The earth is spinning, why don t people get dizzy?

Everything on Earth, including the atmosphere, rotates with the Earth. Therefore, people themselves will have a rotational inertial force (relative to other celestial bodies in space), plus the earth's gravity, to cancel out the rotational centrifugal force, so people are very inertial with the rotation of the earth, but once there is a problem with the earth, then the change of the force on people is like an external force, so that people produce another kind of acceleration, people will feel uncomfortable, such as **. Another example is the moment when a person just gets in the car

What the? The earth is spinning, and I'm starting to get dizzy when you say that.

It is recommended that you run in the direction of the earth, if you don't get dizzy, it means that you are running as fast as the earth, and you can sign up for the Olympics. No one will ever break your record.

Because people are always rotating with the earth, just like when we are riding a car, we may lean back when the car first starts, but when the car is driving smoothly, we are also telling the car to move forward at the speed of the car. The reason why people don't get dizzy on the earth is because we are rotating with the earth, and we and the earth are relatively stationary. So we won't get dizzy!

Physically, because the acceleration is small.

Coupled with the factors of biological evolution, man has adapted to this slight acceleration.

It's the earth that's turning, it's not you, you're dizzy.

Because the human brain is also spinning.

It's very slow, 24 hours to turn 360 degrees.

Because the angular velocity of all parts of the human body is the same

That is, relatively stationary

Relatively stationary. Because you're dead! ~

Only dizzy people say that the earth is turning, while normal people are not dizzy and never feel that the earth is turning.

People are born to follow and adapt.

In fact, people have always been dizzy, but they are used to it. Just like a drunk person never says he's drunk.

Why is the earth spinning and people not fainting? The main reason why people don't feel the earth is rotating is that there is no reference object, and everything around you is also on the earth. The reason why we don't get dizzy is because our brain has the role of regulating balance.

1 The earth is turning, but man is not faint.

1.This is because although the earth rotates very fast, because there is no reference object to compare, people cannot feel that the earth is rotating rapidly, so people will not feel dizzy. It's like a ship sailing in the sea, but you don't feel the ship walking, because the vast sky as a reference is so far away from us that you can only feel the ship moving fast by looking at the water under the ship!

2.When the elevator moves and stops, you will feel uncomfortable, and walking also has a frequency, that is, there is also an acceleration change, but you don't feel discomfort when walking. This is because when the acceleration is small enough, it will not only enter the blind spot of nature, but also enter the blind spot of physiology.

The earth only rotates 15 degrees per hour, which is only half of the hour hand of the clock, resulting in the acceleration change caused by the rotation of the earth in the blind spot of physiology. In addition, I have adapted to it for a long time, which is also one of the reasons.

3.Because you are stationary relative to the earth, and the land you are standing on is large enough, the earth rotates very smoothly, and there is no reference to make you feel that the earth is rotating, so you don't get dizzy.

Addendum: If you want to feel dizzy, there must be factors that make your brain dizzy, right? What happened when you thought about fainting?

Either you feel like you're moving around you, or you're speeding up or slowing down very fast relative to the ground, as if nothing happened to you standing on the ground, right? So if you don't feel a strong change in the outside world, how can you get dizzy?

4.There are two times when we feel dizzy. 1. There are references that make us feel that we are in motion, look at the earth as a whole, and the only reference objects you can refer to are the stars and the sun in the sky, but the distance between friends and the sky is too far away, and you can't feel their movement, 2. The receptors in the ears shake (motion sickness is it), but they don't shake when they move at a constant speed, and they can't do either, so they don't get dizzy.

1 The earth keeps rotating, why don't people faint?

The main reason why people don't feel the earth is rotating is that there is no reference object, and everything around you is also on the earth.

The reason why you can feel the car walking when you take the bus is that the trees, houses, and road surfaces on the side of the road are the reference objects of the car. And the Earth is so big that the only reference objects that can sense the Earth's rotation are actually the sun, moon, and stars, (which are not moving).

When you see the different positions they are changing, they are actually the reference of the earth turning.

The reason why we don't get dizzy is because our brain has the role of regulating balance. Why do people drink alcohol and get dizzy after a collision. It's not your brain that's shaking, it's the nerves that manage balance that go wrong, causing the brain to temporarily lose that ability.

Problem description: The earth keeps spinning, doesn't it feel dizzy itself? I sometimes feel dizzy, could it be caused by the earth?

Analysis: You won't get dizzy.

We feel dizzy because we have a balanced organ inside our ears, which is filled with a bodily fluid, and when the person turns, the fluid here also flows chaotically, and it is difficult for the body to grasp the balance.

The earth doesn't have such organs, so it doesn't get dizzy. (But if the earth is really a living thing, it may want to stop from time to time, but it likes us too much, so it can't bear to provoke this heart to stop, just hold on, and wipe out the lead.)

If you feel dizzy, it may be because you are too tired, rest more, but don't sleep for more than 10 hours, you will really get dizzy and faint all day.

How fast does the earth turn? How fast? Can you report a data to everyone? Soon?!

The reason why people don't have the feeling of being head-down when the earth rotates is because the feeling of head-down comes from the gravitational pull of the earth, and for people, no matter what state the earth rotates to, the gravitational force is directed to the center of the earth, that is, under one's feet.

