Scaler And Vector Quantity

-As we all hear the words scaler quantity and vector quantity but we don't know the real meaning of that and
- we think this is a difficult concept as it seen from the name but actually it's not like that
- These are just two quantity came to exist for differentiate. So let's start what simply it mean

The two types of quantity are
1) Scaler quantity 2) vector quantity

Scaler Quantity :

- A scaler quantity is a one dimensional measurement of a quantity 

- It is a physical quantity that can be described by a single element of number field such as a real number or we can say scaler quantity is a quantity that has only a numerical value and with just this numerical value the sentence is complete and meaningfull too.
- now our next quation is but what is that one dimension so answer is that one dimension can be any like distance (m) ,time (T), mass (M) etc.
Ex. 1)This ball is of 2 kg
      2) Window size is 80 cm

- If we divide one scaler quantity by other scaler quantity we can get scaler quantity  as a result
eg. Distance / Time = Speed

Vector quantity

- A vector quantity has magnitude as well a direction also.

- It simple mean that to describe any quantity as a vector quantity only magnitude or the direction not     make the meaning sentence.
- Vector quantity are velocity, acceleration, linear momentum ,force etc.
ex. 1) Bike has 20 velocity
      2) Man turn right
      3)  Ball has 20 N weight
- From the above sentence we not get the right meaning for that sentence
- So correct sentence are
1) Bike has 20 m/s velocity in right direction
2) Man move 2 meter in the right direction
- Now this become a meaningful sentence
