How to increase the speed of the Earth s rotation? How fast the Earth rotates

Kill the Moon, and the Earth's rotation speed will increase significantly, which is unbearably fast.

If you push the earth, it will raise the !!

The speed of the earth's rotation is set by God, and God will not change it easily. God will speed up when necessary.

It's the center of the earth that's more active, so it's going to be faster, hehe.

You're so funny.

You go and ask God, right? Maybe he has a way, but not manpower!

01 The rotation of the earth from west to east around its axis of rotation. Earth's rotation is an important form of motion of the Earth, with an average angular velocity of rotation of radian seconds and a linear velocity of rotation at the Earth's equator of 466 meter seconds.

02 In the 50s of the 20th century, it was found from the analysis of astronomical time measurement that the earth's rotation speed has seasonal cyclical changes, with slower springs and faster autumns, in addition to semi-annual cycle changes. The amplitude of the annual variation is about 20 25 milliseconds and is mainly caused by seasonal changes in the wind.

03 The movement of the earth is changing and extremely unstable. According to the study of the "paleoclock", the Earth and its rotation speed are slowing down year by year. For example, in the Late Ordovician period, which was 100 million years old, it took 412 days for the earth to revolve around the earth; By the Middle Silurian period 100 million years ago, there were only 400 days per year; By the Late Carboniferous period, 100 million years ago, there were about 385 days per year; 65 million years ago in the Cretaceous period, about 376 days per year; And now there are only days a year.

According to astrophysical calculations, it has been proved that the Earth's rotation is slowing down. Scientists interpret this phenomenon as caused by the tidal action of the Moon and the Sun on the Earth hundreds of millions of years ago in the Middle Devonian period, with a year of 398 days.

04 Scientists have long observed that the cause of this cyclical change is related to seasonal changes in the Earth's atmosphere and ice. In addition, the movement of materials inside the earth, such as the sinking of heavy elements and their concentration towards the center of the earth, the upward movement of light elements, and the eruption of magma, will affect the rotation speed of the earth. Apart from the rotation of the earth, the revolution of the earth is not a uniform motion.

This is because the Earth's orbit is elliptical, with a difference of about 5 million kilometers from its farthest point and its closest point. When the Earth moves from aphelion to perihelion, the closer it is to the Sun, the stronger and faster it is affected by the Sun's gravitational pull. From perihelion to aphelion, on the contrary, the speed of operation slows down.

The average angular velocity of the Earth's rotation is in degrees and the linear velocity of rotation at the Earth's equator is 465 meters and seconds.

It takes 23 hours and 56 minutes for the Earth to rotate around the Earth, but in recent years the Earth's rotation period has been slowly increasing (i.e., slowly decreasing), resulting in the need to adjust the global timer.

Pole shift is the movement of the Earth's axis of rotation across the Earth's surface, which is measured by treating the Earth as a fixed and unchanging system of reference coordinates, Mount Xiaosui (the so-called Earth-centered, Earth-Collision-Center-Geostationary Coordinate System (ECEF)), which changes by only a few meters.

There are two main reasons for pole shift, one is the result of the deviation of the Earth's axis from the axis of inertia, with a period of about 14 months. The other is caused by the seasonal operation of the atmosphere, which has a period of one year. There are other secondary reasons, and the amplitude of the pole shift is generally not more than 15 meters.

As a result of the pole shift, the latitude and longitude of the Earth change.

Precession is the precession of the Earth's axis of rotation relative to stellar space. The position of the equinox, relative to the stars that are fixed on the celestial sphere, moves westward along the ecliptic.

Typically, the amount of movement per year is:", i.e. 1 ° per yearThis process is slow but adds up from year to year, with the complete precession going through 25,765 years (called Platonic years) and the equinox receding 360° on the ecliptic

Earth's rotation speed:

Earth's rotation is an important form of motion of the Earth, with an average angular velocity of rotation of radian seconds and a linear velocity of rotation at the Earth's equator of 466 meter seconds.

The position of the Earth's axis of rotation on the Earth's body is constantly changing, and this change is called the Earth's pole shift, referred to as pole shift. In 1765, L. Euler proved that if there were no external forces, the axis of rotation of the rigid Earth would oscillate freely around the axis of shape, with a period of 305 sidereal days.

Reasons for the change in the speed of the Earth's rotation:

The conductivity of minerals in the deepest part of the mantle is much higher than that of the rest of the underlying mantle, which may be an important reason for the periodic changes in the Earth's rotation speed. 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. But scientists don't know exactly why this change occurs in the rotation period.

In the study, the researchers simulated the environment of post-perovskite in the Earth's interior, that is, about 1.3 million standard atmospheres, 2500 degrees Celsius, and measured the conductivity of post-perovskite in this state, and found that the conductivity of post-perovskite layers is 10 to 1000 times that of other parts of the lower mantle.

The average angular velocity of the Earth's rotation is in degrees and the linear velocity of rotation at the Earth's equator is 465 meters and seconds.

Except for the North and South Poles, the angular velocity of rotation at all points on Earth is 15° hours.

The linear velocity of the Earth's rotation, the equator is the maximum, and it becomes smaller and smaller from the equator to the poles, and the poles are zero.

It is known that the latitude of a point on the earth's surface is , the radius of the earth is r, and the linear velocity of the point is v, then v=2 rcos 24, if the altitude above a point on the ground (latitude is h) and the rotation velocity of the geostationary satellite is u, then u=2 (rcos +h) 24.

The linear velocity of the parallels with the latitude value of is v=1670cos km h.

The Earth's rotation speed is calculated, the Earth's equator is l=2 r=2 The circumference formula of the circle), the Earth's rotation is 24 hours, v=l t=40192km 24=Definition of velocity – distance divided by time), so the Earth's rotation speed is.

Direction: from west to east.

1) Looking down from the North Pole: Rotates in a counterclockwise direction.

2) Looking down from the sky over Antarctica: Rotate in a clockwise direction.

3) The direction in which the east longitude increases and the direction in which the west longitude decreases is the direction of the earth's rotation.

The Earth rotates from west to east around its axis of rotation with an average angular velocity of 15 degrees per hour. At the Earth's equator, the linear velocity of rotation is 465 meters per second. The earth rotates from west to east around the axis of rotation, and the average angular velocity of the bridge is 15 degrees per hour.

At the Earth's equator, the linear velocity of rotation is 465 meters per second. The earth revolves. The orbit is elliptical, the orbit has a half-length diameter of 149597870 km, the eccentricity of the orbit is eccentricity, and the average orbital velocity of the revolution is km per second.
