It changes over time.
An object is accelerating if its velocity is changing.
No. The definition of acceleration is the change in an object's velocity over time. Acceleration must then be zero since velocity remains constant.
When an object stops accelerating, it either maintains a constant velocity or comes to a complete stop depending on the forces acting upon it. If the net force acting on the object is zero, it will move at a constant velocity. If there is a net force opposing its motion, the object will eventually come to a stop.
When an object reaches terminal velocity, the force of gravity pulling it downward is equal to the force of air resistance pushing up against it. At this point, the object stops accelerating and falls at a constant speed.
When velocity changes, the speed and/or direction of an object's motion is altered. This can result in acceleration or deceleration, depending on the direction of the change in velocity. If the velocity increases, the object is accelerating; if the velocity decreases, the object is decelerating.

Accelerating...or was accelerating.

No. The definition of 'acceleratiion' is 'any change in velocity'.
When an object reaches terminal velocity, the force of gravity pulling it downward is equal to the force of air resistance pushing up against it. At this point, the object stops accelerating and falls at a constant speed.
When velocity changes, the speed and/or direction of an object's motion is altered. This can result in acceleration or deceleration, depending on the direction of the change in velocity. If the velocity increases, the object is accelerating; if the velocity decreases, the object is decelerating.
When a falling object stops accelerating but is falling at a constant velocity, it is called terminal velocity.
The speed may, or may not, change. Acceleration means that the velocity changes; this means that either the speed changes, or the direction.
Acceleration is the rate of change of velocity with respect to time. If an object's velocity is increasing, it is accelerating positively. If its velocity is decreasing, it is accelerating negatively.
A moving object being accelerated will show a change in its velocity (it may move faster, or slower, or experience a change in direction). A stationary object will respond to acceleration only if there is no other force acting to prevent its response. For example: gravity is a constant force of acceleration, but objects cannot move toward the center of the earth if they are being blocked by another object.
When an object is not accelerating at all. It has constant velocity.
