What is uniform circular motion?

When an object moves in a circular path with a constant speed

In uniform circular motion, what is the difference between a scalar and vector quantity?

Scalar quantities are described with only magnitude, while vector quantities need both magnitude and direction

Why does velocity change in uniform circular motion even if the speed is constant?

Due to changes in the object's direction
