Gyroscope

Definition

A gyroscope is a device that utilizes the principles of angular momentum to maintain orientation and provide stability. By spinning rapidly around its axis, a gyroscope can resist changes to its orientation, making it essential for navigation and stabilization in various applications, especially in inertial measurement units. Gyroscopes are commonly used in vehicles, aircraft, and spacecraft to help determine their orientation and assist with navigation systems.
