INTRODUCTION

 Physics is a branch of science whose objective is the study of components of matter and their mutual interactions. This cannot be possible without   defining  the quantity to be measured and the units for measuring it. Such a  standard unit should be internationally accepted and easily reproducible  

The  International System of Units (SI unit) is all about what is being discussed here. SI units contain seven fundamental units and two supplementary  fundamental units  as shown in table 1 and 2 below

Fundamental Units 

Those physical quantities which are independent to each other are called fundamental  quantities and their units are called fundamental units.

Derived Units

Those physical quantities which are derived from fundamental quantities are called derived  quantities and their units are called derived units. e.g., velocity, acceleration, force, work etc.

Scalar and Vector Quantities:

Scalar  Quantities:

Scalar quantities are those quantities that have only magnitudes. They do not have directions.Examples of scalar quantities:

(I) speed

(ii) distance

( iii) time

( iv) volume

(v) area

(vi) temperature

Vector Quantities:

Vector quantities are those quantities that have both magnitudes and directions.Examples of vector quantities:

  1. Displacement
  2. Weigh
  3. Force
  4. Acceleration due to gravity
  5. Electric field
  6. Magnetic field

     Differences Between Scalar and Vector Quantities:

 Scalar quantities

 Vector quantities

It has only magnitude.

 It has magnitude and direction

 it direction can not be determined.  

 It direction can be determined

It is not represented by line and arrow.

 it is represented by line and arrow

Similarities Between Scalar And Vector Quantities:

  1. They are physical quantities in physics
  2. They both have magnitudes
  3. Their magnitudes can be determined by calculations
