What type of motion involves a body moving along a circular path?

• A. Linear motion
• B. Rotational motion
• C. Circular motion
• D. Translational motion

Answer: (C)

The motion described by the term "circular motion" specifically refers to the movement of an object along a circular path. In this type of motion, an object continuously changes direction as it travels along the circumference of a circle. This involves a constant radius from the center of the circle, and the forces acting on the object—like centripetal force—are directed towards that center, enabling the curved path. Understanding circular motion requires recognizing that it can involve uniform circular motion, where an object moves at a constant speed around the circle, or non-uniform circular motion, where the object's speed varies. Key parameters such as angular velocity, angular acceleration, and centripetal acceleration are crucial in describing this motion. In contrast, linear motion represents a straight-line path, rotational motion involves an object rotating around an axis without necessarily following a circular path, and translational motion covers overall movement from one location to another without regard to the path's curvature.
