FAQs on GYROSCOPE: Spin and Precession axis, Active gyroscopic and Reactive gyroscopic couple Video Lecture - Basic Physics for IIT JAM

1. What is the spin axis of a gyroscope?
The spin axis of a gyroscope is the axis around which the gyroscope spins. It is also referred to as the axis of rotation.
2. What is the precession axis of a gyroscope?
The precession axis of a gyroscope is the axis around which the gyroscope precesses. Precession is the wobbling or rotating motion that a gyroscope undergoes when a torque is applied to it.
3. What is an active gyroscopic couple?
An active gyroscopic couple refers to the torque produced by the gyroscope due to its spinning motion. When the spin axis of a gyroscope is not aligned with the direction of an external force, it produces a torque perpendicular to both the spin axis and the force, resulting in an active gyroscopic couple.
4. What is a reactive gyroscopic couple?
A reactive gyroscopic couple refers to the torque produced by the gyroscope in response to an external torque acting on it. When a torque is applied to the gyroscope, it undergoes precession, and this precessional motion generates a reactive gyroscopic couple that opposes the applied torque.
5. How does a gyroscope maintain its stability?
A gyroscope maintains its stability through the principle of gyroscopic stability. When a gyroscope is spinning, it opposes any force or torque applied to it that tries to change its orientation. This stability is due to the conservation of angular momentum, which causes the gyroscope to resist any external influence and maintain its original orientation.
