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

If an object is moving in a circle with a constant speed Its acceleration is constant in what?
It is constant in magnitude. It is changing in direction.
Is motion with constant velocity an example of motion with constant acceleration?
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.
Can you go around a curve with constant velocity?
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.
Why does gravity produce a constant acceleration?
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.
An object will have constant acceleration if?
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.

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.
Where is acceleration greatest in circular motion?
If an object moves in a circle at a constant speed, the magnitude of the acceleration won't change.
Prove that if magnitude of vector A is constant then d by dt of vector A is perpendicular to vector A.?
That is not even true!
Can you go around a curve with constant velocity?
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.
What is the direction of acceleration when moving in a circle?
The direction of the acceleration is towards the center. The magnitude of the acceleration is v2/r.
Is centripetal acceleration a uniform acceleration give reason?
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.
Why does gravity produce a constant acceleration?
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.
Does the speed of a car moving in a circular path at 15 mph remain constant Or does the acceleration or its velocity remains constant?
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

What happens if an object covers equal distances in equal periods of time?
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.
Can an object acceleration if its velocity is constant?
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.
