Unpowered Cart
★Exhibit Content: Visitors manually assemble unpowered cars and place them on a wave-shaped track for racing, exercising hands-on skills and intuitively understanding inertia and basic car structure knowledge. ★Interaction: Electromechanical interaction ★Operation: 1. Read the exhibit description board to learn about inertia-related science knowledge. 2. Use the provided parts to assemble your own unpowered car. 3. Place the assembled car at the starting point of the track and release it. 4. Observe the car sliding along the wave track; the timing component at the finish line records the time for the car to complete the course. Compare the sliding times of different cars and think about the reasons for speed differences. ★Exhibit Description: This exhibit is a dual-track wave-shaped unpowered car interactive exhibit, consisting of a shaped display stand, two wave sliding tracks, car assembly parts, timing detection components, digital tube display modules, and an electrical controller. Visitors use the provided parts to assemble cars independently. After assembly, they place the car at the starting point and release it. The car relies on inertia to slide forward along the undulating track. A proximity switch at the end of the track triggers timing, and the digital tube displays the time taken for the car to complete the course. Visitors can repeatedly assemble and change parts to compare the sliding performance of cars with different structures. ★Scientific Principle: The exhibit primarily demonstrates the physical phenomenon of inertia. The property of an object to maintain its original state of motion is called inertia. After the unpowered car is released, no external force is applied, and it moves forward along the track relying on its own inertia, while being affected by gravity and friction during motion. The car's weight, wheel size, and center of gravity position all affect its sliding speed and distance. Through racing comparisons, one can intuitively feel how different conditions change an object's state of motion.
