Vectors - basics (theory)

1. Distinguish between a vector quantity and a scalar quantity.
A vector quantitiy has a magnitude(size) and a direction.
A scalar quantity only has a magnitude(size).
2. Define: (a) Parallel vectors (b) Equal vectors (c) Inverse vectors
(a) Parallel vectors must have same direction (not necessarily same magnitude).
(b) Equal vectors have the same magnitude and direction.
(c) Inverse vectors have same magnitude but exact opposite direction.
