Nutation (from Latin nūtātiō 'nodding, swaying') is a rocking, swaying, or nodding motion in the axis of rotation of a largely axially symmetric object, such as a gyroscope, planet, or bullet in flight, or as an …

Nutation, in astronomy, a small irregularity in the precession of the equinoxes. Precession is the slow, toplike wobbling of the spinning Earth, with a period of about 25,772 years.

Those who have studied the gyrations of a spinning top will recall that, in addition to precessing, a top may nutate, or nod up and down (Latin nutare, to nod), the amplitude and type of nutation depending …

Dec 14, 2018 · Nutation and precession are the periodic and long-term motion of the Earth's spin axis in space. The direction of the Earth's axis in space, shown in orange, changes over time with respect to …

Nutation describes an oscillating or nodding motion in the axis of rotation of a spinning object. It represents a small, periodic oscillation superimposed upon a larger, more stable rotational movement.

NUTATION definition: an act or instance of nodding one's head, especially involuntarily or spasmodically. See examples of nutation used in a sentence.

In the case of the Earth, nutation is the periodic oscillation of the Earth's axis of rotation around its average position on the celestial sphere, due to the external forces of gravitational attraction between …

Nutation was discovered by James Bradley from a series of observations of stars conducted between 1727 and 1747. These observations were originally intended to demonstrate conclusively the …

In this informative video, we will explore the fascinating concept of nutation, a phenomenon that plays a key role in the physics of spinning bodies, particularly in celestial mechanics.

Due to the action of a second force (with associated torque), the angle between the angular momentum vector and the fixed axis (which we’ll call the z-axis) may also change, a process known as nutation.
