A gyroscope is a device that uses the principles of angular momentum to maintain orientation. It consists of a spinning wheel or rotor mounted on a set of gimbals, allowing it to rotate freely in multiple directions. Gyroscopes are commonly used in navigation systems, such as those found in airplanes and ships, to help determine their position and direction. In addition to navigation, gyroscopes are also found in smartphones and gaming controllers, where they help detect motion and orientation. They play a crucial role in stabilizing images in cameras and drones, ensuring smooth and steady footage during movement.
