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?

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

Acceleration is the measurement of the change of velocity (or speed). So if an object is accelerating, it's velocity is changing. If an object has no acceleration, it's velocity is constant. Gravity is a force, which applies acceleration to an object. Other forces include magnetic and nuclear.

Edit: Just to add a little more context, per second per second is the same as per second squared (which is part of the form of the equation used for time when representing acceleration mathematically) e.g. meters per second squared is the same as meters per second per second.

Edit2: To answer your last question, if something is accelerating at 1 foot per second, the amount of feet that is traveled each second will only increase by 1.


If acceleration is constant at 1 foot per second per second then:

Time(seconds) 0 1 2 3 4 5
Speed(feet per second) 0 1 2 3 4 5

If Acceleration was 2 feet per second it would be

Time 0 1 2 3 4 5
Speed 0 2 4 6 8 10
