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.

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.

Velocity describes how position changes; acceleration describes how velocity changes. Two layers of change! article https://www.khanacademy.org/science/cambridge-o-level-physics-cie/x0e04e0cb682fb793:kinematics/x0e04e0cb682fb793:acceleration/v/acceleration 2021-03-04T17:23:37Z Acceleration Acceleration (a) is the change in velocity (Δv) over the change in time (Δt), represented by the equation a = Δv/Δt. 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.
