Double Cone Climbing Up
Operation: Place the cone on the lower end of the track, release it, and observe the direction of the cone's movement. Function Overview: The exhibit consists of a double cone and an inclined track. When the cone is placed on the lower end of the track, it is surprising to find that the cone actually rolls up along the track. Scientific Principle: What is the secret behind this? Upon careful observation, you will find that the cone rolling up is only a surface phenomenon; in fact, during the cone's upward rolling, its center of gravity changes from high to low. The inclined track is arranged in a V-shape on both sides, with one end low and the other high. At the low end, the distance between the tracks is small, the fulcrum is close to the center of the cone, and the cone's center of gravity is high; while at the high end, the distance between the tracks is large, the fulcrum is close to the outer edge of the cone, and the cone's center of gravity is low. Therefore, when the cone is placed on the lower end of the track, it will roll up along the track. This is the secret of the cone rolling up. In a gravitational field, objects are subjected to gravity and always move according to the principle of lowering the center of gravity to seek stability. The principle of 'lowering the center of gravity to seek stability' is widely applied in fields such as automobiles and aviation.
