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.
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.
Yes, a particle can have a velocity of zero and still be accelerating if its speed is changing. Acceleration is the rate at which the velocity of an object changes over time, so even if the particle's velocity is momentarily zero, if it is changing, it is experiencing acceleration.
In uniform circular motion, although the speed of the particle remains constant, the velocity constantly changes direction as it moves around the circle. Since velocity is a vector quantity that includes both speed and direction, despite the constant speed, the changing direction of the velocity means that the particle is not moving at a constant speed.
No, an object moving at a constant speed cannot be accelerating. Acceleration is defined as a change in velocity over time, so if the speed is constant, there is no change in velocity and therefore no acceleration.
No, an object with constant speed is not accelerating. Acceleration is the rate of change of velocity, so if the speed of an object is constant, its velocity is not changing and therefore there is no acceleration.

No. Acceleration is any change of velocity.But its speed can be constant.
No, an object with constant speed is not accelerating. Acceleration is the rate of change of velocity, so if the speed of an object is constant, its velocity is not changing and therefore there is no acceleration.
No, if you are traveling at a constant speed, you are not accelerating. Acceleration refers to a change in speed or direction.
No. An object is accelerating if it is changing speed or direction of travel. Since the person in question is running at a constant speed in a straight line, they are not accelerating.
Since acceleration involves a change in velocity, and object might be accelerating even though its speed is constant.
No, if an object's speed is constant, then it is not accelerating. Acceleration is the rate of change of an object's velocity, which includes both speed and direction. If an object's speed is constant, it means there is no change in velocity and therefore no acceleration.
This is one of those theoretical situations, like the frictionless surface you will see in physics problems. The short answer is that no, a car travelling at a constant speed is not accelerating. Acceleration is a change in velocity over time. Velocity is speed, so if you have zero change in velocity over a period of time, you have acceleration of zero. In the real world, you will have other factors acting on the vehicle, which would affect the acceleration.
When the velocity of a particle is constant, it means there is no change in speed or direction. Therefore, its acceleration is zero because acceleration is the rate of change of velocity. If the velocity is constant, there is no change to be measured, so the acceleration is constant at zero.
