If the earth doesn t rotate, how much will 100 catties of things become?

It hardly changes, because the weight is generated because of gravity, and gravity is due to the gravitational force between the earth and any object, and this gravitational direction is through the center of the earth, and the rotation of the earth is only offset by a certain part of the gravity that points to the earth's axis, so if there is an earth that stops rotating, then the mass of this thing does not change, and the gravity will become slightly heavier, and the change can almost be omitted...

Gravity doesn't change much, because at the moment gravity comes from the gravitational pull of the earth, and if the earth doesn't rotate, the gravitational force is still so great, because the mass of the earth and things hasn't changed.

Strictly speaking: it will be a little heavier, because the current attraction of the earth is divided into two parts: gravity + centripetal force; If it doesn't turn, the centripetal force is 0, and the gravitational force is equal to the attraction force, which will become slightly larger.

It won't be a brain teaser, like a pound of cotton or a pound of iron.

Does the earth still have gravity if it doesn't rotate?

The mass remains the same, the weight is only gravitational, and the centripetal force part is gone, but the centripetal force part is very small relative to the gravitational part, so it can be said that the gravitational force is almost unchanged.

If it is at the North and South Poles, it is still 100 catties If it is the equator = (1000 + centripetal force) Elsewhere, it will be calculated by vector In general, gravity = 1000n

The earth doesn't rotate anymore, and there is still power.

The weight of the earth is not constant, so is it increasing or decreasing? In fact, there are both increasing and decreasing aspects of the Earth's mass, but in general, the Earth's mass is decreasingIt's just that the extent of this reduction is not huge, so there is no need to worry about it at all. One might worry that if the Earth changes from one to the other, it may also mean that its orbit will also change, and it stands to reason that this is true, but the mass lost by the Earth is almost negligible compared to the total mass of the Earth.

But what about hundreds of millions of years from now? Obviously, no one can be sure, after all, there are too many chances. <>

In most people's subconscious, they probably think that the mass of the earth is immutable, because our daily lives do not change much because of the earthBut this is not the case, the mass of the earth is constantly changingAs mentioned earlier, the mass of the earth has an increase and a decrease in the mass of the earth, and there is an increase: the earth's absorption of space dust, meteorites hitting the earth, sunlight irradiating the earth, etc., some people question, does sunlight also have mass? From Einstein's mass-energy relationship, we can see that energy can be transformed into mass; Less:

Particles and energies escaping from Earth into space, such as hydrogen, helium, etc. <>

In fact, the increase or decrease in the mass of the Earth is insignificant in relation to the total mass of the Earth, but it can still be measured in tons. It is reported that the increased mass of dust absorbed by the earth through gravity and meteorite impact on the earth can still reach about 5 to 100,000 tons per year, obviously, this amount is not a small number for human beings, and as for the reduced mass, it is mainly reflected in the escape of hydrogen and helium, according to the calculations of scientists, the average atmospheric mass that escapes into space every year can reach tons, obviously, the loss is more than the gain. <>

Coupled with the various launchers developed by humans, although this mass is not much, it is also being lost, so the mass of the earth is decreasing.

If the earth stops rotating, we will not become heavier, but lighter. Because the Earth loses its gravity when it stops rotating, the weight of those who answer the question becomes lighter. Repentance.

It doesn't change, because the gravitational force that stops the rotation is constant for the Earth, so we don't get heavier.

No, the number of reeds on the earth stops rotating, the centrifugal force disappears, but the gravitational force does not change, so the objects on the earth will give people "just feel heavy, but not in actual excavation." ”

Just like when we are in a car, the vehicle accelerates suddenly, and we are affected by inertia to lean back, we who live on the earth have a similar inertia, and we are moving about 400 meters per second based on the current rotation speed of the earth.

If the rotation speed of the earth suddenly increases, assuming that the linear speed of the equator suddenly increases by 200 meters per second, then all living things and objects on the earth will directly become a "bullet" moving rapidly due to the influence of inertia.

