Yes. There can be an instant during a period of acceleration when speed is zero.

We can think of two examples right away:

1). Drop an object from your hand. As soon as you release it, downward acceleration

begins immediately, but speed is zero.

2). Toss an object (like a Baseball or a stone) straight up. Downward acceleration

due to gravity begins immediately. At first, its effect is to reduce the upward speed.

As soon as the upward speed is all gone, downward speed begins. Acceleration is

constant throughout, but at the instant when upward speed becomes downward

speed, the speed is zero.

Can an accelerating object have zero speed?

No, an accelerating object cannot have zero speed. Acceleration is the rate at which the speed of an object changes over time. If an object is accelerating, its speed is increasing or decreasing, but it cannot be zero.


When is an object not accelerating?

An object is not accelerating when it is moving in a straight line at an unchanging speed (which may be zero).


If the net force on an object is zero then the object is?

Not accelerating. It could be stationary or moving at a constant speed.


Can an object have a zero velocity and still accelerate?

Yes, an object can have zero velocity and still be accelerating if its speed is changing in a direction other than its initial motion. For example, if an object is moving in a circle at a constant speed, its velocity may be zero at a certain point, but it is still accelerating due to the change in its direction.


What three things must an object do to be accelerating?

An object must change its speed, change its direction, or both in order to be accelerating. Any of these changes will result in a non-zero acceleration.


Can particle with velocity or speed at zero be accelerating?

Yes, a particle can have a velocity of zero and still be accelerating if its speed is changing. Acceleration is the rate at which the velocity of an object changes over time, so even if the particle's velocity is momentarily zero, if it is changing, it is experiencing acceleration.


Can An unbalanced force cause an object to change its speed?

Yes, an unbalanced force can cause an object to change its speed by accelerating or decelerating it. When the net force acting on an object is not zero, it will cause a change in the object's velocity, which includes changes in speed.


Meaning of zero acceleration?

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


Can an object can be moving if the net force acting on the object is zero?

Absolutely. The key is to realize that a net force of zero on an object means only that it is not accelerating. This means that an object feeling zero net force can either be stationary or moving at constant speed in a straight line.


Can an object have a speed of 0 while it has an acceleration that is not 0?

Yes. Acceleration is independent of speed. A perfect example of an object with zero speed but nonzero acceleration is an object at the apex of being thrown upward. The entire time it is in the air it is accelerating downward. At its maximum height its speed is zero.


When an object is accelerating What is its speed?

It will have increase in speed with increase in time


What is it when an object is accelerating its speed?

It will have increase in speed with increase in time
