M-R5   :   Gyroscopes and tops

	UNIT:	Rotation of rigid body
	PURPOSE:	Illustrate conservation of angular momentum; Demonstrate precession, nutation.
	EQUIPMENT:	1. Large gyroscope with electric motor 2. Large free gyroscope (Pasco) 3. Assorted other free gyroscopes 4. Stand-up gyroscope (Russian) 5. Assorted tops (to be acquired)
	SUGGESTIONS:	1. Gyroscope "remembers" a direction 2. Precession changes direction when:  (a) the gravitational torque is applied at a different point (b) direction of spinning reversed  3. Precession rate inversely proportional to spinning rate
	DISCUSSION:	See captions for the links provided above.
