Why does the Earth rotate? Why turn from west to east?

We know that almost all celestial bodies in the solar system, including asteroids, rotate according to the law of the right-hand rule, and the rotation of all or most celestial bodies is also the right-hand rule. Why? The predecessor of the solar system was a dense cloud, driven by a certain force that attracted each other, and this accretion process made the density gradually larger, which accelerated the accretion process.

On the one hand, the centripetal accretion accumulation becomes the sun, and on the other hand, the gas gradually develops into a flattened shape, and in the process of development, the potential energy becomes kinetic energy, and finally the whole thing turns. At the beginning of the rotation, there are those who turn this way, and those who turn that way, after a certain direction prevails, they all become one direction, and this direction is the right-hand rule that is now discovered, and there may be other solar systems that are left-handed rules, but in our solar system it is the right-hand rule. The energy of the earth's rotation** is caused by the eventual transformation of material potential energy into kinetic energy, which ultimately means that the earth rotates on the one hand and rotates on the other.

The rotation of the Earth does not stop, although there is acceleration, it will get smaller and smaller, and it will not reduce the angular momentum to 0.

If only the Earth-Moon system is considered, the deceleration limit is the synchronous rotation of the Earth-Moon due to the conservation of angular momentum, as in Pluto. This is the reason why the moon always has only one side facing the earth, but because the moon is small, the earth is large, and the moon's tidal effect on the earth is small, so the earth is not relatively stationary now, but one day it will still be, and then there will be no tidal action between the earth and the moon. But don't forget that there is relatively no rotation between the Earth and the Moon, but there is still a rotation relative to the Sun, so the Earth's rotation will not stop.

Some of my previous explanations were wrong.

Everything is in motion.

Not only rotation, but also revolution. The moon is the same, the sun is too, and so is the Milky Way. The direction of rotation of the Sun coincides with the direction of rotation of the planets of the solar system.

As for the determination of the east-west direction, it is to first have the direction of rotation, and then determine the thing. It's like using the axis of rotation to determine north and south.

The rotation is to allow people from different places to shine on the sun.

It's amazing

If I were to watch the Earth spin like that from space, I would have felt like a giant was pushing it.

In the subject of geography, we will learn the knowledge of the rotation of the earth, because of the rotation of the earth, so there are a lot of rotation meanings, because the earth does not shine and is not transparent, so the alternation of day and night is the meaning of the earth's rotation. In addition, the meaning of the earth's rotation also includes local time and regional time, so is the direction of the earth's rotation from west to east?

1. The direction of rotation of the earth is from west to east. The rotation of the earth means that the earth rotates from west to east around the axis of rotation. The rotation of the Earth is an important form of movement of the Earth.

During the first attack on the Earth's rotation, if the Earth's rotation is seen above the South Pole, then the rotation is clockwise; If you are looking at the Earth's rotation from the North Pole, the direction of rotation is counterclockwise.

2. The rotation of the earth is an important form of motion of the earth, the average angular velocity of rotation is in degrees and seconds, and the linear velocity of rotation at the equator of the earth is 465 meters and seconds. It takes 23 hours and 56 minutes for the Earth to rotate around and increases or decreases by 3 to 4 thousandths of a second every 10 years.

3. The rotation of the earth also causes objects that move horizontally in any direction on the earth to deviate from the initial direction of their motion. If the moving object is oriented in the direction of travel, the horizontal object in the northern hemisphere is biased to the right, and the southern hemisphere is biased to the left.

4. The reason for the deflection of the direction of motion of horizontal objects on the surface is that objects have inertia and try to maintain their own speed and direction. As mentioned above, the horizontal direction of the earth is based on the meridian and the parallel, the direction of the meridian is the north-south direction, and the direction of the latitude line is the east-west direction.

5. However, due to the rotation of the earth, the meridians and latitudes, which are the standard of north-south and east-west directions, are deflected with the autobiography of the earth. As a result, the horizontal motion of an object that really maintains the same direction is deflected relative to the direction on the earth.

The above is an introduction to whether the direction of rotation of the earth is from west to east.
