When a body moves along a circular path, its velocity
Correct answer: C. Changes continuously
- A. Remains constant
- B. Becomes zero
- C. Changes continuously
- D. Always increases
Explanation
When a body moves along a circular path, its direction is constantly changing, even if the magnitude of the velocity remains constant. Therefore, the velocity vector is continuously changing, making the velocity itself change continuously.

About Angular and Linear Quantities
Rotational motion relates angular displacement, angular velocity and angular acceleration to linear displacement, tangential velocity and tangential acceleration through the radius. Questions use radians, v equals r omega and tangential acceleration, while distinguishing tangential velocity from centripetal acceleration and angular quantities from their linear counterparts.
