Web视频字幕. we've learned that axial precession it doesn't change it's not a change in the tilt or the obliquity of our rotational axis it's a change in the direction and over a long period of time 26,000 years it kind of traces out a circle and the main effect of that is that if we wait long enough that our rotational axis or you could say ...
WebApr 4, 2024 · It reacts to the the gravitational influence of the sun and moon like a spinning top whose rotation is distorted by some external force: this causes what has been termed the earth's precession - which means that the earth's axis itself rotates in a circle, leading to a conical movement around the fixed pole of the ecliptic. WebNov 23, 2024 · Precession refers to the way Earth wobbles around on its axis, a bit like a top. This motion is caused by the sun and moon’s gravity tugging on the planet, and is key to understanding how many ancient cultures viewed the sky. So what is precession, exactly?
WebWe illustrate the precession of a gyroscope with an example of a top in the next two figures. If the top is placed on a flat surface near the surface of Earth at an angle to the vertical and is not spinning, it will fall over, due to the force of gravity producing a torque acting on its center of mass. This is shown in Figure 11.20 (a).

WebMay 3, 2024 · by Albert Schödlbauer I saw a picture of precession and nutation of Earth's axis. In German but I suppose it is understandable. The precession is: $$ 360 ^\circ / (25.728 \text{ years}) = 50.2 '' \text{ per year} $$ In the book the autor states that the true rotation axis moves along a small cone wrt the average rotation axis.
