Yes, an object can have a velocity of zero and an acceleration of zero. It's an object with a velocity of zero and no net applied force.

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.


Can an object have zero acceleration and nonzero velocity at the same time?

Yes. An object moving at constant velocity would have zero acceleration.


Is it possible to have an acceleration with constant velocity?

No, the definition of acceleration is the increase change in velocity over time. An acceleration can also be a decrease in velocity over time. Constant velocity refers to an object that maintains the same velocity as time progresses. If the object has an acceleration, its velocity will not remain constant. In the case of rotational velocity there is a constant internal acceleration that has the magnitude v2/r


Is there an acceleration when an object traveling at constant velocity and why?

No. Acceleration is change of velocity / time. If there is no change in velocity, there is no acceleration.




What is the difference between Velocity and Acceleration of an object?

Velocity is the rate of change of distance with time, acceleration is the rate of change of velocity with time.


When the speed of an object is doubled what happens to the acceleration?

Acceleration is the change of velocity per unit time. Once the object has a constant velocity, its acceleration will be zero.


When does a force change the velocity of an object?

If the object is in free-space, and any force applied over a period of time will change the velocity of an object. Force = mass * acceleration. Acceleration = velocity / time. Therefore, Force = mass * velocity/time.


What is the difference between velocity and acceleration?

Velocity of an object is the speed of the object and the direction of its motion. However, acceleration is the change in velocity divided by time it takes for the change to occur.Velocity is describing how an object in a 2+ dimensional plane is changing its position with 1 or 2 dimensional time.ANSWERAcceleration is describing how an object changes its velocity with time.Velocity is defined as Displacement of a body in a particular time.Velocity = Displacement/Time. Whereas Acceleration of a body is defined as change in Velocity of a body at a particular instant of Time.Acceleration = Final Velocity-Initial Velocity/TimeNow If Velocity is Uniform or Constant then Acceleration is ZeroThe same difference as between velocity and position.Velocity is the change of position per time unit.Acceleration is the change of velocity per time unit. If an object, for example, goes faster and faster (or slower and slower), then it is accelerating.The difference is that velocity refers to the speed of something while acceleration refers to the increase of that speed. For example you step on the accelerator to increase the velocity (speed) of your car.Acceleration means, how fast is the velocity changing. Velocity is speed with a direction.Velocity is the distance covered over time; acceleration is the variation in velocity over a period of time.



How is velocity and acceleration the same?

They are not the same. Velocity is the displacement (change in location) over time and acceleration is the change in velocity over time.


Does acceleration occur when an object changes?

Acceleration is change of velocity / time.



Can an object have zero velocity at the same time that it has acceleration?

No, because for an object to accelerate it must increase velocity. Yes, for the infinitesimal moment in which velocity reverses. Check your calculus text.


What is the rate at which the velocity of an object changes over time?

Acceleration is the rate at which the velocity of an object changes over time.


If an object has zero acceleration and does that mean its velocity is zero and Explain?

If an object has zero acceleration, its velocity doesn't have to be zero. Acceleration is a measure of the change in velocity over time. Zero acceleration means there is no change in velocity over time, namely constant velocity. Constant velocity can be any velocity (including zero velocity or "at rest"), so the object's velocity doesn't have to be zero to have zero acceleration.


Can an object have zero acceleration and non zero velocity at the same time?

Of course. Any velocity composed of a constant speed in a straight line indicates zero acceleration.


What is Velocity and Acceleration?

Velocity is the speed of an object in any given direction (constant); acceleration measures the change in speed of an object over time.


Is it possible for an object to have an increasing velocity and an increasing acceleration?

If your acceleration is increasing then by default your velocity has to increase. Acceleration = velocity/time so if acceleration is increasing the velocity is also increasing... And just for fun, just as the change in distance is velocity, and change in velocity is acceleration with respect to time, the change in acceleration with respect to Time is called a jerk



The rate of change of velocity is?

The rate at which velocity changes is known as the acceleration of an object.Calculating acceleration, given velocity can be achieved with the formula:acceleration = change in velocity / change in 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.


Are speed and acceleration the same?

No. Speed is the magnitude of velocity and acceleration is the change of velocity in time.


In what situations are acceleration zero?

Acceleration, which is the change of velocity over the change in time, will equal zero when there is no change in velocity. This can occur when an object is stationary or when an object is traveling at a constant velocity.
