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)
