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 ...

If one arrow is twice as long as another, it represents a force which has twice the magnitude. The diagrams show three examples of vectors, drawn to different scales.

The Test of Understanding of Vectors (TUV) is one of the most used tests to investigate students’ comprehension of vectors. However, to our knowledge, the test has not been tested for students in ...

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.

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.

Physics and Python stuff. Most of the videos here are either adapted from class lectures or solving physics problems. I really like to use numerical calculations without all the fancy programming ...

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.
