"Rotational" refers to the movement of an object around a central point or axis. This type of motion is commonly seen in various systems, such as the spinning of a top or the orbiting of planets around a star. In physics, rotational motion is characterized by parameters like angular velocity and torque. In everyday life, rotational motion is evident in many machines and devices. For example, the wheels of a bicycle rotate around their axles, allowing the bike to move forward. Understanding rotational dynamics is essential in fields like engineering and robotics, where precise movement is crucial for functionality.
