If an object undergoes a uniform circular motion, then its

In uniform circular motion, an object travels along a circular path at a constant speed. However, velocity is a vector quantity defined by both magnitude and direction. Even though the magnitude (speed) remains constant, the direction of the instantaneous velocity vector changes continuously as the object moves around the circle. Because acceleration is defined as the rate of change of velocity, this constant change in direction implies that the object is always accelerating. This specific acceleration is called centripetal acceleration, which points toward the center of the circle. While the magnitude of this acceleration may be constant, its direction also changes as the object rotates, meaning the acceleration vector itself is not uniform. Therefore, the most accurate statement is that the velocity changes due to the continuous change in the direction of motion.
