Relative Motion
★Exhibit Content: Popular science on the relativity of motion and the principle of reference frames ★Interaction: Interactive pendulum and moving platform installation ★Operation: Visitors first push the pendulum to make it swing, then slide the platform while the pendulum is in motion, observe changes in the pendulum's trajectory relative to the platform pattern, and understand how the reference frame affects judgment of motion state. ★Exhibit Description: The exhibit consists of a pendulum device and a patterned platform. By pushing the pendulum, comparing with the graphics on the platform, and observing the swing direction of the pendulum, when the pendulum is still moving, push the platform from the front, observe and understand how the pendulum changes relative to the platform pattern, thereby learning the physics knowledge related to relative motion and reference frames. ★Scientific Principle: "Relative Motion" is a classic mechanics interactive science exhibit for audiences of all ages. Through a swingable pendulum and a movable patterned platform, it transforms abstract physics concepts such as "relativity of motion" and "choice of reference frame" into intuitive and visible dynamic experiences. Visitors personally push the pendulum and slide the platform, and in observing the relative changes between the pendulum and the platform pattern, deeply understand: the motion state of the same object will present completely different results depending on the reference frame we choose. The principle of relativity of motion states that the motion state of an object is relative and depends on the chosen reference frame. When the pendulum and the platform move relative to each other, from the perspective of the platform (reference frame), the pendulum's trajectory will change with the platform's motion, intuitively demonstrating the influence of the reference frame on motion judgment.
