# Basic Units and Measurement concept

Hello Friends,
Good Morning every body so far we have studies Physical World you should study step by step every concept is related with each other for better understanding go through each post.
Today our topic is important and interesting second chapter Physics.
Units and Measurement:

Very first we have to discussed about physical quantity here we study about nature in physics and nature is around us whatever object we see and interact with this we see in nature different object have different characteristics.Each and every component of nature having different characteristics like chock, board, light,earth, air, water many more each and every component we sense around nature.

This natural component has to nomenclature on the basis of their characteristics and we want to measure that characteristics because in some component it is large value and in some component small value of that characteristics, take some example if we put a chock in our hand and feel force on your hand very small but second time put a 5kg mass then feel force on your hand it will be large so what we observe here both of this object having a single characteristics small chock is pushing my hand very little but heavy mass 5kg pushing my hand large so pushing is a single characteristics in both object with different values. similarly for small size object and large size object it will be characteristics of same with different values so characteristics of nature which can be measured is called “physical quantity”.
