Which Is Lighter, Which Is Heavier
★Exhibit Content: Intuitively experience the gravity differences of different planets, and learn about the gravity of the eight planets and the moon. ★Interaction: Pure mechanical manual interaction. ★Operation: 1. Pull the rope at the corresponding planet position; 2. Observe the pulling feel of sandbags of equal mass under simulated gravity of different planets; 3. Compare with the Earth reference group to feel the difference in gravity of each planet. ★Exhibit Description: This exhibit is an astronomy-themed pure mechanical interactive exhibit, consisting of a curved operation console, a background graphic display board, 8 sets of fixed pulley mechanisms, and sandbag components of the same size but different weights. The exhibit features 8 simulated planet units: Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, and Neptune. Using the Earth sandbag gravity as a reference, visitors pull the ropes to lift the sandbags, feeling the weight change of objects of equal mass on different celestial bodies through the difference in feel, and learn the gravity multiples of each planet relative to Earth with the help of the background board graphics. ★Scientific Principle: The volume and mass of each planet are different, and the corresponding gravitational acceleration varies; an object of the same mass experiences different gravity on different planets, resulting in differences in weight; Jupiter has the largest gravity, Mercury the smallest. The exhibit uses the weight difference of sandbags to simulate the real planetary gravity effect.
