Velocity is speed together with its direction.
Acceleration indicates a change in velocity ... speed or direction or both.
Change of direction means acceleration, even if speed is constant.
Constant velocity means constant speed and direction ... zero acceleration.
If you are traveling at a constant speed with changing direction there is a change in velocity, so you are accelerating.
Yes.
Since acceleration involves a change in velocity, and object might be accelerating even though its speed is constant.
Velocity is speed in a certain direction. You can keep speed the same, and if you change direction then you have changed velocity.
Are you talking about the Illinois Particle accelerator? Well I think that it doesn't go at a constant speed but at a constant Acceleration, since it is accelerating and not staying at one speed is is therefor Constant Acceleration until they slowly work it up to almost the speed of light.

No. Acceleration is any change of velocity.But its speed can be constant.
An object with a constant (vector)velocity is not accelerating. An object with a constand (scalar)speed can actually be accelerating, a car with a constant speed that passes around a corner is changing direction and is subjected to a lateral acceleration.
Unless the object is changing its direction, it is not accelerating. Constant velocity implies that speed and direction are constant, and for acceleration to occur, either speed, direction, or both values must be changing.
Velocity is speed in a certain direction. You can keep speed the same, and if you change direction then you have changed velocity.
Acceleration is the time rate of change of velocity. Velocity is a vector. It has a magnitude ( speed ) and a directio. If either the speed or the direction of motion changes the object is accelerating. Example; an object moving in a circle at constant speed is accelerating because its direction is continually changing.

It stops accelerating, and falls the rest of the way at constant speed.
You can be accelerating and traveling at a constant speed if you change directions.
The speed is called "terminal velocity".
