The direction of the earth's rotation and revolution
The earth's rotation and revolution were from west to east. Observed from the North Pole, the Earth's rotation and revolution rotated in a counterclockwise direction, while observed from the South Pole, it rotated in a clockwise direction.
Earth's rotation and revolution
1. About the eight planets and the earth: the eight planets water, gold, earth, fire, wood, Saturn, the king of heaven and the king of the sea around the outside; only the earth's creatures appear, warm gas, liquid water is by fate. The earth turned from west to east, and time began to change. 2. Day and night alternated, and the four seasons changed. It revolved around the sun, and the four seasons appeared. One day of rotation, one year of revolution. From west to east, the direction did not change. 3. Earth's characteristics: the equator is slightly bulging, and the poles are slightly flat. From west to east, time began to change. The north and south are meridians, forming equal circles relative to each other. The east and west are parallel lines, forming parallel circles alone; The equator is the longest, and the two poles are points. 4. The division of the eastern, western, northern, and southern hemisphere: 20 degrees west meridian, 160 degrees east meridian. The northern and southern hemisphere is divided into two parts, the equator is at zero latitude, the four seasons are warm, and the north and south are opposite. 5. Earth's five zones: Earth has five zones, all separated by four lines; tropical zone, polar zone is divided into cold and warm zone; cold and warm zone each has two, the five zones have uneven temperature. 6. Map direction identification: Map direction identification, put it in front of your eyes; North is south, left, west, right, east. It is easy to distinguish the standard map, but it is more difficult to distinguish the latitude and longitude net. The latitude points to the north and south, and the east and west are coiled. The polar projection map had a special orientation: for the northern hemisphere, the center was north and the surroundings were south; the north latitude was east and west, and the rotation was reversed. For the southern hemisphere, the heart is surrounded by the north and south; The south latitude circle is east and west, and the rotation is in accordance with the time.
The difference and connection between the earth's rotation and revolution
There were many differences and connections between the Earth's rotation and revolution: ** 1. The difference ** 1. ** Sports Center ** - The center of the earth's rotation was the earth's axis, and the earth rotated around the axis from west to east. - The center of the Earth's revolution was the Sun (to be precise, it was the common center of mass between the Earth and the Sun). The Earth revolved around the Sun from west to east along a certain orbit. 2. ** Period ** - The Earth's rotation took about 23 hours 56 minutes and 4 seconds, which was a sidereal day. If the Sun was used as a reference point, the Earth's rotation took about 24 hours, which was a solar day. - One revolution of the Earth took about 365.25 days (more precisely, 365 days, 6 hours, 9 minutes, and 10 seconds, one stellar year). 3. ** Phenomenon ** - The phenomena caused by the Earth's rotation included the replacement of day and night, local time (the difference in time at different altitudes), various movement and rotation phenomena caused by the gravitational force of the northern and southern hemisphere, and the law of life and rest. - The phenomena caused by the Earth's revolution included the changes of the four seasons, the changes in the length of day and night, the formation of the Earth's five zones (tropical, north-south temperature zone, and north-south cold zone), the changes in the position of the astronomical phenomena, and the growth patterns of creatures. 4. ** Movement Speed ** - The angular speed of the Earth's rotation was 15 degrees per hour, and the linear speed varied according to the latitude and altitude. For example, the linear speed of the equator sea level was about 465 meters per second. The height increased or decreased by 100 meters, and the linear speed increased or decreased by 26 meters. The poles were zero. - The average speed of the Earth's revolution was 29.79 kilometers per second. The orbit was an oval with a flattening of 1/60. The perihelion of the orbit was 147.1 million kilometers, and the aphelion was 152.1 million kilometers. The average linear speed was 29.78 kilometers per second, and the surface speed was 1.92×10 to the power of 14 square kilometers per day. ** 2. Contact ** 1. The Earth was rotating and revolving at the same time, and the two combined to produce complex natural phenomena on Earth. For example, due to the Earth's rotation and revolution, the day and night on Earth were not simply equal in length, but there was a seasonal change in the length of day and night. The ecliptic and equator angle (the intersection angle between the ecliptic and the equator was 23 degrees 27 minutes) was the angle between the Earth's orbit and the orbit of the rotation. The existence of this angle caused the rotation and revolution to combine to produce the phenomenon of the day and night on Earth, the uneven length of the day and night, and the change of the four seasons.

