Gyroscope (noun)

A device consisting of a spinning wheel or disk that is mounted so as to be free to rotate on one or more axes, used to maintain a stability or to measure orientation and angular velocity.

Origin:

From the french "gyro-", meaning "spinning", and the greek "skopein", meaning "to look at", first recorded in the mid-19th century.

Examples:

1. A gyroscope is an essential component in the navigation systems of ships, aircraft and spacecraft.
2. The gyroscope helps to maintain the balance of the bike even in rough terrain.
3. The sensors used in the drone rely on gyroscopes to determine the orientation and stability of the flight.
4. The balance and orientation of the toy helicopter was controlled by a small gyroscope inside.
5. Gyroscopes are used to measure rotation and acceleration, allowing them to be used in a variety of applications, including navigation, guidance and control systems.
