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.

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.


Is the net force acting on a body is zero will the velocity be 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 body have 2ms accleration in 15 seconds with a velocity 30ms does the velocity of the car uniform?

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 has reached its teminal velocity its accleration?

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.


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.


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.


Can a body have without velocity?

Yes, but it will have a non-zero velocity afterwards.


Could the body's velocity be zero?

if it is not moving


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.


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.


What is acceleration of a body moving with uniform velocity?

zero because the initial and final velocity is constant . so,difference bet. final velocity and initial velocity is zero
