Of course. You need to go back and review the definitions of those terms.
Acceleration is the rate at which velocity changes. If velocity is not changing, then
there is no acceleration. But the velocity doesn't have to be zero just because it's
not changing.
Velocity is the speed of an object and the direction in which it's moving. If it's
moving at a constant speed in a straight line, then it has plenty of velocity.
But since the speed isn't changing and the direction isn't changing, there's
no acceleration. If acceleration comes along somehow ... such as by igniting a
rocket motor, or gravity pulling the object downward, or someone reaching out
and giving the object a push, then the speed or direction may change, and
that'll be a change of velocity.
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.
Not necessarily. If the net force acting on a body is zero, the body's velocity will remain constant (assuming no other forces act on it to change its velocity), but it doesn't mean the velocity will be zero. If the initial velocity is zero, then the velocity will remain zero if the net force is zero.
When a falling object reaches its terminal velocity, its acceleration becomes zero. The downward force of gravity is balanced by the upward force of air resistance, resulting in no overall acceleration.
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.
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.

Although the question is stated in a somewhat confusing way, we can state withconfidence that the velocity of the car is NOT uniform, because a value is given forits acceleration. 'Uniform' motion means zero acceleration.
When a falling object reaches its terminal velocity, its acceleration becomes zero. The downward force of gravity is balanced by the upward force of air resistance, resulting in no overall acceleration.
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.
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.
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.
Yes, but it will have a non-zero velocity afterwards.
if it is not moving
Acceleration is the CHANGE in velocity; you're assuming CONSTANT velocity. So the acceleration is zero.
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.
zero because the initial and final velocity is constant . so,difference bet. final velocity and initial velocity is zero
