Only instantaneously. If an object is being negatively accelerated, it will be slowing down. If the negative acceleration continues to act on the body, it may, at some point have zero velocity because it has come to a stop, but still have the force acting on it. In the next instant, the object will then be accelerated in another direction. This isn't a "trick" answer. It is just offered to explain a situation in mechanics where an object with some initial velocity is experiencing negative acceleration due to some decelerating force. The dynamics are pretty simple and easy to get your head around if you think about them.
What else can I help you with?
When a body has constnat velocity what is the acceleration?
When a body has constant velocity, the acceleration is zero. This is because acceleration is the rate at which velocity changes, so if velocity is constant, there is no change and hence no acceleration.
If a body is moving with a uniform velocity.what will be its acceleration?
If a body is moving with a uniform velocity, its acceleration will be zero. Acceleration is the rate of change of velocity, so if the velocity is constant, there is no change in velocity over time and thus zero acceleration.
What is the acceleratipn of a body with uniform velocity and why?
The acceleration of a body with uniform velocity is zero because acceleration is the rate of change of velocity. If the velocity is constant, then there is no change in velocity over time, so the acceleration is zero.
Can a body have acceleration with zero velocity?
Yes, but only for an instant. For example, if you throw a stone up, when it is at its highest point it has a velocity of zero, but its acceleration is -9.8 m/s2. If there is acceleration, the velocity can not remain at zero.
Can a body have an acceleration when it is momentarily at rest?
No, a body cannot have acceleration when it is momentarily at rest. Acceleration is the rate of change of velocity over time, so if the body is at rest, its velocity is zero, and therefore its acceleration is zero as well.
When a body has constnat velocity what is the acceleration?
When a body has constant velocity, the acceleration is zero. This is because acceleration is the rate at which velocity changes, so if velocity is constant, there is no change and hence no acceleration.
Why is the body moving with a uniform velocity is zero?
The body is not zero, but the sum of all forces on it is. -- "Uniform velocity" means no acceleration. -- Acceleration is force/mass . -- If acceleration is zero, that's an indication that force must be zero.
Why is acceleration zero when the body is moving with a constant velocity?
Acceleration is the CHANGE in velocity; you're assuming CONSTANT velocity. So the acceleration is zero.
If a body is moving with a uniform velocity.what will be its acceleration?
If a body is moving with a uniform velocity, its acceleration will be zero. Acceleration is the rate of change of velocity, so if the velocity is constant, there is no change in velocity over time and thus zero acceleration.

An a body more with constant acceleration but with zero velocityif yeswhy?
No. Well, such a body can have zero velocity for a brief instant, but it won't stay at such a velocity, because "acceleration" implies that the velocity changes.
If a body starts from rest what can be said about the acceleration of body?
If a body starts from rest, it means its initial velocity is zero. In this case, if the body is in motion, it has undergone acceleration to reach that velocity. Therefore, the acceleration of the body must be non-zero, indicating a change in velocity over time.
The velocity of a body was noted to be constant during five minutes of its motion What was its acceleration during this interval?
The acceleration of the body was zero during this interval because its velocity was constant. Acceleration is the rate of change of velocity, so if the velocity does not change, the acceleration is zero.
Is it possible for a body with zero velocity to have non-zero acceleration?
Yes, but only for a single instant in time. When you throw a golf ball or a rock straight up, it has the constant downward acceleration of gravity from the moment it leaves your hand, but its velocity is certainly not constant. The velocity steadily decreases until the peak of the toss, and then it switches from upward to downward velocity. At the very peak, the velocity is zero for an instant.
Can a body be in motion but 0 acceleration?
Yes, a body can be in motion but have zero acceleration if it is moving at a constant speed in a straight line. Acceleration measures the rate of change of velocity, so if velocity is constant, acceleration is zero even though the body is in motion.
