Complex motion refers to the movement of an object that combines multiple types of motion, such as linear and rotational motion. For example, a spinning top moves in a circular path while also rotating around its axis. This type of motion can be observed in various systems, including machinery and celestial bodies. In physics, complex motion can be analyzed using vector addition, where different motion components are represented as vectors. Understanding complex motion is essential in fields like mechanics and robotics, as it helps in predicting the behavior of moving objects in real-world applications.
