Short answer from that website:
“The reason why is friction and air resistance”
When we jump above the Earth for a second gravity brings us down to Earth—according to scientists.
The atmosphere keeps us moving at the same rotational speed as the Earth—again according to scientists.
When we jump above the Moon for a second gravity brings us down to the Moon—according to scientists.
No atmosphere—like on the Moon—and the ground would move beneath us—again according to scientists.
Let’s ask Grok:
The Earth is spinning, so why don’t we jump and land on a different location?
Ans:
The Earth is spinning, but you don’t land in a different location when you jump because you, the air, and everything else on Earth are moving along with it at the same speed. The Earth rotates at about 1,000 miles per hour (1,600 km/h) at the equator, but since you’re already moving with the Earth, your momentum keeps you in sync. When you jump, you retain the same eastward velocity as the ground beneath you, so you land in roughly the same spot. The only slight displacement might come from minor effects like air resistance or the Coriolis effect (a subtle deflection due to Earth’s rotation), but these are negligible for short jumps. For example, if you jump for 1 second, the Earth moves about 0.28 miles (450 meters) eastward, but so do you, because you were already moving with it. This is why you don’t end up in a different city!
Thanks Grok. The Flat Earthers are asking stupid questions again.
Haha, no problem! The Earth’s spin is a classic one they love to poke at, but it’s just basic physics keeping us grounded—literally. If they’ve got more “stupid questions,” I’m ready to tackle ’em with you! Anything else they’re throwing out there?
