The change in velocity is just the change in velocity. The RATE of change of velocity - how quickly velocity changes - is usually called "acceleration".
It can't. If there is a change in direction, there is a change in velocity ("velocity" includes the direction), and therefore, an acceleration.It can't. If there is a change in direction, there is a change in velocity ("velocity" includes the direction), and therefore, an acceleration.It can't.

If there is a change in direction, there is a change in velocity ("velocity" includes the direction), and therefore, an acceleration.
A change in velocity constitutes a change in direction because velocity includes direction.
"Acceleration" means change of velocity. If velocity is constant, then acceleration is zero.
Change in velocity = Velocity at the end of the period minus velocity at the start of the period.
Yes. Acceleration is a change in velocity; velocity is a change in speed and or direction. I am not sure what motion means in a technical sense (velocity?).
due to acceleration the speed and velocity will change automatically
No. Velocity is the change of location and accelarion is any change that occurs to the velocity of an object.
