Human Yo-Yo
★Exhibit Content: Conversion between kinetic energy and potential energy ★Interaction: Mechanical transmission ★Operation: 1. Read the exhibit description board to learn about kinetic and potential energy conversion; 2. Stand on the soft mat area of the platform and grip the lifting rope handle; 3. Bounce up and down forcefully on the ground to activate the top yo-yo mechanism; 4. Follow the rope to move up and down, feel the conversion between kinetic and potential energy, and exit the interactive area smoothly after the experience. ★Exhibit Description: This exhibit is a large-scale mechanical interactive science exhibit, consisting of a square platform, four sets of metal support rods, a top wheel mechanism, lifting ropes, hanging balls, and safety limit protection components. It is a recommended exhibit from the PopsciCat Exhibit Store. Visitors grip the rope handle and bounce up and down on the platform, driving the top wheel mechanism. The wheel cooperates with the rope to retract and release, driving the hanging ball to move up and down. The exhibit is equipped with limit devices and protective soft mats to control the interactive height within a safe range, and through mechanical transmission, it truly demonstrates the complete process of conversion between kinetic and potential energy. ★Scientific Principle: The exhibit demonstrates the mutual conversion between kinetic and potential energy. The bouncing of visitors generates kinetic energy, which can be converted into gravitational potential energy during upward movement; during downward movement, gravitational potential energy is converted back into kinetic energy. When the rope is wound around the wheel, friction causes some energy loss. The downward pulling force and body weight of the visitor compensate for the lost energy, thus achieving continuous up-and-down reciprocating motion, allowing participants to intuitively understand the physical laws of energy conversion and energy loss.
