Suppose we have to go 10km from Point A to Point B.

This 10km is the distance travelled.

It is only value - 10, nothing else.

This is a **scalar quantity.**

Now, suppose we say,

We go 10 km East from Point A to Point B.

So, we have travelled 10 km East

It has value - 10, and direction - East.

So, this is a **vector quantity**.

In this chapter, we will talk about vectors. The topics include

- Basics - Difference between
**scalars and vectors**, with example **Graphical Displacement**- Where we represent Displacement like 40 km, 30° East of North, in the Graph.- We also discuss what is a position vector, and
**different types of vectors** - Then we learn what happens when a
**scalar is multiplied to a vector** - We learn what are
**Equal**Vectors and**Unit Vectors**, and do some questions on them - Finding
**Direction Ratios**and Direction**Cosines** - Then,
**adding two vectors** - Finding
**vector joining two points** **Section formula**in vectors- Checking if 3 points make a
**right angled triangle** - Checking
**if 2 vectors are collinear** - Checking
**if 3 points**(or vectors) are collinear - Then,
**Scalar Product**of Vectors and its properties - Finding
**projection**using scalar product **Vector product**of vectors, and its properties- Finding
**area**using vector product (Area of parallelogram = Vector Product)
