As you might already know, distance/time is the first time derivative of displacement, velocity. Accordingly, velocity/time is the second time derivative of displacement, acceleration. Consequently, acceleration/time would be the third time derivative of displacement. This is sometimes called "jerk," but usage of the term is not universal; it may also be referred to as "jolt," "surge," or "lurch." Whatever one calls it, the time rate of change of acceleration may be a useful value to determine in certain advanced and specialized applications, although it would not typically be encountered by high school physics students, or even in bachelors-level collegiate dynamics. As an example, though, jerk must be taken in account when designing roller coasters, because the human body takes time to adjust to changing accelerations.
jerk/time is the fourth time derivative of displacement, and it may be called "snap" or "jounce," but this is an even more esoteric subject. Following from the "snap" name, the fifth and sixth time derivatives of diplacement have been jokingly referred to as "crackle" and "pop."

Acceleration need not always be a constant and uniform.
If it varies with time then the rate of change of acceleration is
acceleration/time.
A force which varies with time will produce such acceleration

In physics, jerk, also called jolt (esp. in British English), surge or lurch, is the RATEOF CHANGE OF ACCLERATION; more precisely, the derivative of acceleration with respect to time, the second derivative of velocity, or the third derivative of displacement.

It would have a meaning if the acceleration is a time function itself, that is acceleration varies with time. In that case... it might mean something...but it depends on the context in which you use it...

the rate of change of the acceleration because x/time means the rate of change of x
x=any physical quantity

The rate acceleration changes in relationship to time is called the jerk. I said jerk,jerk,jerk,jerk.

velocity well its origninally supposed to be a vf-vi/t so in this case it would be vf-vi
