The unit for acceleration is m/s/s, or m/s^2. Acceleration is a vector with magnitude and direction. If velocity and acceleration point the same direction, the object is speeding up. If velocity and acceleration point opposite directions, the object is slowing down. Changing direction is also a form of acceleration.

The slope of a position vs. time graph represents the object's velocity: A straight line (constant slope) means the object moved with constant velocity, and a curved line (changing slope) means the object accelerated.
