Here is the definition of the work precession as noted from wikipedia:

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.

He explains this phenomenon very clearly and the way it wobbles may puzzle you if you didn’t understand the physics behind it.

We hope you like and video and are inspired to keep learning about physics.
