Sine Pendulum
★Exhibit Content: Popular science on the principles of cycloid and sine curve ★Interaction: Mechanical interactive device ★Operation: Visitors operate the device to observe the black and white two-color balls driven by the cone device moving up and down. The trajectory of the balls forms a regular sine curve, allowing visitors to intuitively experience the formation process of a cycloid and the beauty of mathematical curves. ★Exhibit Description: The exhibit consists of a base, transparent protective cover, cone drive device, swing rod, and black and white two-color balls. It is a recommended exhibit from PopsciCat Exhibit Store. When the device operates, the cone mechanism drives the balls up and down. Through the movement trajectories of the balls at different positions, it intuitively demonstrates the principle that "when a circle moves along a straight line, a fixed point on its boundary forms a cycloid trajectory," helping visitors understand the relationship between the unit circle and the sine curve. It is suitable for science popularization displays in science and technology museums, youth activity centers, and mathematics science exhibition areas. ★Scientific Principle: When a circle moves along a straight line, the trajectory of a fixed point on the circle's boundary is a cycloid; the sine curve can be seen as the projection of the unit circle in a coordinate system. The exhibit materializes the abstract mathematical relationship through the movement of the balls, demonstrating the intrinsic connection between the cycloid and the sine curve.
