I am not sure what you mean by reversing a zero acceleration. An object's acceleration can, of course, change over time.
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.
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.
Then there will be no acceleration of the object.
Yes, but only at one instant. For instance, if you throw an object straight up, when it reaches the highest point its instantaneous speed is zero, but of course its speed is changing - thus, acceleration is non-zero.
When the net forces acting on an object sum to zero then the object's acceleration is zero.
No, retardation refers to a negative acceleration, which means the object is slowing down. A zero acceleration means the object is moving at a constant velocity.
It is not possible for acceleration to have zero acceleration because the force acting on the object is gravity and g=9.8m/s squared. Gravity is the acceleration It can however have a zero velocity
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.
