Kantachse

Kantachse refers to a theoretical or actual line of rotation for an object, particularly in the context of physics and engineering. It is often used when discussing angular momentum or moments of inertia. When an object rotates, it does so around an axis. This axis can be an external one, or it can be an axis that passes through the object itself. The term "Kantachse" emphasizes that this axis is a defining characteristic of the rotation. For a rigid body, the principal axes of inertia are special axes of rotation. If an object rotates about one of its principal axes, it will continue to rotate about that axis without any external torque being applied. Understanding the Kantachse is crucial for analyzing the dynamic behavior of rotating systems, such as spinning tops, flywheels, or planetary bodies. In some contexts, it may also be used in less technical discussions to simply describe the line around which something is turning.
