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.\u003c\/p\u003e\n\u003cp\u003eThe model has an anchor escapement controlling the frequency of oscillations, a weight, a scape-wheel, gearing, rubber band, ratchet, and pawl reducing operation error. 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.\u003cbr\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eWhen and who invented it\u003c\/strong\u003e\u003cbr\u003e\u003c\/p\u003e\n\u003cp\u003eThe first study of the pendulum was implemented by Galileo Galilei, an Italian engineer in the end of the 16th century. 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.\u003cbr\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eUsage\u003c\/strong\u003e\u003cbr\u003e\u003c\/p\u003e\n\u003cp\u003ePendulums are mainly used in mechanical clocks as an element of a launch mechanism and the way to provide a steady rate. 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.\u003cbr\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eThe Pendulum is developed to serve as a learning tool not just a puzzle.\u003c\/strong\u003e\u003cbr\u003e\u003c\/p\u003e\n\u003cp\u003eJust like all the Ugear’s collections, putting STEM-lab models together is fun and comprehensive: everything you need to build, learn, and discover comes in a box including:\u003cbr\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eHigh-quality wooden boards with pre-cut details and other standard supplies.
