Ugears: Pendulum, STEM Lab
The Pendulum is developed to serve as a learning tool rather than a puzzle.
Just like the rest of Ugear's collections, putting STEM-lab models together is fun and comprehensive: everything you need to build, learn, and discover comes in a box.
The model comes with QR-code to a Pocket Model's Study Guide with a creation story and mechanism design as well as engaging and interesting tasks.
The Pendulum is a stylised educational model, an interactive study guide to the mechanism, only for learning its essentials and principles of working.
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 model has several means to control the frequency of oscillations: the weight of the pendulum bob, the vertical position of the weight on the pendulum, and the tension of the rubber band.
He described the property of the pendulum to preserve the consistency of the oscillations.
The first person to use a pendulum in a mechanical clock and ensure a steady rate was a Dutch physicist Christiaan Huygens back in the 17th century.
In the musical sphere, metronomes that have pendulums as their chief constructional element, help musicians practice playing to a regular tempo.
Pendulums are also used in geological surveying, seismography, sports, and laboratory research in mechanics and physics.
