Acceleration is the rate at which velocity changes. So as Fred said, the velocity is changing at the rate of one foot per second every second. Also known as feet per second squared....or whatever unit of distance you are using divided by the unit of time you are using.
So if a car was accelerating at 8 m/s2 (or 8 meters per second per second), after one second, its velocity would be 8 m/s...after 2 seconds its velocity would be 16m/s...after 3 seconds its velocity would be 24 m/s. The rate at which the velocity is increasing is by 8 m/s every second.
You can also calculate acceleration by the formula: final velocity minus initial velocity divided by time
