No. A object can have acceleration while moving at a constant speed (like the earth in its orbit around the sun). But once you use the word "velocity", you've expanded the decription of its motion to include the direction as well as the speed. The definition of acceleration is a change in either speed or direction, so if there is acceleration, then either the speed or the direction of the velocity (or both) is changing, so the velocity is not constant.

No; acceleration means the velocity changes.No; acceleration means the velocity changes.No; acceleration means the velocity changes.No; acceleration means the velocity changes.
"Acceleration" means change of velocity. If velocity is constant, then acceleration is zero.
Constant velocity means that an object is moving at a consistent speed and in a straight line, without any changes in direction. Acceleration is the rate at which velocity changes with time, so if there is no change in velocity, there is no acceleration. So, an object moving at a constant velocity does not have any acceleration.
The acceleration of a vehicle moving with uniform velocity is zero. This is because acceleration is the rate of change of velocity, and if the velocity is constant and not changing, then the acceleration is zero.

Acceleration is the CHANGE in velocity; you're assuming CONSTANT velocity. So the acceleration is zero.
"Acceleration" means change of velocity. If velocity is constant, then acceleration is zero.
An object moves with constant velocity when there is no net force acting upon it. If there are no forces acting on an object, or if the forces acting on it "cancel out" leaving a net force of zero acting on the object, it will have zero acceleration. With a zero acceleration, the velocity of the object will be constant.

A motion with a constant speed will always be moving the same speed A motion with a constant acceleration will constantly be gaining speed, and does not remain moving at the same speed.
The acceleration would be zero because the turtle is moving at a constant speed
Constant velocity means that an object is moving at a consistent speed and in a straight line, without any changes in direction. Acceleration is the rate at which velocity changes with time, so if there is no change in velocity, there is no acceleration. So, an object moving at a constant velocity does not have any acceleration.
There is only acceleration if the car's velocity changes. If it moves at a constant velocity, then there is no acceleration.
The acceleration of a vehicle moving with uniform velocity is zero. This is because acceleration is the rate of change of velocity, and if the velocity is constant and not changing, then the acceleration is zero.
Velocity is parallel to acceleration when an object is moving with constant speed in a straight line, as the direction of the velocity and acceleration vectors are aligned. This means that the object's speed may be constant, but its direction can change.