In addition, when the earth rotates.

If a person does not move on the surface, then any part of the entire sphere of the earth is generally stationary relative to man, so man will not have the sensation of rotation.

Added: human sensations in addition to gravity, referential.

Sometimes it also comes from visual contrast and habitual cognition, for example, when a person sits on a train, the car starts slowly, and people look out the window at other stopped cars, most of the person's visual area is in the car area, and subconsciously use their own car box as a reference, which may produce the illusion that the car they are riding does not move and the car that has stopped starts. However, when the fixed building on the platform appears in a more prominent position in the line, in the habitual cognition, you will subconsciously remind yourself that it is not the platform that moves, but your own car starts, and this awareness will make you feel that the passengers themselves are moving with the car. Then, if you look at the earth in space that is close to the earth and has weak gravity, if the earth occupies most of the picture in the line of sight, and people are still in a state of weightlessness, for ordinary people, it will form a serious visual impact, resulting in illusions.

In short, people's feelings are more complex, and there are many factors that can affect people's feelings, in addition to environmental factors, physiological factors, and psychological factors.

Why don't you panic when you accidentally step on an ant? Ha ha.

Why does the Earth rotate so fast, but we humans don't feel dizzy?

The Earth's rotation around its axis of rotation from west to east has an average angular velocity of radian seconds and a linear velocity of rotation at the Earth's equator of 466 meter seconds. The average speed of the Earth's revolution is 100 million kilometers per year, that is, kilometers per second. The speed of the earth's rotation and revolution is so fast, why don't people feel dizzy?

It's actually quite simple, we know that it takes 24 hours for the earth to do one rotation. Think about how slow it is when a person stands still and asks him to rotate in 24 hours. Unless you're fast-forwarding.

By the same token, you can't see the minute hand on your watch. It's too slow for human perception. But if it's on a big enough clock, if you get a little closer, you can see the minute hand moving.

Another example is riding a merry-go-round. You can feel it spinning. But slow it down 60 times and your body won't feel it spinning.

Of course, the number related to its angular velocity is high compared to what we usually think of as a frame of reference, but it is still only equivalent to one revolution per day.

So in space, everything is moving, so when you talk about motion, you have to give a point of reference. "Earth's rotation" is an incomplete sentence. It lacks "from the perspective of the sun".

In the context of the solar system, the sun is the only thing that is stationary. If you want to operate in an orbit lower than the geostationary orbit (which is the case with most satellites, including the International Space Station), you need to operate in an orbit that is faster than the Earth's rotation. You can choose a higher altitude than a geosynchronous satellite, which will make your orbit slower than the speed of the Earth's rotation so that you can see that the Earth is rotating.

According to Newton's first law of motion, any object has inertia. Inertia is the property of an object to remain at rest or in a state of uniform linear motion: an object, as long as it is not affected by external forces, the original stationary will remain at rest, while the original moving object will maintain its original velocity and move in a uniform linear motion.

However, as long as the car is turned or accelerated and decelerated, the original driving and motion state of the car will be changed. When the brakes are struck, the girl slows down suddenly, and after being subjected to inertia, the girl will fall forward.

The motion of our Earth is similar to that of uniform motion: the Earth rotates all the time, and the average angular velocity of rotation is radian seconds, and the linear speed of rotation at the Earth's equator is 465 meters and seconds. But the Earth's rotation does not suddenly accelerate, slow down, or toss.

The earth does move, and we move with the surface of the earth, but because the earth is so big, living on the surface of the earth we don't have any sense of the rotation of the earth. In philosophical terms, you think you're not moving, but you're moving.

Sitting on the ground and traveling 80,000 miles, 80,000 miles, 10,000 miles, miles a day. What's next? It doesn't matter!

Anyway, I believe that most people know this truth from this "famous saying" of Grandpa Mao. Although we don't usually feel the world spinning, we can also find that the earth is rotating through some phenomena.

1.The phenomenon of alternating day and night.

The most obvious manifestation of the Earth's rotation is the alternation of day and night. If the earth does not rotate, then the earth will be like the moon, which can only face the sun on one side, so that the earth will always be half day and half night.

2.The phenomenon of stars rising in the east and setting in the west

Every day when the sun rises in the east and sets in the west, we will find that the stars are in different positions at different times, and the overall trend is from east to west, which is caused by the direction of the earth's rotation.

3.The phenomenon of water vortex

When we open the plug in the washbasin at home and put the water, we will find that the swirl of water rotates in a specific direction. This is due to geostrophic deflection forces, which are usually counterclockwise in the northern hemisphere and clockwise in the southern hemisphere.

4.Wear and tear of rails

No matter what direction of the railway, if there is no external force, it is usually worn out more on one side, the north-south track is usually worn on the east side, the east-west track is worn badly in the north hemisphere, and the south track in the south hemisphere is worn badly.

5.Riparian scouring phenomenon.

The embankments on both sides of many east-west rivers in China are often washed out more severely in the south of the riverbank, and some garbage and other floating objects are also mostly gathered in the south, which is also caused by the deflection force of the earth's rotation.

Because humans have adapted, and humans are moving in sync with the earth, humans don't feel dizzy.

There are three main reasons why the Earth rotates so fast that we don't feel it.
