Spinning top / gyroscope — precession (3D)

About this app

A fast-spinning top does not topple but precesses: gravity creates a torque τ that turns the angular momentum L sideways (Ω = m·g·r/(I·ω)). Spin and tilt adjustable, the L and τ vectors and the precession circle visible — the basis of the gyrocompass and inertial navigation.
