I’m Ken Kuwako, the Science Trainer. Every day is an experiment.<\/strong><\/span><\/p>\n

“Right now, I’m traveling through space at more than 1,000 km\/h thanks to Earth’s rotation.” Even if someone told you that, it probably wouldn’t feel real at all. That’s because <\/span>the Earth, the atmosphere, the oceans, and even our own bodies are all moving together at exactly the same speed.<\/b> It’s the same reason you don’t get left behind when you jump inside a speeding bullet train.<\/span><\/p>\n

One day, while reading through my students’ reflection sheets, I came across a fascinating question:<\/p>\n

“What would happen if Earth’s rotation suddenly stopped?”<\/p>\n

It was such an interesting idea that I decided to take it seriously.<\/p>\n

The short answer? It would be an extinction-level catastrophe.<\/b> Let’s break it down.<\/p>\n

How Fast Is Earth Actually Spinning?<\/h3>\n

The Earth completes one rotation every 24 hours, covering a circumference of about 40,000 km. That means the equator moves at an incredible about 1,700 km\/h (1,056 mph)<\/b>.<\/p>\n

The exact speed depends on your latitude. In Japan (around Tokyo, 35\u00b0 north), the ground is still moving at roughly 1,350\u20131,400 km\/h (840\u2013870 mph)<\/b>.<\/p>\n

That means we’re all cruising through space every day faster than a commercial jetliner\u2014without noticing a thing.<\/p>\n

Would People Really Be Thrown Through the Air?<\/h3>\n

This is where physics gets really interesting.<\/p>\n

According to Newton’s First Law of Motion (the law of inertia)<\/b>, an object in motion keeps moving at a constant speed unless an external force acts on it.<\/p>\n

If the ground suddenly stopped, our bodies would naturally try to keep moving at their original speed.<\/p>\n

Of course, friction and air resistance would immediately come into play<\/b>, so it wouldn’t simply be a case of everyone flying through the air at 1,400 km\/h. The reality would be far more complicated\u2014and far more devastating.<\/p>\n
