No.
It is a matter of definition. Acceleration is defined as a change of velocity.
Technically, one must distinguish between velocity and speed. Velocity is a vector and includes the information about the magnitude (speed)and direction. One can have a constant speed and an acceleration (as in circular motion) but, by definition, constant velocity means zero acceleration.
No
No. An object traveling at a constant velocity is not accelerating.
No. Acceleration is change of velocity / time. If there is no change in velocity, there is no acceleration.
If a velocity or speed is constant there isn't an acceleration. This is because the acceleration is the change in speed or velocity and if it's constant then there sn't a change.
No. The definition of acceleration is the change in an object's velocity over time. Acceleration must then be zero since velocity remains constant.
As long as acceleration is zero, the object's velocity is constant.
Yes. An object moving at constant velocity has zero acceleration. The constant velocity van be any constant including zero velocity. Mathematics acceleration a=dv/dt = 0. Solving this gives v = constant.
Changing at a constant rate equal to acceleration.
rate of acceleration
The velocity increases at a constant rate.
"Acceleration" means change of velocity. If velocity is constant, then acceleration is zero.
Such and object is said to be in equilibrium. No acceleration and no force.
No, since acceleration is defined as a change in velocity. If there is no change, there is no acceleration.
