Yes. (if the initial velocity is zero) if not then velocity = initial velocity + acceleration x time

A change in velocity can be effected only by acceleration. Therefore, if the acceleration is zero, there is no change, so final velocity equals initial velocity.

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

If you have constant acceleration, then you can't have constant velocity. (Unless the acceleration is constantly zero.)Final velocity = [initial velocity] + [ (acceleration) x (time) ]

No. Acceleration is the change of velocity. If velocity is constant, at any speed, acceleration is zero.

With no acceleration the final velocity is the same as the initial velocity. If the initial velocity is zero, the object is not moving. Unless there is some kind of force influencing the object. Then you have to calculate the acceleration: a=F/m where "F" is the force influencing the object (in Newtons) and "m" is its mass (in kilograms).

If an object has zero acceleration, its velocity doesn't have to be zero. Acceleration is a measure of the change in velocity over time. Zero acceleration means there is no change in velocity over time, namely constant velocity. Constant velocity can be any velocity (including zero velocity or "at rest"), so the object's velocity doesn't have to be zero to have zero acceleration.

Going back to definitions, Velocity is change of distance with time; and acceleration is change in velocity with time. Initially, the velocity is zero, as is the acceleration, BUT the Force of Gravity attracts the falling mass, and causes velocity to appear. But the continued application of the Force of Gravity causes the velocity to increase. And as we know, increase in velocity is acceleration. [space for QED]

Acceleration refers to the change of velocity per time unit. If the velocity doesn't change, acceleration is zero.

If you know the initial and final velocity you can determine the acceleration (Velocity final- Velocity initial)/time = acceleration This can also be seen by integrating the acceleration. In this case lets assume acceleration is constant, then: acceleration=C Integration from time=initial to time=final gives C*(time final-time initial)=velocity final-velocity initial This integration scheme can also work if acceleration is not constant. In this case you must know how acceleration or velocity changes with time.

no, you need to know its initial velocity to determine this; if initial velocity is zero then distance is 1/2 acceleration x time squared

'v' generally refers to final velocity 'u' generally refers to initial velocity (because not everything starts from a motionless state, where 'u' would equal zero) It is better to annotate initial velocity as v0 (v-sub-zero or simply v-zero).

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.

Only for an instant. Acceleration is a change in velocity. When the derivative of acceleration with respect to time is zero, the velocity would be zero.

Acceleration is equal to final velocity minus initial velocity over time. So, it will affect the outcome of the equation depending on what the initial velocity is.

Acceleration is the CHANGE in velocity; you're assuming CONSTANT velocity. So the acceleration is zero.

Acceleration is changing velocity. Zero velocity means no motion. Zero acceleration means constant, unchanging motion.

Velocity final - velocity initial / acceleration X time

the formula for finding acceleration is final velocity, minus initial velocity, all over time. So if you have the acceleration and initial speed, which is equal to the initial velocity, you must also have time in order to find the final velocity. Once you have the time, you multiply it by the acceleration. That product gives you the difference of the final velocity and initial velocity, so then you just add the initial velocity to the product to find the final velocity.

yes the acceleration is at zero because there is no change in acceleration if the velocity is constant

At terminal velocity (constant velocity), the acceleration is zero, but prior to that, there is a downward acceleration.

Acceleration is an object's change in velocity divided by its change in time. So: acceleration=(final velocity - initial velocity)/(final time - initial time)

The amount of time it would take an object to travel a distance with constant acceleration depends on its initial velocity, according to the equation: d = vit + 0.5at2 Where d is displacement, vi is initial velocity, t is time, and a is acceleration. Note: if the object starts from rest, its initial velocity, logically, is zero.
