	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.
