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.

Of course, since the instantaneous velocity indicates the velocity at a certain moment in time it does not describe the change in this velocity a moment from the stated instance, which is the acceleration. Therefore, the initial velocity can be zero and still experience an acceleration since the velocity may change in the next instance.

The instantaneous velocity of an object is merely the derivative of the position function, the acceleration which is the 2nd derivative of position. Therefore acceleration is first derivative of velocity, thus, the slope of the velocity function may be non zero while the function value at the given time may be zero. For instance consider a simple parabola, y = t2, as the position function, this is obvious from the non linear nature of the graph that there is an acceleration experienced. The velocity function is, by taking the derivative, v = 2t, which is a linear function, stating a constantly changing velocity. The acceleration, differential once again, is a = 2. Thus, we have found that the acceleration at every point in time the acceleration is 2. Looking at the velocity function, it is obvious that there is a zero at t = 0, while at all time the acceleration is 2. Thus, this is an example showing that a function value in a function does not describe its immediate changes from this current point to the next, thus knowing the instantaneous velocity of an object does not give any information about its acceleration unless a change in this velocity is given.

No. An object at rest (zero velocity), will remain at rest (have zero acceleration), unless acted upon by an unbalanced force. This is part of Newton's first law of motion. So an object cannot have a speed of zero with an acceleration greater or less than zero.

Zero acceleration is when a particle doesn't move in an amount of time, thus the velocity is a constant.

Yes, it can. The speed for such object is a constant for both direction and absolute value of speed.

Yes, it is.

Consider a ball thrown into the air. At the highest point of the arch its velocity is zero, yet it's constantly accelerated by Earth's gravitation.

Drop an object from a height h. In the beginning, its velocity is zero, but it is accelerating towards the center of the earth with acceleration g.

Yes, you can move at any speed, as long as it remains the same, acceletarion occurs when there is change of velocity (change of speed or course)

When forces are balanced compare the acceleration of an object at rest and an object in motion?

An object at rest has zero acceleration. If the set of forces acting on a moving object is balanced, then the moving object also has zero acceleration.


If a body is moving with constant velocity is it moving with constant acceleration?

An object moves with constant velocity when there is no net force acting upon it. If there are no forces acting on an object, or if the forces acting on it "cancel out" leaving a net force of zero acting on the object, it will have zero acceleration. With a zero acceleration, the velocity of the object will be constant.


Can an object have zero velocity and nonzero acceleration?

Yes. An object moving at constant velocity has zero acceleration. The constant velocity van be any constant including zero velocity. Mathematics acceleration a=dv/dt = 0. Solving this gives v = constant.


Can a body have acceleration without velocity?

Yes. Velocity is speed per unit of time with a direction vector telling you which way the object in question is moving. Acceleration is a change in velocity - in any part of velocity. If something like, say, a rock is in deep space (a zillion light years from anything) and it's moving along unaffected by any gravity or other forces, it has some velocity (some speed in a given direction, or is moving at some distance per unit of time in a given direction), but it isn't changing speed or direction. If something is moving without changing its speed or its direction (either of which requires a force to act on the object - to accelerate the object), it has zero acceleration. Such an object is said to have a constant velocity and will have zero acceleration. Certainly if an object is not moving, it has zero velocity and zero acceleration, but that's probably not what is being asked. It has velocity (zero) and no acceleration. To recap, an object can have a non-zero velocity and zero acceleration.


Why is an object in equilibrium during constant motion?

When an object is in equilibrium, the acceleration is zero. When the acceleration is zero, the velocity does not change; the non changing velocity includes the case when the velocity has value zero.

An example of zero acceleration would be what?

If you are moving at a speed of ceratin speed and there is no force trying to slow you down, and there is no force trying to speed you up. Then there is zero acceleration. An example would be : an object in out in space, if you throw a object away from you the object will float away, since there is no force working on the object after you throw it the object is moving away in a locked speed from you, but have zero acceleration because there is no force affecting the object


What is the word that means zero velocity?

Any object which is at rest has zero velocity, for example a rock on the road. car parked at lane, a motor which is not moving or stop. a man sleeping. home office statue of liberty. anything that is at rest has zero velocity.

What must you know about an object Moving in a straight line to calculate its acceleration?

You must know its mass and the net force. If it is moving at constant velocity, the net force is zero and the acceleration is zero.

Can it be possible that a particle have constant speed must have zero acceleration?

It's possible, but not necessary, that a particle moving with constant speedhas zero acceleration. In order for acceleration to be zero, it's also necessarythat the particle be moving in a straight line.An object moving with constant speed around a curve has acceleration."Acceleration" does not mean "speeding up".


Zero acceleration will the velocity be constant?

Whenever velocity is constant, the acceleration is zero. This also works when the velocity is zero, the acceleration is zero. That pretty much means the object isn't moving. But, yes/ If velocity is constant, accleration is zero.


Can an object be moving if 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.


Can an object have zero velocity and nonzero acceleration?

Yes. An object moving at constant velocity has zero acceleration. The constant velocity van be any constant including zero velocity. Mathematics acceleration a=dv/dt = 0. Solving this gives v = constant.
