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.

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.

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.

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 ...
