Fun Turntable
★Exhibit Content: Coriolis force, inertia, centrifugal force ★Interaction: Electromechanical interaction ★Operation: Press the button. Once the rotating platform starts spinning, pick up the ring and place it on the track. Adjust the direction and release the ring, then observe the motion of the ring on the disc. ★Exhibit Description: The exhibit consists of a rotating platform, small rings, and small balls. After the participant presses the start button, the rotating platform will spin continuously. The rotation of the platform affects the path of the ring moving on its surface. The speed at the outer edge is faster than near the center, so the movement of the rings placed at different positions on the platform will be different. The participant presses the button; once the rotating platform starts spinning, they pick up the ring and place it on the track, adjust the direction, release the ring, and observe the motion of the ring on the disc. ★Scientific Principle: For an object in circular motion, due to its own inertia, it always tends to fly off along the tangent direction of the circle. When the net external force suddenly disappears or is insufficient to provide the centripetal force required for circular motion, the object will move gradually away from the center (when the net external force is 0, the object maintains its original velocity and moves in a straight line at constant speed). This phenomenon is called centrifugal phenomenon. The reason the object does not fly out is that the centripetal force continuously pulls the object onto the circular path, keeping its distance from the center constant. Once the centripetal force suddenly disappears, the object flies off along the tangent direction, moving farther and farther from the center.

★Exhibit Content: Coriolis force ★Interaction: Electromechanical interaction ★Operation: Press the "Start" button, rotate the turntable, observe the change in the shape of the belt, and think about what forces act on the belt? ★Exhibit Description: This exhibit consists of a platform, rotating mechanism, operation buttons, etc. Through interactive display, visitors can understand the Coriolis force. Visitors press the start switch on site, and the pulley starts rotating; at this time, the belt is parallel. When visitors rotate the large disc, the two parallel belts gradually approach or move away from each other, and the Coriolis force phenomenon, which is different from ordinary inertial force and inertial centrifugal force, can be observed. ★Working Principle: When the disc rotates, the belt between the two shafts undergoes a compound motion of rotating around the shafts and moving with the disc. When the direction of the belt's rotation around the shafts is the same as the direction of the disc's motion, the belt between the two shafts bulges outward; when the two motions are opposite, the belt between the two shafts concaves inward. This is the result of the Coriolis force.
