If the motion of a body is that imparted by a single force, its path will be rectilinear, and may be represented by a straight line. The elements of a force are: (a) its point of application; (b) its direction; (c) its magnitude. The force may be represented by a line beginning at the point of application, and extending in the direction in which the force acts, to a distance which is a measure of its magnitude. This means that all lines representing magnitudes must be drawn to the same scale. The direction of the motion of a body or of the action of a force is indicated by placing on the line the point of an arrow. Such lines are called vector lines, or vectors.
