The definition of acceleration is:
Change of velocity, that is, change of speed or direction or both.
In popular, every-day usage, 'acceleration' has come to mean 'speeding up', but as you
can see from the definition, that's not accurate.
Acceleration can also mean a change in the direction of motion, without any change
of speed.

Traveling in any direction, but moving is acceleration. if a particle moves in a circle and comes to the initial position, then the velocity would be zero. acceleration is a scalar quantity and not a vector quantity. answered by K.Sreram from India
The force toward the centre of the circle is called the centripetal force. centrpetal acceleration.
Circular -Brittany Goraczkowski
Yes, IF it maintains constant speed on the track. The academic definition of velocity is speed and the associated direction, a vector. A car traveling in a circle is constantly changing direction. However, most people, including physicists when they are not writing textbooks, treat velocity and speed as interchangable such that a car going a constant speed on a circular track would be considered to have a constant velocity even though the direction in which it is traveling is constantly changing.

If speed does not change then the object is moving with constant speed. when object moves in a circle its speed does not remains constant. Speed of object remains constant only if it moves along linear path.
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.
The angular momentum is a constant.
Yes its diameter is its width which is constant where ever it's measured inside the circle
A circle has an unlimited number of lines of symmetry. These lines are called the diameter. Why does a circle have an unlimited number of lines of symmetry? It's because a circle has a constant diameter regardless of where the diameter is measured from.
