The mouse wheel has a certain amount of lines that are scrolled with each scroll. This is often called "scroll speed"
An acceleration would increase/decrease the scroll speed dynamically based on how often the wheel scrolls in a certain amount of time. So if I rotate the wheel fast also the speed is increased meaning one also needs to rotate the wheel as often as one would need to if scrolling slower. I think this is the usecase - accuracy or speed in scrolling can be delivered as needed.
I am not sure, whether there is also something like scroll speed implemented. At least KDE offers a setting for it.
So if speed is implemented one can implement "acceleration" as something that changes the speed. Also I'd suggest a changeable value how strong the acceleration will be.
To explain my understanding of acceleration:
