What is the acceleration of a constant velocity?

By definition, acceleration means change in velocity. So if the velocity is constant, this means both speed and direction are constant. And there has to be at least one of these things changing for the velocity to change, the acceleration is zero if none of these things change and the velocity is said to be constant.

Correspondingly, what is the acceleration is constant mean?

The Meaning of Constant Acceleration. Sometimes an accelerating object will change its velocity by the same amount each second. As mentioned in the previous paragraph, the data table above show an object changing its velocity by 10 m/s in each consecutive second.

Can an object be accelerating if it is moving with constant speed?

An object can accelerate while traveling at constant speed but not at constant velocity. This is because acceleration is a measure of the change in velocity over time. Speed is a scalar quantity with magnitude but not direction while velocity is a vector quantity with both magnitude and direction.
