If acceleration varies with time, it can of course AT ONE PARTICULAR INSTANT be equal to zero. However, it can't both change over time and remain at zero all the time.

Can an object have zero acceleration and eventually-reverses its acceleration?

I am not sure what you mean by reversing a zero acceleration. An object's acceleration can, of course, change over time.


What will be instantaneous acceleration if average acceleration is zero?

If the average acceleration is zero, it means that the object's velocity is not changing over time. Since instantaneous acceleration is the acceleration at a specific moment in time, it can still have a non-zero value depending on the instantaneous velocity of the object at that moment.


When the acceleration of an object is zero what is the velocity at the same time?

As long as acceleration is zero, the object's velocity is constant.


What is the net acceleration in a non uniform motion?

The net acceleration in a non-uniform motion is the overall change in velocity over time, taking into account both the magnitude and direction of acceleration. It is typically calculated as the rate of change of velocity with respect to time, and can vary throughout the motion depending on external forces acting on the object.


Can stationary have non zero angular acceleration?

No, an object is considered stationary when it has zero velocity and zero acceleration. Angular acceleration refers to the rate at which an object's angular velocity changes over time. If something has a non-zero angular acceleration, it means that it is rotating at a changing rate.


Meaning of zero acceleration?

Zero acceleration means no change in velocity and no force on the zero accelerating body.


Can a stationary object have a non zero angular acceleration?

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.


What is net acceleration in a non uniform motion?

For uniform motion, the acceleration is zero. For non-uniform motion, the acceleration is something different than zero - at least, most of the time.


What happens to the velocity if acceleration is zero?

The velocity stays the same, it is constant


Does a dish resting on a table have constant acceleration?

No, a dish resting on a table does not have constant acceleration. In fact, it has zero acceleration because it is not moving. Constant acceleration only occurs when an object's velocity changes at a constant rate over time.


What is called negative accelarration?

Deceleration. Negative acceleration = Velocity is decreasing by time. Positive acceleration = Velocity is increasing by time. Zero acceleration = Velocity is the same by time.


When an object and acceleration is zero at some instant t in time its velocity is?

If an object's acceleration is zero at a specific instant in time, its velocity can either be zero or a constant non-zero value at that instant. This means that the object could be either at rest or moving with a constant velocity at that particular moment.
