Which statement best describes the velocity of an object undergoing uniform circular motion?
The magnitude of velocity remains constant, but its direction continuously changes around the circle.
In uniform circular motion, an object moves along a circular path at a constant speed, meaning the magnitude of its velocity never changes.
However, velocity is a vector quantity that depends on both magnitude and direction, and in circular motion the direction of motion keeps changing at every point along the circle.
Because the direction changes continuously, the velocity is not constant even though its magnitude stays the same, and this changing velocity produces centripetal acceleration directed toward the centre.
Hence, the magnitude of velocity remains constant, but its direction continuously changes around the circle.
