Double Cone Climbing Up
★Exhibit Content: Gravity ★Interaction: Electromechanical Interaction ★Operation: Place the cone at the lower end of the track, release it, and observe the direction of the cone's movement. ★Exhibit Description: The exhibit consists of a double cone and an inclined track. When the cone is placed at the lower end of the track, it will surprisingly roll up along the track. ★Scientific Principle: What is the secret? Careful observation reveals that the cone rolling up is only a surface phenomenon; in fact, during the rolling process, its center of gravity changes from high to low. The inclined track is arranged in a V shape, 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; 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 at the lower end of the track, it rolls up along the track. This is the secret of the cone rolling up. In a gravitational field, objects are subject to gravity and always move according to the principle of lowering the center of gravity for stability. The principle of 'lowering the center of gravity for stability' is widely applied in fields such as automobiles and aviation.

★Exhibit Content: Gravity ★Interaction: Electromechanical Interaction ★Operation: 1. Place the cone at the lower end of the track, release it, and observe the direction of the cone's movement. 2. Turn the handwheel to adjust the opening angle of the track and observe the direction of the cone's movement. ★Exhibit Description: The exhibit consists of a double cone and an adjustable inclined track. When the cone is placed at the lower end of the track, it will surprisingly roll up along the track. ★Scientific Principle: What is the secret?
