If a particle moves in a circle describing equal angles to equal times, its velocity vector
Correct answer: C. Changes in direction
- A. Remains constant
- B. Changes in magnitude
- C. Changes in direction
- D. Changes both in magnitude and direction
Explanation
If a particle moves in a circle describing equal angles to equal times, its velocity vector changes in direction because the velocity vector is always tangent to the circle at the point where the particle is located. As the particle moves around the circle, the direction of the tangent changes, so the direction of the velocity vector also changes. The magnitude of the velocity vector may or may not change, depending on the specific motion of the particle. If the particle is moving with a constant speed, the magnitude will remain constant. Options A, B, and D are incorrect because they do not fully capture the relationship between circular motion and the velocity vector direction.

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.
