VELOCITY
That is called "velocity".
This is not true. Acceleration includes direction, but speed does not. Speed in a particular direction is called velocity.
Acceleration is the change in an ogjects speed or a change in an objects direction of motion or both of these. If instead of speed you use the word velocity , which is both an object's speed and its direction of motion, then you could say "acceleration is the change in an objects velocity" and that would cover all the possibilities in one statement.
It involves the change in velocity, which is a vector quantity, meaning that it is also the change in speed.
translatory motion
when you know both speed and direction of an objects motion you know the velocity of an object.

I'm pretty sure its the acceleration. If its not that, its the Velocity.

Yes! In most problems direction needs to be defined as either positive or negative.

This is one definition of acceleration (including deceleration) - any change in the speed of motion of a moving object, or in the direction of its motion. Motion is a vector value with both speed and direction.
