National 5 Vectors and scalars Adding vectors Scalars have a size, while vectors have both size and direction. When adding vector quantities, it is possible to find the size and direction of the ...

Vectors are kind-of-like ordinary numbers - - which are also known as scalars -- because they have a magnitude, which tells you how big they are. But they have another characteristic, too: direction.

Composition and Resolution of Vectors: Students learn to use trig functions and the Pythagorean Theory to combine vectors and then to resolve vectors into components.

Yes. In introductory physics courses, it is common to just look at vectors with only 2 dimensions (x and y) just to make things simpler. Also, you can have 4 or 5 or even more dimensions in vectors.

I really like the physics textbook Matter and Interactions by Ruth Chabay and Bruce Sherwood. The way that textbook consistently represents vectors is as: I like this notation.
