It is constant in magnitude. It is changing in direction.
The force toward the centre of the circle is called the centripetal force. centrpetal acceleration.
In toward the center of the circle.
In order to change the direction of the velocity, acceleration is absolutely required. And as long as you've got it, there's no reason why it can't be constant. An object moving in a circle at a constant speed ... like a TV satellite ... has constant acceleration, and the direction of its velocity is constantly changing.
acceleration
An object moving at constant speed in a circle. Acceleration is rate of change of velocity, as velocity is speed in a certain direction, when moving in a circle an object's velocity is constantly changing, as its velocity is changing it is accelerating.
centripetal acceleration
The force toward the centre of the circle is called the centripetal force. centrpetal acceleration.
When the direction changes. A simple case is an object moving in a circle, at constant speed.
In toward the center of the circle.
If the speed of the object doesn't change, then yes.
This type of acceleration occurs when an object is moving around a circle at a constant speed. As the object moves around the circle, the direction of its velocity is constantly changing. This type of acceleration is called centripetal acceleration. The direction of the acceleration is toward the center of the circle. I hope this answers your question. A car traveling 25 MPH turns 30-degrees to the left without losing speed -- it has accelerated.

An object moves with constant velocity when there is no net force acting upon it. If there are no forces acting on an object, or if the forces acting on it "cancel out" leaving a net force of zero acting on the object, it will have zero acceleration. With a zero acceleration, the velocity of the object will be constant.
acceleration
A motion with a constant speed will always be moving the same speed A motion with a constant acceleration will constantly be gaining speed, and does not remain moving at the same speed.
An object can move in a circle at different speeds.
Yes, it it's going round in a circle, for example.
