Centripetal force is a force that makes a body follow a curved path: it is always directed orthogonal to the velocity of the body, toward the instantaneous center of curvature of the path. - See more at: http://www.chacha.com/question/what-is-the-path-of-a-moving-body-whose-acceleration-is-constant-in-magnitude-at-all-times-and-is-perpendicular-to-the-velocity#sthash.pqrkWxfT.dpuf
Such a particle is moving in a circular path.
It is constant in magnitude. It is changing in direction.
Well, technically yes, and we even know the magnitude of the constant acceleration.If velocity is constant, that tells you that acceleration is zero, which sounds likea constant to us.
Yes, it is. Trajectory also depends of direction of acceleration, not only it's magnitude. When you consider circular orbit, the agnitude of centripetal acceleration is constant, but the vector directions changes every moment to point constantly at the center.
If one consider the mass and the radius of the Earth constant, then the gravity produces a constant acceleration. This is Newton's Theory about Universal Gravition.
well, something has to be pushed by a constantly growing force. Constant acceleration would occur for example if you drop something in a vacuum. Dropping something in normal circumstances is a nearly constant acceleration too.

If an object moves in a circle at a constant speed, the magnitude of the acceleration won't change.
That is not even true!
Yes, it is. Trajectory also depends of direction of acceleration, not only it's magnitude. When you consider circular orbit, the agnitude of centripetal acceleration is constant, but the vector directions changes every moment to point constantly at the center.
The direction of the acceleration is towards the center. The magnitude of the acceleration is v2/r.
No it is not because its direction is constantly changing. It is not a constant force. Force has direction as well as magintude and while it magnitude is constant its direction is not.

The magnitude of the velocity will be constant however the direction will be constantly changing. The acceleration will remain constant towards the centre of the circle

Then you can say that the object's speed and the magnitude of its velocity are constant, and the magnitude of its acceleration is zero.
No. It is a matter of definition. Acceleration is defined as a change of velocity. Technically, one must distinguish between velocity and speed. Velocity is a vector and includes the information about the magnitude (speed)and direction. One can have a constant speed and an acceleration (as in circular motion) but, by definition, constant velocity means zero acceleration.
