What is the definition of rotational motion?

• A. Motion of an object in a straight line
• B. Motion of an object rotating around an axis
• C. Motion of an object falling freely
• D. Motion of an object at constant speed

Answer: (B)

Rotational motion refers to the movement of an object as it rotates around a fixed point or axis. In this context, an object can be any rigid body, such as a wheel, planet, or any other object that undergoes a circular path about a specific axis. Key characteristics of rotational motion include parameters like angular displacement, angular velocity, and angular acceleration, which describe the rotation in terms of angles instead of linear distance. This type of motion is fundamental in understanding various physical phenomena, such as the behavior of gears, wheels, and celestial bodies, where the relationships between forces and motion differ significantly from linear motion.
