What is defined as the motion of an object in a circular path?

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

Answer: (A)

The motion of an object in a circular path is defined as circular motion. This type of motion involves an object moving around a fixed point or axis, maintaining a constant distance from that point. In circular motion, the object's velocity is constantly changing direction, even if its speed remains constant, due to the centripetal acceleration directed towards the center of the circle. Rotational motion, while related, typically refers to the motion of an object rotating around an axis, where different points in the object may have different velocities depending on their distance from the axis of rotation. Linear motion describes movement along a straight line, not involving any curvature or turning. Periodic motion involves repeated cycles or oscillations, which is not inherently circular unless specified, as it can describe other types of motion such as swinging or bouncing. Thus, circular motion is the most precise definition for an object traveling along a circular path.
