Velocity is a three dimensional vector quantity composed of speed and direction components.
Prior to the development of vector arithmetic, the only arithmetic available for such calculations was quaternion arithmetic. Quaternions are a special type of complex number, except that they have one real and three imaginary parts.

Do Both speed and acceleration include the direction of an object's motion?
No. The velocity of an object is how fast it is moving as well as the direction of the motion. So when considering one dimension, the velocity can be positive or negative. The speed of the object is simply the magnitude (absolute value, in the case of one dimension) of the velocity, with no direction. Acceleration is the change in velocity and does include direction. So if an object has a positive velocity (in one dimension) and its speed increases, the acceleration is negative. However, if the speed of an object moving the negative direction increases, then the acceleration is negative, because the velocity becomes "more negative."
What happens when you have unbalanced forces acting on an object?
Then the object accelerates; its velocity changes.Then the object accelerates; its velocity changes.Then the object accelerates; its velocity changes.Then the object accelerates; its velocity changes.
What is the velocity of a object?
the velocity of an object is its speed and direction
What is the difference between an object's speed and a object's velocity?
The difference between an object's speed and an object's velocity is that the object's speed is how fast it is going, and the object's velocity is how many units of speed the object has traveled.
What is an object that always changes the velocity of the object?
Wanted and unwanted outer forces will always change the velocity of an object.
What does The velocity of an object include besides speed?
It also includes the direction.

The distance an object travels in one unit of time is?
"speed" or "velocity" (if you include a direction)
What is the velocity of a object?
the velocity of an object is its speed and direction
How can you tell an object has moved?
Because of its velocity (velocity is the rate of change of position), an object will move. An object is stationary if it has no velocity because it will not be able to move without velocity. Therefore, you can tell that an object has moved because of velocity.
What is the difference between an object's speed and a object's velocity?
The difference between an object's speed and an object's velocity is that the object's speed is how fast it is going, and the object's velocity is how many units of speed the object has traveled.
