Kepler`s Law of Areal Velocity in Cyclones
... Coriolis force is therefore present in all vortex phenomena whether it is a large scale cyclone in the atmosphere, a tornado, or water swirling out of a kitchen sink. This is real Coriolis force and it can be viewed from any frame of reference. It is a more general example of the Coriolis force that ...

... With the equations (3.6.a.b.c), we found the accelerations of the gyrotational part of gravitomagnetism, that work upon a satellite in a circular orbit about the Earth, whereby the satellite’s orbit plane is under an angle with the Earth’s equator. Obliviously, none of the accelerations is zero, thu ...

... The rotational inertia of the Earth is therefore enormous and a tremendous torque would be needed to slow its rotation down (around 1029 N.m) Question: Would it be more difficult to slow the Earth if it were flat? For a flat disk: I = ½ m.r2 I = 12.3 x 1037 kg.m2 So it would take even more torque to ...

Precession
Precession is a change in the orientation of the rotational axis of a rotating body. In an appropriate reference frame it can be defined as a change in the first Euler angle, whereas the third Euler angle defines the rotation itself. In other words, the axis of rotation of a precessing body itself rotates around another axis. A motion in which the second Euler angle changes is called nutation. In physics, there are two types of precession: torque-free and torque-induced.In astronomy, ""precession"" refers to any of several slow changes in an astronomical body's rotational or orbital parameters, and especially to Earth's precession of the equinoxes.
