## Vectors

In this video, I show you what we mean by a vector quantity and how it can be represented by a directed line segment.

In this video, I show you many of the different ways that vectors can be represented from column vectors in 2 dimensions to using unit base vectors in i, and j.

In this video, I show you the difference between a displacement vector and a position vector.

In this video, I tell you about the properties of equal vectors and opposite (negative) vectors.

In this video, I show you the the meaning behind multiplying a vector by a scalar and run through a couple of examples.

In this video, you are shown the vector triangle for addition and subtraction of vectors in 2 dimensions.

## Worked Examples

I would encourage you to try the following examples as they demonstrate common methods with vectors and act as revision of the topics looked at so far.

### Example 1

### Example 2

In this video, I show you how to find the magnitude (length) of a vector in 2 dimensions.

## Finding a length when given the coordinates of two points
