Article 8 - Vectors
The expression AB, in geometry, is merely the name of a line. Here it indicates the operation by which the line is drawn, that of carrying a tracing point in a certain direction for a certain distance. As indicting an operation, AB is called a Vector, and the operation is completely defined by the direction and distance of the transference. The starting point, which is called the Origin of the vector, may be anywhere. To define a finite straight line we must state its origin as well as its direction and length. All vectors, however, are regarded as equl which are parallel (and drawn towards the same parts) and of the same magnitude. Any quantity, such, for instance, as a veloecity or a force, which has a definite direction and a definite magnitude may be treated as a vector, and may be indicated in a diagram by a straight line whose direction is parallel to the vector, and whose length represents, according to a determinate scale, the magnitude of the vector.
