This exhibit uses fun ball games to allow children to experience the success of scientific inventions through interactive experiences, which require effort and cultivate good qualities to face and overcome difficulties. The exhibit mainly consists of a modeling platform, a serving device, and a track device, with two sets of four workstations. After visitors shoots the ball into the horn, it will roll on a specially designed track. If it successfully reaches the finish line, it will light up the central light bulb, bringing a sense of achievement and interactive experience. one Take out the ball from the pick-up port of the exhibit, turn on the serving device, throw the ball into the target horn, and make the ball enter the track device 2 along the horn Observing the motion trajectory of the ball on the track, waiting for the ball to roll to the endpoint, and observing the effect of the central light bulb being lit up. The motion of the ball on the track also involves the laws of center of mass motion and angular momentum of the particle system. The control of its motion trajectory requires the comprehensive application of these mechanical principles, and the design of the track is achieved through experimental exploration and calculation, demonstrating the scientific principles.
