Direction. Velocity is a vector quantity. Vectors have a scalar size and a vector direction.
Speed is how fast something is going when the direction in which it is travelling is unimportant. Velocity is a measurement of the rate at which an object is changing its position. As such, in order to measure it, one must define both the speed at which an object is moving, and also the direction of movement.
the object's velocity
Velocity gives both speed and direction of an object. While speed is a scalar quantity, velocity is a vector quantity and require direction or bearing in order to be valid.
No. For you to know acceleration you need the rate of change of speed and the direction.

Both.
Velocity describes both the speed and direction an object is moving.
