Acceleration, in physics, is the rate of change of velocity of an object with respect to time. An object's acceleration is the net result of any and all forces acting on the object, as described by Newton's Second Law.

If i gave you a number for acceleration, what does that tell you?
I'm accelerating at 13 m/s^2. Which direction am i traveling in the first place? Will my acceleration totally oppose my motion, help increase, the motion, or neither?
You need some information on the direction of the acceleration to understand where in space the motion is changing. However, In a 1 dimensional example you do not need acceleration to be a vector. You can only go in 2 directions, + and -. so if you are used to doin 1-d problems, like you do the first week of the physics course, you do not need vector valued functions to analyze motion.
If you understand that velocity is a vector and the properties of vectors, you can see that you are dividing the velocity vector by a change in time, a scalar. A vector multiplied by a constant, or divided same thing, results in a vector by the properties of vectors.
