Gravity and Weight

概要

Gravity is like an invisible string that pulls everything in the universe toward each other. On Earth, this force is what keeps us on the ground and gives objects their weight. Just like magnets attract each other, every object in the universe attracts every other object - though we usually only notice Earth's gravity because it's so big! 🧲

詳細説明

例題

• When you jump on a trampoline, gravity is what brings you back down every time - you can't escape it! 🦘
• A bowling ball and a feather fall at the same speed in a vacuum because gravity pulls on all objects equally (though air resistance usually makes the feather fall slower) 🎳
• An astronaut floating in the International Space Station still experiences gravity, but they're actually falling around Earth so fast that they appear weightless! 👨‍🚀
