Why don t we feel the earth spinning?

Because of the principle of inertia, people move with the rotation of the earth, which is synchronized, so they can't feel it, just like when you sit in a car, you don't feel it when the car is driving at a constant speed, and you can only feel it when it accelerates or decelerates.

We are on the earth just like when we are on a ship, if there are scenery on both sides of the earth's orbit, we are more likely to perceive the rotation of the earth. But there is nothing near the earth, and although there are stars in the distance, they are so far away that it is difficult to feel that the earth is turning. As for the rotation of the earth, since we are carried by the earth to rotate, we don't feel that it is rotating.

But the rotation of the earth is real, do not believe it, please look at the phenomenon of the sun, moon, and stars rising in the east and setting in the west every day, which is the result of the rotation of the earth.

Because the earth is too big, and we are rotating with the earth, everything around us is moving with the earth, in physics this is called relative stationary, just like we take a train and a car, we and our passengers are speeding with the train and car, if we don't look out the window at the creatures, we will feel that we are not moving. That's the truth, back to the first sentence, the earth is so big that we can't see the creatures "outside the window", so we can't feel it.

When you sit smoothly in the car and your luggage is at your feet, you don't feel the luggage moving, but the pedestrians on the side of the road feel that your luggage is moving with you, why is that? This is because you choose yourself as the standard and feel that the relative position of you and the luggage has not changed, while the pedestrian chooses yourself as the standard and feels that your luggage is getting farther and farther away from him, in motion. In the same way, we live on the earth, and if we take you or this huge earth as the standard, the relative position of people and the earth has not changed, and they are stationary with each other, but if we take the moon or the sun as the standard, the position of the earth and them is changing and moving all the time.

This is a standard object, which we call a reference object.

There are three reasons why we don't feel the Earth turning, and here are the following, because we are so small. It's like we're on a speeding bus, and if we compare it with the scene outside, we're moving forward.

But if we compare it with the people around us, then we are stationary, from which we can understand that the earth is obviously rotating, but we can't feel its changes relative to the environment in the earth, so it shows how big the earth is and how small human beings are.

Introduction:

The second is the rotation of the water current, and it is often seen that some vortices will occur on the surface of some lakes, usually because the water plug on it may have been pulled out, or the water has accumulated to a certain point and then began to leak.

Then this vortex is related to the direction of rotation of the earth, depending on whether the time of the earth is clockwise or counterclockwise from the southern hemisphere, it depends on whether the vortex is clockwise or counterclockwise.

The third is to look at the garbage on the river, there is usually a little garbage floating on the river, and here we also want to accuse people of not protecting the environment, whether the garbage is blown to the lake by the wind, or directly thrown into it by man, it is our mistake.

The Earth rotates every 24 hours, and near the equator, its rotation speed is about 1,600 kilometers per hour. The Earth takes you around the stars in a huge circle day and night, but you don't feel its rotation. Because you and everything else (including the earth's oceans and atmosphere) rotate with the earth at the same constant speed.

We only feel it when the earth suddenly stops spinning

It's like riding in a fast-moving car and suddenly someone hits the brakes! Imagine riding in a car or airplane, and as long as the journey goes well, you can almost think that you are not moving. Jumbo jets fly at about 800 kilometers per hour, which is about half the speed of the Earth's equator.

However, when you are on such a plane, you will not feel like you are moving when you close your eyes. When a flight attendant pours coffee in your cup, the coffee also doesn't fly to the back of the plane. That's because the coffee, the cup, and you are all moving at the same speed as the plane.

If the car or plane is not moving at a constant speed, but accelerates or decelerates, the flight attendant will definitely spill your coffee, so be careful! We do not feel that the cause of the rotation of the earth is similar to the above events. If the Earth's rotation suddenly accelerates or decelerates, then you must feel it.

The constant rotation of the earth made our ancestors confused about the truth of the universe

They noticed that the stars, the sun, and the moon all seemed to be moving above the earth. Because the movement of the earth is not felt, it is logically deduced that the earth is stationary, and the whole sky revolves around the earth. The early Greek scientist Aristarchus first proposed the heliocentric model of the universe a few hundred years ago, when the world's great thinkers had adhered to the geocentric theory of the universe for centuries.

It wasn't until the 16th century that Copernicus's heliocentric model began to be discussed and understood, and although there were mistakes, Copernicus's model conclusively proved that in this world, the Earth rotates under the stars, on its own axis – and certainly in its orbit around the sun.
