Which type of motion characterizes an object in uniform circular motion?

An object in uniform circular motion is defined by moving along a circular path at a constant speed. While the speed remains constant, the object's direction is continuously changing, which means its velocity is not constant. This change in direction, while maintaining a consistent speed, results in an acceleration called centripetal acceleration directed toward the center of the circular path. This scenario exemplifies how velocity is a vector quantity, influenced by both magnitude (speed) and direction. Therefore, the key characteristic of uniform circular motion is the combination of constant speed and continually changing direction, making the correct answer the one highlighting this unique aspect of such motion.
