Acceleration is the rate of change of velocity. This can change with time. For example the rate of acceleration of a car will change if you put your foot on the gas (or the brake). The initial acceleration of an object is just its acceleration at time t=0.
P.S. The initial acceleration for a dropped ball on earth is 9.8 ms^-2. It is the initial velocity which is 0.

the initial acceleration is when everything begins. Example: you drop a ball. The initial acceleration is 0, because it is not moving downward in your hand before you drop it. The acceleration of the ball is found when it is already in motion by the equation
a=change in V/change in t
a is acceleration,
V is velocity
t is time
Hope this helps!

If the rate of acceleration defers initially, finally and some times in the middle then it is called initial acceleration and final acceleration. There is no deference between them they are only acceleration.

Acceleration is the rate of change of speed with time. Sometimes the rate of the change of speed with time changes too. Therefore something may have an initial acceleration, and then it may have a lower or higher acceleration subsequently.

Initial acceleration is just the acceleration that you start with, not necessarily remaining constant.
