acceleration can mean... (check all that apply)
an object is speeding up
an object is slowing down
an object is changing direction

Explanation:

Acceleration is the rate of change of velocity. Velocity is a vector quantity (has both magnitude and direction). So, a change in velocity can occur due to a change in speed (speeding up - increase in magnitude of velocity, slowing down - decrease in magnitude of velocity) or a change in direction (even if speed is constant, since velocity direction changes, there is an acceleration as in circular motion where centripetal acceleration changes the direction of velocity).

Answer:

an object is speeding up, an object is slowing down, an object is changing direction.
