According to the "Physics Classroom" website (refer to the link, below), an object changing its speed, whether increasing or decreasing, is said to be "accelerating".
That means that either its speed, or its direction, or both, are changing.
When you (or an object) travel without changing speed, then you have constant velocity (speed). This means there is no change in speed (acceleration) when you (or an object) is traveling.
Yes. 'Acceleration' means either speed or direction is changing. If direction is changing,then there is acceleration, even if speed is constant.
Acceleration is zero when the object's speed and direction stop changing.
The rate at which the speed or direction of its motion is changing.

It is speed or velocity.

Changing, varying or accelerating
The rate at which the speed or direction of its motion is changing.
The rate at which the speed or direction of its motion is changing.
Changing speed.
Yes, it is.
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.
Acceleration is simply a measurement of how the speed is changing, over time.
