Answer 2

Answer:

d) Speed

Because Uniform Circular Motion (UCM) occurs when an object moves with a constant speed around a circular path. The speedremains constant, but the velocity does not because the object's direction is always changing. The object must accelerate towards the center of the circle to stay in the circular path.
