A gyroscope is a device that helps measure or maintain orientation and angular velocity. It consists of a spinning wheel or rotor mounted on a frame, which allows it to rotate freely in multiple directions. When the rotor spins, it tends to resist changes to its axis of rotation, making it useful for navigation in various applications, such as in airplanes and spacecraft. Gyroscopes are also found in everyday devices like smartphones and drones. In a smartphone, they help with features like screen rotation and motion sensing. Similarly, in drones, gyroscopes stabilize flight, ensuring smooth and controlled movements.
