The earth is spinning so fast, how can we not feel it

The reason why we generally feel dizzy on rotating objects is not because of the centrifugal force generated by the rotation of the object itself, but because the centrifugal force generated by rotation will be uneven and variable in magnitude and direction.

For example, if a person rotates in a circle, on the one hand, because the rotation cannot be absolutely uniform, the force changes, and on the other hand, because the radius of the person's rotation is relatively small, the centrifugal force on the outside and inside of the body is very uneven, so there is a strong feeling.

On the contrary, on Earth, the rotation of the Earth is quite stable, and the radius is large, and there is almost no difference in the magnitude of the centrifugal force experienced by the various parts of the body, so it is not felt.

It's like the bumps that people feel on a big boat are smaller than they do on a small boat, and that's the same thing.

The air is also rotating at the same speed. Everything you can see is spinning at the same speed. So there was no response.

We're used to it, and the pressure in our bodies is quite high, and we don't feel it.

This is because the earth is big, its angular velocity is fast, the linear velocity is slow, and what we can feel fast is the linear velocity. And when placed on a moving object, inertia is generated. So relative to the ground, we are stationary.

Because we are still relative to the earth, we don't feel it.

Relative motion and relative rest!!

We are relatively stationary relative to the Earth, so we don't feel anything.

We and the earth are one and the same, and the whole is relatively static.

You're sitting in a high-speed flying plane.

The windows are all covered, can you feel it?

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.

Because all objects on the earth are moving at the same speed as the earth's rotation, people and the earth are relatively stationary, so people can't feel the earth rotating.

The Earth's rotation speed of 1,667 kilometers per hour or 463 meters per second refers to the Earth's rotation speed at the equator.

Peculiarities of the rotation of the earth

Characteristics of the rotation of the earth: the rotational motion of the earth around the earth's axis, and the spatial position of the earth's axis is basically stable. Its northern end always points near the North Star, and the direction of the Earth's rotation is from west to east.

Characteristics of the Earth's revolution: the time required for one revolution is one year, about a day, and the rotation speed is faster at perihelion and slower at aphelion. The Earth's revolution produces seasonal changes in which the seasons alternate, and the average angular velocity of the Earth's revolution is about 1 degree per day.

The rotation of the Earth refers to the motion of the Earth around its own axis. The reason for the rotation of the earth is rotational inertia during its formation. The Earth's rotation speed is about 1,670 kilometers (1,040 miles) per hour.

The reason why we don't clearly feel the rotation of the earth is because we are on the earth, and we rotate with the earth. Our bodies, big finger aerators, objects, etc., all rotate with the earth, so we don't feel the rotational motion obviously.

However, we can observe the rotation of the Earth through some phenomena, such as sunrise and sunset. When the Earth's rotation causes the Sun to rise or set above the horizon, we are able to perceive a change in the position of the Sun. In addition, scientists are able to observe and measure the Earth's rotational motion by using precise measuring devices, such as gyroscopes.

To sum up, we do not feel the rotation of the earth because we rotate with the earth and the rotation speed of the self-dispatch code is relatively slow, so there is no obvious feeling.

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.
