A '''vector quantity''' is a measurement that contains both magnitude<ref>Stewart, James. ''Calculus: Early Transcendentals.  Brooks/Cole, 2008</ref> and directional information,<ref>Wile, Dr. Jay L. ''Exploring Creation With Physical Science''. Apologia Educational Ministries, Inc. 1999, 2000</ref>. It is different from a [[scalar quantity]], which contains only magnitude.

Force is an example of a vector quantity, because it includes both a magnitude (push) and a direction (the direction the force is in).  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.
