Very few people know that the mother Earth has the changeable speed of the movement around own axis that its speed depends on a width location.
Regardless of the fact that constant movements of our planet usually are imperceptible, the various scientific facts proved long ago that the mother Earth moves on the, strictly certain trajectory not only around the Sun, but also around own axis. It causes the mass of the natural phenomena observed by people daily such, for example, as change of time of day and night. Even in this second, reading these lines, you stay in the constant movement, the movement which is caused by relocation of the native planet.
Changeable movement
It is interesting that the speed of Earth is not a constant, for the reasons which scientists, unfortunately, till this time did not manage it is for certain known to explain, however, that each of centuries Earth slows down the speed of the usual rotation at a size, equal about 0.0024 seconds a little. It is considered that the similar anomaly is directly connected with the certain lunar attraction causing inflows and otliva for which and our planet also spends a significant share of own energy which "slows down" its individual rotation. The so-called tidal ledges moving as usual in the direction opposite to Earth course cause emergence of certain friction forces which, according to laws of physics, are the main braking factor such purse of a space system as Earth.
Of course, there is no axis actually, it is the imagined straight line which helps to make calculations.
In one hour, it is considered, Earth makes a revolution in 15 degrees. For how many she turns around around an axis completely, it is easy to guess: 360 degrees - for one day at 24 o'clock.
Day at 23 o'clock
It is clear, that Earth is wrapped around an own axis in 24 hours habitual to people - ordinary terrestrial day, to be exact - in 23 hours fifty six minutes and nearly 4 seconds. The movement happens steadily from the western part on east and in any way differently. It is easy to calculate that under such circumstances speed on the equator will reach about 1670 kilometers per hour, gradually decreasing at approach to poles where smoothly passes to zero. With the naked eye it is impossible to find the rotation made by Earth with so huge speed, together with people also all surrounding objects move. All planets of the solar system make similar movements. So, for example, Venus has much the smaller speed of the movement for this reason its day differs from terrestrial more than by two hundred forty three times.
Jupiter and planet Saturn making the full turn around an axis in ten and ten and a half hours respectively are considered as the fastest of planets known today.
It should be noted that rotation of Earth round its pivot-center - extremely interesting and unknown fact needing further fixed studying scientists of the whole world.
