"Acceleration velocity" is a meaningless phrase.
"Velocity" is the time rate of change of position.
"Acceleration" is the time rate of change of velocity.
Yes, a body can have aceleration without velocity. Consider sin x the position; cos x is the velocity and -sin x is the acceleration. Here the acceleration negative when x=90 degrees and the velocity is zero at 90 degrees.
Objects moving at constant speed in a straight line are said to be in equilibrium. That is there is no force acting on them. If a force was acting there would be aceleration and the velocity would change.
To be moving progressively faster.
Change in speed divided by time.
The definition of acceleration is:Change of velocity, that is, change of speed or direction or both.In popular, every-day usage, 'acceleration' has come to mean 'speeding up', but as youcan see from the definition, that's not accurate.Acceleration can also mean a change in the direction of motion, without any changeof speed.

To be moving progressively faster.
Yes, that's correcf
There are, of course, several formulae that involve acceleration. The basic definition of acceleration is: acceleration = delta velocity / delta time, that is, to get average acceleration, divide the difference of velocity by the time that passed. The same formula also gives you the instant acceleration, if the acceleration is constant. If you want to get instantaneous acceleration, and the acceleration changes, then you need calculus: acceleration = dv / dt (that is, take the derivative of the velocity).
: ......dah, Newton's second law
very bad fuel filter
Basic answer,,,no.
Change in speed divided by time.
A turbo charger
accelleration=force divided by mass force=mass times aceleration