Hitting an object at a speed of hundreds of meters per second could lead to extinction of humanity on Earth in an instant, unless it is in a very safe, soft place, tied with a very strong harness, and the air pressure inside is also kept stable.

Unless prepared, no life can survive the moment of the Earth's accelerated rotation, except for microbes. Sudden acceleration can also have an impact on the Earth's atmosphere, and the most violent global storm in history will appear, and everything will move and collide in the air, and eventually turn into a pile of rubble.

The most difficult disaster - increased centrifugal force: Assuming that humanity survives this catastrophe, the next step is not to return to a stable life, but to face a more serious disaster.

The rotation of the earth creates a centrifugal force, and this centrifugal force opposes the gravitational pull of the earth to form the current volume of the ocean. If the Earth's rotation speed increases, the centrifugal force will also increase, but the gravitational force will not change, and the oceans will expand in volume.

The more the speed of the earth's rotation increases, the larger the volume of the oceans, the vast majority of the earth's small islands and coastal cities will be submerged, and humans will have to build higher dams to keep the current land.

Fortunately, humans are also affected by centrifugal force and feel lighter.

If the earth rotates very fast, you may be able to jump a few meters casually, but if the rotation speed is too fast, if the centrifugal force is greater than the gravitational force, then everything on the earth will be thrown out, and if all the atmosphere is thrown into space, human beings will also usher in extinction.

In fact, whether the Earth's rotation accelerates or slows down, the oceans will be greatly affected, the global ocean layout will be reshaped, and it will be difficult for humanity to survive such a worldwide catastrophe.

The most insipid disaster - the acceleration of the diurnal change: a day of the earth is the time it takes for the earth to rotate by one day, and if the earth's rotation speed accelerates, then the time of the day will also be shortened.

Frequent sunrises and sunsets may affect the body's biological clock system, and then change the global biology, but this may also be a good thing, after all, Monday will pass quickly, shorter working days can be weekends, but weekends will also pass faster.

The body's current metabolism is very adaptable to a 24-hour day, and if the time of each day is greatly reduced, it may make it difficult for the human body to adapt and thus become more vulnerable.

If it were a slow increase, I don't think humans would be thrown out of the earth, but if it was suddenly rotated 10 times faster, humans might not be thrown out of the earth, but it would definitely cause a lot of chaos.

will not be thrown off the earth. Because the gravitational pull of the earth is so strong, even if the rotation is ten times faster, humans will not be thrown out of the earth.

I don't think we should be thrown out of the earth, after all, there is still the gravitational pull of the earth pulling us, so I don't think so.

The speed of the earth's rotation is not accelerating, on the contrary, the speed of the earth's rotation is constantly decreasing, that is, the earth is rotating more and more slowly, and the earliest time when the earth rotates a circle should be a little more than 18 hours and less than 19 hoursBut slowly today, the earth has a high life span of 4.6 billion years, and now the time of the earth's rotation is infinitely approaching 24 hours. <>

According to the law of conservation of energy, if an object itself is in a state of motion, there is no continuous work on it of a force, its own energy will gradually decrease, because there will be loss into an unusable energy, the same is true when the earth is rotating, the earth is a crystal composed of a lot of chaotic matter at the beginning of the birth of the solar system, and slowly cooled down after about 5 million years, these substances are originally rotating at high speedSo when these substances condensed together to reach a balance of forces, the earth was formed, because there was a solar system 5 billion years ago, and the earth 4.6 billion years ago. <>

At the beginning of the birth of the earth, the speed of rotation was relatively fast, because at that time, the energy contained in the chaotic matter itself was more fully reflected in the rotation of the earth, but now the energy contained in those substances is not so much, although this energy is so large that it is beyond our imagination, otherwise it is impossible for him to make the earth rotate for 4.6 billion years, but this energy is still gradually decreasingThis leads to a gradual decrease in the rotation speed of the earth itself, according to scientists, the future of the earth is really possible to 24 hours a day. <>

