The concept of rotation around a curve involves a body rotating along a non-linear path, which challenges the idea of rigidity. Unlike rotation around a straight line, this type of motion suggests that the body must adapt to the curvature of the path. The discussion highlights the moon's rotation around the Earth as a practical example of this phenomenon. This type of rotation raises questions about the physical properties of the rotating body. Understanding these dynamics can deepen insights into celestial mechanics and motion.
