# Gyroscope

###### What is it ?
gyroscope is a device that uses the effect of conservation of angularity to maintain a stable axis of rotation with respect to an external frame of reference. It was invented in 1817 by Jean-Bernard-Léon Foucault, a French physicist. The history of the gyroscope goes back to the beginnings of classical physics, where it was used to demonstrate the rotation of the Earth. In 1852, Foucault used a large spinning pendulum to prove that the Earth rotated, which revolutionized our understanding of our planet. The first practical applications of the gyroscope were for rotating compasses, used for sea and air navigation. Gyroscopes have also been used to maintain stability in vehicles, such as wheeled vehicles and aircraft, as well as attitude control systems for satellites and space vehicles. The formula that describes the behavior of a gyroscope is the precession equation, which describes how the angle of precession varies with moment of inertia, angular velocity, and tracking force applied to the axis of rotation: Ωp = (L x Ω) / I Where Ωp is the angular velocity of precession L is the angular momentum of the object Ω is the angular velocity of initial rotation I is the moment of inertia of the object An example A common use for a gyroscope is in platform stabilization systems, such as stabilization systems for cameras or drones.
