Spiral motion is a type of circular motion in which an object moves in a curved path around a central point. It is also known as GYRE or gyrational motion. The term 'GYRE' is derived from the Greek word for circle, and it refers to the circular shape of the motion. Gyrational motion is a more specific term that describes the motion of an object in a spiral pattern. Both terms are used to describe the same type of motion.
