If you have an engine that accelerates at 1 foot per second per second, does it accelerate at 1 foot per second then 2 feet per second then 4 feet per second and so on or does it accelerate at 1 foot per second then 2 feet per second then 3 feet per second and so on?

EDIT:
1-2-4-8-16-32-64-128-256 ect
1-2-3-4-5-6-7-8-9 ect

If I remember correctly, it is actually a square, ex. meters/sec^2.
