Not at all. Zero acceleration just means that the velocity is not changing ...
the motion is in a straight line at a consgtant speed.

Why is it that their is an acceleration when a car is moving?
There is only acceleration if the car's velocity changes. If it moves at a constant velocity, then there is no acceleration.
Can velocity be 0 but speed not 0?
Speed and Velocity are two words that mean the same. You may mean, "Can Velocity be 0 but acceleration not 0". Yes, this occurs when a moving object is changing direction (say from moving forwards to moving backwards) or is just about to move or, at that very instant has just come to a halt. In all these cases, speed /velocity is zero but the body is accelerating. Don't forget, the word acceleration is also used when an object is decelerating (slowing down).
What is the Acceleration of a car that got up to 45 ms from a rest position in 3 seconds?
Velocity at time 0 sec = 0m per sec Velocity at time 3 sec = 45m per sec Acceleration is 45/3 = 15m per sec if the acceleration is uniform
What is the acceleration of an object that starts stopped and after 5 seconds is going 25mm per hour?
the acceleration is increasing speed Acceleration = velocity change / time velocity change = 0 to 25 mm/hr = 25 mm/hr time = 5 seconds therefore acceleration = 25/5 mm/hr per second = 5 mm per hour per second.
If A car travels down the highway at 55 mph its speed is what and its acceleration is what?
Acceleration is zero since 55 mph is velocity and it is constant. Acceleration is defined as the rate of change in velocity. The speed is the absolute value of velocity so it is also 55.
If an object is moving at a constant velocity what do you know about its acceleration?
"Acceleration" means change of velocity. If velocity is constant, then acceleration is zero.
Is it possible for a body to have acceleration when moving constant speed and constant velocity?
No; acceleration means the velocity changes.No; acceleration means the velocity changes.No; acceleration means the velocity changes.No; acceleration means the velocity changes.
How an object could still be moving with the 0 acceleration?
Zero acceleration means that the velocity doesn't change. It doesn't mean that there is no velocity.
When acceleration is 0 why does velocity have to be at a maximum?
It doesn't. If acceleration is zero, that just means that velocity isn'tchanging ... the motion is in a straight line at a constant speed.
Is it possible for a body to have an acceleration when moving with constant velocity?
No, if an object is moving with constant velocity, it is not experiencing any acceleration. Acceleration refers to a change in velocity over time, so if the velocity is constant, there is no acceleration.
What is the Difference between Uniform motion and uniform acceleration?
"Uniform motion" means constant velocity ... constant speed in a straight line. "Acceleration" means any change in velocity ... speed or direction. So 'uniform motion' means zero acceleration.
The velocity of a body was noted to be constant during five minutes of its motion What was its acceleration during this interval?
Acceleration means speeding up or slowing down, a change in velocity. Since the velocity was constant, the acceleration was. 0
When velocity is zero and acceleration is less than zero does the speed increase?
if acceleration is <0 and velocity =0 then you got the handbrake on
Are velocity and acceleration related?
Yes, velocity and acceleration are related. Acceleration is the rate of change of velocity with respect to time. This means that acceleration describes how the velocity of an object is changing.
The rate at which velocity changes?
The rate at which velocity changes is called acceleration. It describes how quickly an object's velocity is changing with respect to time. Positive acceleration means the object is speeding up, negative acceleration means it is slowing down, and zero acceleration means the velocity is constant.
What are acceleration and velocity?
'Velocity' means the rate at which position changes, and the direction in which it changes. 'Acceleration' means the rate at which velocity changes, and the direction in which it changes.
Can uniform angular velocity has acceleration?
No, uniform angular velocity means no angular acceleration.
