Examples of vectors in nature are velocity, momentum, force, electromagnetic fields, and weight. A quantity or phenomenon that exhibits magnitude only, with no specific direction, is called a scalar . Examples of scalars include speed, mass, electrical resistance, and hard-drive storage capacity. Vectors can be depicted graphically in two or three dimensions. Magnitude is shown as the length of a line segment.
Direction is shown by the orientation of the line segment, and by an arrow at one end.
