Pendulum is an educational STEM model to help you understand the mechanism and principle of a pendulum. The pendulum is one of the basic and most reliable time measuring mechanisms. Its working principle is based on the model's constant amplitude oscillation under the force of gravity (weight) and potential energy (tension force) of the rubber band. The rubber band powers the mechanism of the model and compensates for the pendulum's oscillations' kinetic energy loss. The device is animated by means of gear unit with a windup wheel.


    The escapement mechanism controls the frequency of oscillations. Even the modern day mechanical clocks use the same escapement mechanism.


    The model has the provision for adjusting the length of pendulum and weight of the bob. You can vary the weight of the pendulum bob, the vertical position of the weight on the pendulum, and the tension of the rubber band and see how these things influence the oscillation of a pendulum.
