Skillful Steel-Ball Control
★Exhibit Content: Gravity ★Interaction: Mechanical Interaction ★Operation: Place the steel ball on the far end of the iron rods, control the rods to close, and let the steel ball fall on the designated number point. ★Exhibit Description: The exhibit consists of a ball and two iron rod tracks. Place the iron ball on the two iron rods and control the opening and closing of the rods; you will find that the steel ball can move back and forth on the two rods. ★Scientific Principle: Objects in a gravitational field are subject 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. Under the action of the center of gravity, heavy objects can only roll from top to bottom, but this strange little thing in front of you disobediently rolls upward! In fact, it does not roll upward; due to the V-shaped groove, the center of gravity of the double-cone actually descends, so it is rolling downward.
