In this lesson, we will learn how to calculate the precession angular velocity of a gyroscope given its mass, radius, and rate of revolution.

Q1:

The precession angular velocity of a gyroscope is 2.5 rad/s. The mass of the rotating disk is 0.82 kg and it has a radius of 50.0 cm. The distance from the center of mass to the pivot is also 50.0 cm. What is the rotation rate of the disk?

Q2:

A spinning top has a moment of inertia 2 . 3 × 1 0 − 4 kg⋅m^{2} and a radius of 5.00 cm from the center of mass to the pivot point. The top spins at 33 rev/s and it is precessing. Through how many revolutions does the top precess in 12 s?

Q3:

A gyroscopically spinning top has a precession frequency of 5.0 rad/s on Earth. If the spinning top was used on the Moon, what would its precessional frequency be?
