Wanted and unwanted outer forces will always change the velocity of an object.
The velocity of object always changes with wanted or unwanted outer forces.
Then the object accelerates; its velocity changes.Then the object accelerates; its velocity changes.Then the object accelerates; its velocity changes.Then the object accelerates; its velocity changes.
This is not always the case. But if an object moves in a circle, at constant speed, its velocity will change. Velocity is a vector - consisting of the magnitude (the speed), and a direction. So by definition, if the direction changes, the velocity changes - you have a different vector.
Yes, acceleration is the how the velocity changes. This also includes when an object turns
No. As used in physics, the word "acceleration" means that THE VELOCITY CHANGES. More precisely, it refers to how quickly the velocity changes, in symbols, dv/dt.

Force changes the velocity of an object by acceleration, a=F/m.

A single force on an object, or a net force ... the sum of all forces on it when the sumis not zero ... always changes the object's velocity ... speed, or direction, or both.

velocity
An object accelerates if its velocity changes. More precisely, "acceleration" is the rate of change of velocity (how quickly velocity changes), or in symbols, dv/dt.
"Acceleration" implies that the velocity changes.
No, velocity is the instantaneous speed of an object, the rate of change would be the acceleration of the object.
If an object's velocity changes over time, it is accelerating.
