To say that an object is being accelerated, means that
1) it is at rest,
2) it is moving,
3) it is either at a state of rest or a state of constant velocity,
4) its state of motion is changing,
and we define acceleration to be
5) a change in speed.
6) a change in velocity.
7) the rate at which speed changes.
8) the rate at which velocity changes.
