A gyroscope (from Ancient Greek γῦρος gŷros 'round' and σκοπέω skopéō 'to look') is a device used for measuring or maintaining orientation and angular velocity. [1][2] It is a spinning wheel or disc in which the axis of rotation (spin axis) is free to assume any orientation by itself.
A gyroscope is a mechanical or electronic device that utilizes the principle of angular momentum to maintain its orientation relative to the Earth's axis or resist changes in its orientation.
gyroscope, device containing a rapidly spinning wheel or circulating beam of light that is used to detect the deviation of an object from its desired orientation.
According to the English Oxford Dictionary, a gyroscope is a “device consisting of a wheel or disc mounted to spin rapidly about an axis free to alter direction. The orientation of the axis is...
In its most basic form, a gyroscope is a wheel or disc, mounted on a gimbal so it can spin rapidly around an axis that is free to change direction. The angular momentum of the spinning rotor causes it to maintain its attitude even when the assembly on which it’s mounted is tilted.
