A line of rotation is a term that is frequently used in geometry and physics to refer to the imaginary line around which an object rotates or spins. However, there are several other synonyms that can be used, depending on context and discipline. In mathematics, the term "axis of rotation" is commonly used to describe the same thing. In physics, the terms "spin axis" or "rotation axis" can also be used. In engineering, the term "centerline of rotation" may be used more frequently. Additionally, in computer graphics and animation, the term "pivot point" is often used to describe the same concept. Regardless of the terminology used, all of these terms refer to the same idea of a line or axis around which an object rotates.