If a star says that it has the condition of accelerating its rotation, it is very terrible, because there is no unexpected influence of celestial physical strength, it itself will not accelerate its rotation, and its rotation speed will only become slower and slower under normal operation, because with the extension of time, when the original celestial body is formed, the energy it has is gradually consumed, even the energy of the sun we know is gradually decreasingThe sun is expected to burn out in 5 billion years, but that is far away from us, and we can't imagine it. <>

The problem of the sun, the problem of the earth, we really don't have to think too much, we should think more about our own problems, the earth and even the whole universe do not need human beings, or in other words, do not need the help of human beings, the whole universe and the whole earth are running very well, what we have to do is to adapt to the environment of the earth and the environment of the universe, and ensure our own safety in this environment, this is the most important thingBecause there were five generations of creatures before humans, and they disappeared no matter what happened, but the earth has always existed.

In fact, for us, in theory, human beings will never be thrown out of the earth, but it is undeniableIf the natural speed has been accelerating, then it will also lead to the centrifugal force greater than the gravitational force, the human being will be thrown out, of course, this possibility is almost minimal, so there is no such situation, in general, we must think about the problem from the following aspects. <>

1. Human beings are too small for us, and it is precisely because of this that they are almost insignificant in front of the earth, so it is impossible for human beings to be thrown out. In fact, it has to be said that human beings are indeed insignificant compared to the earth, and it is precisely because tiny seems to have become an inseparable part of the earth, so theoretically speaking, even if the earth's rotation speed is infinitely accelerated, then this rotation speed can only throw humans out of the earth unless it reaches an impossible number. <>

2. Theoretically speaking, the centrifugal force generated by the earth's rotation speed is greater than the earth's gravitational force on people, and only then can humans be thrown out. In fact, it has to be said that theoretically there is such a possibility, but the centrifugal force generated by the earth's rotation speed is greater than the earth's gravitational pull on humans before it can throw humans out, so theoretically this possibility is very small, so it can also be considered that there is no such possibility. <>

3. Theoretically speaking, the rotation speed of the earth can never reach the speed that throws humans out, so it is precisely because of this that humans may never be thrown out. In fact, I have to say that in fact, if human beings are to be thrown out of the earth, then this speed is beyond people's cognition, and in real life, the earth may never produce such a large rotation speed, and it is precisely because of this, in line with the facts, this possibility does not exist, so human beings will not be thrown out of the earth.

In fact, it has to be said that theoretically there is indeed the possibility of human beings being thrown out of the earth, but the natural speed of the earth must reach an impossible value, and it is precisely because of this that theoretically speaking, human beings will never be thrown out of the earth.

What would happen if the Earth's rotation suddenly increased to just one second a day, which means that the equator would move faster than 10% of the speed of light, and humans probably wouldn't hang up right away, and if we're lucky, it would last a few seconds.

Within a normal range, because the gravitational force is much greater than the centrifugal force, and with the earth as a reference, people and the ground are relatively stationary, so humans will not be thrown out of the earth.

Although the rotation speed of the earth is constantly accelerating, due to gravity, we do not feel that the earth is spinning, and we are not thrown out by the earth.

First of all, the rotation stops, and the mass does not change (the mass is not affected by the motion mode and speed of the object, of course, this is within a certain speed range, and its close to the speed of light is not discussed for the time being). No matter where you are in the world, it is still the same. It may be that it is gravity (that is, it is affected by the gravitational pull of the earth), which may be because the equator and the poles are different, because the rotation of the earth, the closer to the equator, the greater its centripetal acceleration.

So at the equator it will be larger than the original, and the closer you get to the poles, the less it will be affected, while the poles will not be affected.

In addition, the quality will not change. Gravity is the same as above, the equatorial stronghold will be smaller and smaller, and when the speed search difference is fast enough to a certain program, it may be thrown away from the earth. Hehe. Again, the poles remain unaffected.

In fact, if you have a little understanding, you will know that our earth is not a perfect circle, and the diameter at the equator is relatively large. It is because of the centrifugal force.
