This allows you to measure how fast velocity changes in meters per second squared (m/s^2). Acceleration is also a vector quantity, so it includes both magnitude and direction.

If an object's speed and/or direction is changing, it is accelerating. If an object is speeding up, its velocity and acceleration are in the same direction. If an object is slowing down, its velocity and acceleration are in opposite directions. If neither an object's speed or direction are changing, it's moving at constant velocity and its acceleration is zero.
