The earth is obviously spinning, so why can t we feel it?

Everything is running at all times, this is Newton's law.

A quote that previously people thought that the earth was forbidden, and this idea was wrongThe earth has been rotating, but there is a magical point, we can't feel the rotation of the earth, in fact, because it remains relatively still, let's take a closer look.

First of all, we want to talk about a concept here, relative stationary, which is actually also moving, but the speed between the two moving objects is the same, which makes the position between the two remain relatively stationary, it looks like it is one, there is no movement, and we all know that the earth has a rotation, every day is rotating, so there will be some countries at this time is night, while other countries at this time is day, and we who live on the earth are actually very small on the earth, We are also in motion, but we don't feel the movement of the earth because the autobiographical speed of the earth is very slow and the earth is very large, and we remain relatively still.

The area of the earth is very large, although it is very small in the universe, but in front of us human beings, the earth is very large, of course, there are many mysteries, at least the speed of the earth's movement is compared to the area of the earth, we can not feel the movement of the earth, because this process is too small, of course, it is also relatively small.

But when we feel that the earth is moving, it is likely that it has happened, so part of the reason why the earth can give birth to life is also because the rotation of the earth is very slow, and we remain relatively stationary so we can't feel it, otherwise it will cause a lot of interference to life on the earth, but if you feel that you are moving on the ground, you should pay attention, at this time it is likely to be a precursor to the occurrence of **, hurry up to find the problem of emptiness, after all, there are a lot of ** happening on the earth, It is a very dangerous thing for people.

As one of the eight planets in the solar system, the Earth is tirelessly revolving around the Sun, and it also rotates. As a human being on Earth, we can't feel the Earth turning, so how can we feel it turning? It's relatively simple, let's talk about the phenomenon of day and night.

While the Earth rotates and revolves around the Sun, we and other objects on the Earth also rotate with the Earth.

We don't feel it because our reference is the surrounding objects, but the other objects on the earth rotate with the earth. It's as if you feel the movement in the car and use the building outside the car as a reference.

Because the earth is inertial, and we humans are always in motion, we can't feel it.

Because we move with the earth, and the earth rotates so slowly, our senses can't feel that speed.

Because there is no reference. On a high-speed train at 300 kilometers per hour (with the windows closed), we don't feel the speed of the high-speed train, and we don't feel the speed on an airplane traveling at 700 kilometers per hour. If we think of the Earth as a "high-speed railway" in the universe, if there is a fast-moving scenery next to its orbit, we can easily feel the movement of the Earth.

But there's nothing like that up close.

We also don't have a way to put a nail in space as an absolute reference. As a result, it is only possible to rely on distant celestial bodies that appear to be stationary as references. In fact, those objects are by no means "nails in space" bent oaks, but because they are so far away, we might as well – and probably the only option – these distant stars as references.

Therefore, when an object is not affected by external forces, it will always remain in motion. This is also the content of Newton's first law.

Another reason why people can't feel the rotation of the earth is that the earth rotates too slowly and the angular velocity is too low relative to the volume of the earth. It takes a day to make a revolution, and it takes a year to make a revolution. There are some neutron stars in the universe that can rotate hundreds of times a second, and if the angular velocity of the Earth's rotation increases to a certain extent, people can feel the rotation of the Earth.

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.

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.

<> "When we take a boat or a car, it's easy to sense the movement of the car and the boat, but why don't we feel the earth turning at all?" The Earth rotates very fast, 30 kilometers per second around the Sun. The speed on the equator reaches 456 meters per second, and he travels 80,000 miles a day on the ground, which is really many miles faster than the speed of cars and ships!

When we sailed in the river by boat, the hull of the boat moved forward in the river, and the scenery on both sides of the river moved back, and we felt that the boat was moving fast. If you sail in the sea on a steamer, standing on the deck, the sea and the sky are the same, the white waves are surging, and the seagulls are chasing the boat, as if nailed to the side of the ship, at that time, you will feel that the boat is moving very slowly.

It turned out that when we took the boat in the river, because the river bank was relatively close to us, we saw the rapid movement of the two banks, and we realized that the boat was moving. When we sailed in the sea by steamer, the water and sky were vast, and the coast was far away, so my Wang Shou felt that the boat was very slow.

If the earth, the "big ship" of the universe, is like a ship in a river next to its orbit, it will be easy for us to perceive the rotation of the earth. However, the mass of the earth is too great, and only the distant stars can help us see the movement of the earth. But the stars are so far away from us that we don't feel the Earth turning at all for a short period of time, let's say minutes, seconds.

But don't forget that the sun, moon, and stars that we see every day are the result of the earth's rotation.

Because we move with the earth and have no reference. The reason why people can feel speed is because there are relatively stationary things that can be used as references, and if we can't see stationary references, we will not feel speed, and we think that we are stationary, and the things around us are rotating with the earth, and they cannot be used as references to help us perceive the rotation of the earth.

As we sailed on the river, we felt the scenery on both sides of the river quickly receding, and we realized that the boat was moving forward. But when we sail in the sea by boat, surrounded by the blue sea, and a few seagulls flying with the boat in the distance seem to be nailed to the sky, we have the illusion of stopping. So, the reason why we can feel speed is because there are relatively stationary things next to us that can be used as references, and if we can't see a stationary reference, we don't feel the speed, but think that we are stationary.

In the same way, because everything around us rotates with the earth, they do not help us to perceive the rotation of the earth, and only the stars nailed to the night sky can give us some inspiration, but they are so far away that we cannot see the movement of their positions in a relatively short period of time.

The rotation of the earth is a variable speed motion, and human perception of it depends on the movement of oneself and other objects in relation to oneself or proprioception. Since the angular velocity of ordinary objects around us is the same as our motion, we cannot judge the motion of the earth by them. In addition, the speed of the earth when it rotates is also very small, so people cannot judge whether they are rotating or not based on their own acceleration.
