rotationsakse
A rotationsakse, or axis of rotation, is a fundamental concept in geometry and physics describing the line around which an object or a set of points turns. Imagine a spinning top; the line that the top revolves around is its axis of rotation. In three-dimensional space, a rotationsakse is a specific line that remains stationary during a rotation. All points on the object move in circles, and the centers of these circles all lie on the rotationsakse.
The concept of an axis of rotation is crucial for understanding various phenomena. For example, the Earth
The direction of rotation is typically described as either clockwise or counterclockwise relative to the perspective
