dude324's answer: according to
v=u+at if a=0 this implies v=u , thus
yes it can. Even if acceleration is zero, it could have a constant velocity and could be moving.
Lydia's answer: No, because an object at rest remains at rest unless acted upon by an unbalanced force.
velocity may be zero or may not be zero i.e. if the object may continue to move with uniform velocity.
When the net force on an object is zero and it doesn't move, the object is in a state of equilibrium. This means that the forces acting on the object are balanced, resulting in no acceleration.
No. If the sum of all the forces on the object is not zero, then the object's acceleration is not zero, meaning that either its speed or direction of motion, or both, are changing.
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.
An object can still be moving with zero acceleration if it is moving at a constant velocity. When acceleration is zero, the object's velocity remains constant, meaning it continues to move at the same speed and in the same direction without any change in speed or direction.

I am not sure what you mean by reversing a zero acceleration. An object's acceleration can, of course, change over time.
As long as acceleration is zero, the object's velocity is constant.
The acceleration would also be zero in this case.

No, a stationary object cannot have a non zero angular acceleration. Angular acceleration is a measure of how an object's angular velocity changes over time, so if an object is not rotating, its angular acceleration is zero.
Yes. Acceleration is defined as a change of speed and/or direction of motion. If the speed and direction of motion are constant, then there is no acceleration.
Acceleration being zero is equivalent to the statement that an object's velocity doesn't change.
