Koffer mit einem Gyroskop

Lift the suitcase and try to move it to all sides and notice its unexpected reactions. There is a fast spinning gyroscope ??“ a flywheel turning in bearings with insignificant friction ??“ situated inside the suitcase. The spinning gyroscope has a tendency to preserve the direction of the axis of its rotation and prevents the efforts of external forces to tilt this axis. The gyroscope is a device used in navigation, particularly in aircraft and ballistic missiles. It is also important for navigation in space.
