Ball and Feather (Free Fall in Vacuum)
★Exhibit Content: Vacuum, Gravity ★Interaction: Electromechanical Interaction ★Operation: Visitors press the start button, the transparent tube rotates and changes direction; observe the entire process of the ball and feather falling. ★Exhibit Description: The exhibit consists of a cabinet, two high-transparency vacuum glass tubes, a control console, a protective cover, a vacuum pump, and an electrical control system. It is a recommended exhibit from the PopsciCat Exhibit Store. The exhibit features two transparent tubes simultaneously: one retains air, and the other is evacuated to a vacuum environment. When visitors press the button, the device flips the glass tubes, and the ball and feather inside are released to fall simultaneously. In the tube with air, the feather falls slowly due to air resistance; in the vacuum tube, the ball and feather land almost simultaneously. This visually compares the effect of air resistance on falling motion, reproduces Galileo's classic falling body experiment, and is suitable for science and technology museums and campus science museums to conduct physics teaching related to gravity and free fall, helping students intuitively understand abstract physics concepts. ★Scientific Principle: An object that falls from rest under the influence of gravity alone, without air resistance, is said to undergo free fall. Near the Earth's surface, there is a constant gravitational field. When air resistance is not considered, free fall is uniformly accelerated linear motion, and the acceleration of fall is independent of the object's mass. In real environments, air resistance exists. The feather experiences relatively greater air resistance and falls much slower than the metal ball. In a vacuum environment, air resistance is eliminated, so the ball and feather have the same acceleration and land simultaneously. This verifies the law of free fall, breaks the everyday intuitive misconception that heavier objects fall faster, and helps visitors develop rigorous physical thinking.
