Acceleration is the change in velocity with respect to time. Velocity is the change in position with respect to time (not the change in speed with respect to time, as you have written). Both acceleration and velocity are vector quantities, which means they have both a magnitude and a direction.
Speed is simply the magnitude of the velocity. (It's what's called a "scalar" quantity, which is just a number without an associated direction.) An object can have a constant speed, but its direction of motion can be changing over time, so it's velocity is changing. The resulting nonzero change in velocity per unit time is the acceleration.
An object need not be moving in a circle to meet these conditions. An object that moves at constant speed, but follows any path that is not a straight line must experience an acceleration. A circular path (like a satellite's orbit) is simply one example example of this.
Acceleration refers to a change in velocity, which can occur even if the speed remains constant. For example, if an object is moving in a circular path at a constant speed, it is still accelerating because its direction is changing constantly. So, it is possible to be accelerating and traveling at a constant speed at the same time.
No, you are not accelerating if you are traveling in a constant direction with a constant speed. Acceleration is the rate of change of velocity, so if your velocity remains constant, there is no acceleration.
Acceleration refers to any change in an object's velocity, which includes changes in speed or direction. It is possible to have a constant speed while still accelerating if the direction of motion changes, for example, when moving in a circle at a constant speed. So, while the speed remains the same, the change in direction constitutes acceleration.
No. 'Acceleration' means a change in speed or direction over time. If the car is moving at a constant speed in a constant direction, then it isn't accelerating.
Since acceleration involves a change in velocity, and object might be accelerating even though its speed is constant.

0. "Constant speed" means it is not accelerating.

its not, if ur accelerating ur not staying at a constant speed.
Acceleration is a change in velocity, which includes changes in speed or direction. When an object is traveling at a constant speed, it can still be accelerating if it is changing direction, like in circular motion. In this case, the object's velocity is changing even though its speed remains constant.
That's correct.
Velocity is speed in a certain direction. You can keep speed the same, and if you change direction then you have changed velocity.
true
Not possible, acceleration dV/dt =0.
