For example, an object thrown upwards, when it is at its highest point. This situation is only possible for an instant - if the acceleration is non-zero, the velocity changes, and can therefore not remain at zero.
No, if an object has zero acceleration, its velocity cannot be changing. If the velocity is nonzero, it must either be increasing or decreasing, which requires acceleration.
Yes. If it weren't so, an object that isn't moving could never be made to move at all! Of course, once you apply acceleration (which implies a change of velocity), the object's velocity won't stay zero. But for a brief instant, the velocity can be zero while accelerating.
Yes, an object moving at a constant velocity has zero acceleration even though it has a non-zero velocity. For example, a car driving at a steady speed on a straight highway has a constant velocity but zero 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.
When acceleration is zero, the object's velocity can still be changing if the initial velocity is not zero. However, if acceleration is zero and the initial velocity is also zero, then the object's velocity will remain constant.
No, if an object has zero acceleration, its velocity cannot be changing. If the velocity is nonzero, it must either be increasing or decreasing, which requires acceleration.
Yes, an object can have zero velocity and nonzero acceleration. This occurs when the object is changing its direction but not its speed. For example, in circular motion, the object's velocity is constantly changing direction, leading to a nonzero acceleration even when its speed is constant.

"Acceleration" means change of velocity. If velocity is constant, then acceleration is zero.
A change in velocity can be effected only by acceleration. Therefore, if the acceleration is zero, there is no change, so final velocity equals initial velocity.
Acceleration is the CHANGE in velocity; you're assuming CONSTANT velocity. So the acceleration is zero.
If your velocity is constant, then your acceleration is zero.
Velocity at zero means the object is not moving, while acceleration at zero means the object is moving at a constant velocity. Velocity at zero can be motionless or stationary, while acceleration at zero indicates that there is no change in velocity, even if the object is moving.
In a theoretical scenario with constant velocity, the true acceleration would typically be zero.
