Question

When acceleration is constant, can the direction of velocity of a body change if yes, how

Answer 1

Constant or not, if the acceleration is in a different direction from the velocity then yes, direction and therefore velocity will change. Both acceleration and velocity are vectors and if you change the direction of a vector velocity, even if the magnitude (speed) is the same it is still a change in velocity.

Answer 2

Hi friend here is your answer.

Yes.

In circular motion velocity changes as direction of object changes but magnitude can or cant.

But acceleration is always towards the centre and its constant.
