dumb question, but what effect does acceleration have per second?

If a ball rolling at an acceleration of 2 m/s/s, and goees like that for 10 seconds, will it be 0m/s at second 0, 2 at 1, 4 at 2, and so on?

That's what (linear) acceleration means: an increase in speed over time.
 
Acceleration is the change in velocity per unit time. So if you have an acceleration of 2 m/s/s, your velocity after 10 seconds will be ##v_0 +20 m/s##. So if initial velocity is zero, then yes, just as you described.
 
Ah ok. So it literally works how it sound?

Lovely.

Thanks. I didn't even finish browsing and you answered!
