Does the earth turn, so why don t we feel it moving?

First of all, your question is wrong, you can feel the earth is rotating, first of all, the sun is the best example, it is because of the rotation of the earth to see the sun rising in the east and setting in the west, in fact, a fixed point on the earth on the equator because the rotation of the earth has to travel 40,000 kilometers a day, faster than the plane on the earth, but people can't feel that he is moving because you and the earth keep moving at the same speed, if you do it in a car, the road is very flat, close the windows, if you keep walking, you will not feel the car moving!

This is a problem of relative motion, the earth is moving in rotation, and you are moving with the earth, and there is no relative motion without relative displacement. For example, if you're on a train and there's a train next to you, and when you notice that the train next to you is moving backwards, you think that maybe the train you're on is moving forward, even though you don't seem to feel it's moving.

Turning from west to east, so that it travels day and night, and because there is a balance between the inertial force and the force, people and other substances maintain balance, so they do not feel its existence, when you suddenly come to the brake in the car and other places, you will feel it, this is because the inertial force is not balanced, so you can feel it.

The sun does not rise in the east and set in the west, the sun is there and has not moved, it is us who are moving, it is the earth that is turning, on a whim, the growth of plants is a chemical reaction, the soil, the air, the sunlight, the time. I was thinking that the soil contains everything except air, water, time, space, and soul. Why not separate everything that the soil encompasses, and if plant growth is a chemistry, is there a chemical formula that doesn't use the components of time.

Uncultured blind beep. It's just a whim.

Why don't we feel the earth turning? It turned out to be for this reason, it was amazing.

Analysis: First of all, your question is wrong, you can feel the earth is rotating, first of all, the sun is the best example, that is, because of the rotation of the earth, you can see the sun rising in the east and setting in the west, in fact, a fixed point on the earth on the equator because the rotation of the earth has to travel 40,000 kilometers a day, and the gear change is faster than the earth to shoot and get on the plane to attack such as but people can't feel that he is moving because you and the earth keep moving at the same speed, if you do it in a car, the road is very flat, close the windows, if you keep walking, You won't feel the car moving!

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 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.