What are the novels about the earth's rotation?
Planet Escape was a sci-fi novel written by Love Fighting the Landlord. The Earth deviated from its orbit, and disasters continued. After humans entered the era of black technology evolution, they built spaceships to escape. The protagonist, Xiang Gan, was reborn before the disaster and wanted to take the Earth across the sea of stars. This book had a big imagination. It combined doomsday and space escape. The setting was interesting. The early stages were good, but the later stages were a little broken, but it was still a good sci-fi fodder. Compared to " The Three-Body Problem," it was easier to understand and more interesting. It also involved a lot of sci-fi knowledge. The author was a high school student when he wrote this book. Some people felt that this was a good apocalyptic novel with a higher standard. Although it had flaws, it was recommended as a four-star novel. " Cataclysm of the Earth " was a sci-fi novel written by Shi Mian. The universe had a mysterious void corridor. The supernova explosion did not destroy Earth but instead allowed life to evolve. The young man rose to power in the universe after growing up on Earth. There weren't many novels that were well written and complete. This book was worth reading. " In Naruto, the Beginning of a Quiet Soul Court " was a light novel by Old Tree at the Burial Mound, a derivative doujinshi novel. The main character, Teruya, was the mastermind behind the scenes, causing trouble in the Naruto World, as well as the elements of the Grim Reaper. The author's writing style was good, the characters were well created, the plot was unique, and the various elements were well integrated, but it might not be suitable for everyone. For example, some people might feel that it did not conform to their values. " Global Martial Arts Reputation Achievement " was a novel written by Meng Kun. Liu Qi had transmigrated to a parallel world of high-level martial arts. There was a reputation system that allowed him to exchange for everything, refresh achievements, and receive rewards.

This book was quite good and worth recommending. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
Comics about the rotation of the earth
"The Earth's Movement" was set in the 15th century in the Kingdom of P, which was under Christian rule. At that time, it was between the end of the Middle Ages and the middle of the Renaissance. This comic won second place in the 2021 Comic Awards. 2022 ", the 26th Tezuka Osamu Culture Award, and other awards. He also defeated works such as" Jojo Gospels "and" Monster No. 8." Its author, Yu Feng, was only 24 years old when he created it. The comic had a total of eight volumes and sold more than two million copies. It was about to be adapted into an animation by Madhouse. The main character of the manga, Raphael, had originally chosen to study Theology. He had a bright future ahead of him, but he loved stargazing. After communicating with the Earth Movement Theory's advocate, Hubert, he began to think about the Earth Movement Theory. The story revolved around the history of the Earth's movement (Heliocentric Theory). It was not about the legend of Copernicus, but the story of a group of nameless people. Through Raphael and other characters, the comic showed the glory of humanity in the process of people pursuing the truth under the rule of religion. Different individuals intertwined with each other when inheriting beliefs, paving the way to the truth.
Diagram of the Earth's revolution
The earth revolved from west to east, and its revolution period was one year. The Earth's orbit was an oval orbit, and the center was the common center of mass between the Earth and the Sun. During the revolution, the earth's axis remained tilted and the direction remained unchanged. The tilt angle was about 23 degrees and 26 minutes. In the northern hemisphere, around March 21 is the vernal equinox, the sun is directly at the equator, and the global day and night are equal; around June 22 is the summer solstice, the sun is directly at the Tropic of Cancer.(23.5° north latitude), the day in the northern hemisphere is long and the night is short, and the north of the Arctic Circle (66.5° north latitude) appears polar day phenomenon; Around September 23 is the autumnal equinox, the sun's direct point moves back to the equator, and the global day and night are equal; Around December 22 is the winter solstice, the sun is direct to the south tropics (23.5° south latitude), the day in the northern hemisphere is short and the night is long, north of the Arctic Circle (66.5° north latitude) appears polar night phenomenon. During the revolution, the distance between the Earth and the Sun changed. The closest point to the Sun in early January was the perihelion, and the farthest point from the Sun in early July was the aphelion. The direct sunlight moved back and forth between the northern and southern tropics. This movement caused the Earth's surface to receive different sunlight, resulting in seasonal changes and the division of the five zones (tropical, northern, southern, northern, and southern).

Earth's tilt angle and direction
The angle between the Earth's axis of rotation and the plane of its orbit was about 23.5 degrees. When the Earth revolved, the tilt of the Earth's axis remained unchanged, and the northern end always pointed near the North Star.
Current direction of forward and backward rotation of variable frequency motor
Under the control of the frequency changer, the direction of the current when the motor is reversed is as follows: When the frequency changer wants to realize the forward and backward rotation of the motor, it can "reverse" the direction of the output current internally. This is done by using software and electronic methods to reverse. In the case of the field control, it was not convenient to change the direction of the magnetic field by changing the exciting method (because the establishment of the magnetic field required time, and there would be a time difference if the panel was used for operation, and the field control required a certain amount of real-time output of the torgue). At this time, it could be realized by reversing the speed signal given by the terminal simulator, which could be understood as the reversal of the current on the "Armature" causing the corresponding magnetic field direction to change. By reversing in this way, you can achieve coherent control, but you have to choose a frequency changer with a variable frequency control to have this function. When the motor works in the braking state under the control of the motor, the direction of the speed of the motor and the direction of the current are opposite. At this time, it will generate electricity to the bus, causing the bus voltage to rise. It requires an additional brake unit and brake resistance to release the energy appropriately. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
