Why on earth can the earth keep turning? Who gave it the power?

As for the earth's rotation, it can be said that it has existed since its birth. Who provided this power?

Speaking of which, it goes back to the beginning of the formation of the earth.

The predecessor of the solar system is a dense cloud, which attracts each other under the drive of some force. This accretion process makes the density increase gradually and accelerates the accretion process. At first, the particles in the original solar nebula were in a chaotic state, and they rampaged, gradually changing the disordered state into an orderly state. On the one hand, they accumulate centripetally and become the sun. On the other hand, this gas gradually develops into a flat state. In the process of development, potential energy was transformed into kinetic energy, and finally the whole thing took a turn for the better. All kinds of celestial bodies rotate in the same direction because they all formed in the same solar nebula billions of years ago.

At the beginning of the turn, some turn this way and some turn that way. After a certain direction has gained the upper hand, it has become a direction, which is now the right-handed rule. There may be other solar systems that are left-handed, but in our solar system, it is the right-handed rule. The energy source of the earth's rotation is that the potential energy of matter is converted into kinetic energy, which eventually makes the earth rotate while revolving.

earth rotation

The earth rotates around its axis of rotation from west to east, with an average angular velocity of 15 degrees per hour. On the equator of the earth, the linear speed of rotation is 465 meters per second. All kinds of celestial bodies in the sky are reflections of the earth's rotation. The periodic changes of the earth's rotation mainly include annual cycle, monthly cycle, semi-monthly cycle and near Sunday and semi-Sunday cycle.
