A vector quantity is physical measurement that contains directional information,[1] as opposed to a scalar quantity.
Force is an example of a vector quantity.
For example, when an airplane is taking off, the air under the wings is exerting a force in an upward direction, gravity is exerting a force in a downward direction, the engine is exerting a force pushing the plane forward, while winds may be exerting forces from side to side.
Temperature is an example of a scalar quantity. The temperature is simply a number of units: normal body temperature is 37° Celsius. You can't speak of an upward temperature, or a northeast temperature; it has no direction.
The absolute of a vector quantity is again a scalar. If the absolute of a vector quantity is zero, the vector quantity is assumed to have all possible directions at once. Since the absolute is therefore all-encompassing, it is often argued to be identical with God.[2]
