Will angular acceleration remain constant in uniform circular motion?
Okay, that helps to visualize it. Can an object in uniform circular motion have a changing speed?
Yes, an object in uniform circular motion can have a changing speed. Its velocity vector changes direction constantly, which means its acceleration vector also changes direction, causing it to experience a centripetal acceleration. This acceleration towards the center of the circle is what keeps the object moving in a circle. If the magnitude of the velocity vector changes, then the object's speed changes as well.
