Write 1 sentence for each defining the meaning of the terms

Write 1 sentence for each defining the meaning of the terms \"forced precession\", \"free precession\" , \"nutation\", \"gyroscopic moment/force\", and \"stability of torque-free motion of a rigid body\"

Solution

Solution :

Forced precession :

The change in the orientation of any body which is subjected to external torque is called forced precession.

Free precession :

The change in the orientation without applying any external moment is called free precession.

Nutation:

It is the rocking motion in the axis of rotation of a large axially symmetric object.

Gyroscopic moment :

Gyroscopic moment is nothing but rate of change of angular momentum which is applied on the gyroscope.

Stability of torque free motion :

It basically tell how the body will be due to the free motion and how stable it will be when free motion is occuring on it.

Please let me know if you need more explanation.
