... degrees/sec or revolutions/sec or radians/sec Example Problem: Earth makes one rotation (3600) about its axis in one day (24 hours) If 3600 = 2 π rad and 24 hours = 86400 sec And 2 x π = 6.28 Then, 2 π rad / 86400 sec = Earth’s angular speed = 7.27 x 10 -5 rad/sec ...

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.
