What is a nutrition?
The word derived from the Latin nutare meaning to nod. It means nodding, swaying or rocking movement in the axis of rotation. Rotation can be a symmetrical object such as a bullet in a flight or a gyroscope. Planets also have a zero in the axis of rotation; The country's urgent was first discovered by a British astronomer in 1728. Precession is the term for the elliptical orbit of the Earth's axis point as it spins; Sometimes he points to Polaris as a star star and sometimes towards Vega in the constellation Lyra.
Earth's equatorial mass monitors this precession orbit in the seasons and orientation, and subsequently the Earth seems to fluctuate on its axis. Other planets also have such a zero. Astronomers calculate the nutritions of other planets according to the setting of the calculation formulas to find precise coordinates and obtain the repair of the objektu in the sky. None of the objects in the sky is in a fixed position from day to day. Well -known patterns forces are calculated in determining the exact location on that day.
gyroscope is similar to the toching peak of the child; As long as it spins quickly, it can remain well prepared at its small point in contact with the ground. When the upper part begins to lose speed due to friction of air and loss of momentum, it begins to fluctuate and eventually fall. When the peak turns quickly and stands straight, it is a precession display that turns around the vertical axis. Gravity is in suspension with horizontal pull due to the torque of the momentum of momentum in the precession. When the upper part begins with the slowing vibrations with small nodding from the perfect vertical position, it is the display of nutrition.
The tidal forces of the Sun and the Moon on Earth are the main sources of its continuously changing location, causing the axis of the Earth axis. The moon has the largest move,Because the Earth cycles coincide with the precession of the orbital nodes of the Moon. However, the simple mechanics of the rigid body of the illustration of the gyroscope does not take into account the deformation of the Earth, which is not perfectly smooth, nor the move from other planets, which also cause deviations of the matrix.
