Physical and Non-physical quantities | Definition , differences and examples

Quantities are those which can be measure or can be express in less , more , equal etc . 
There are two types of Quantities  . 

1. Physical quantities

2. Non-physical quantities

Physical quantities 

Physical quantities can be measured in a proper unit and it has a numerical value . Physical quantities are verified scientifically and help us to define laws of physics . 

Examples of physical quantities are mass, amount of substance, length, time, temperature, electric current, light intensity, force, velocity, density, momentum , energy  and many others. A physical quantity is always measured of natural non-living objects ( Inanimate objects ) .

Note – We can differentiate Physical quantities in fundamental quantities , Derived quantities and Supplementary quantities . And by considering other references we can differentiate Physical quantities in Vector , Scalar and Tenser quantities .

Non – Physical quantities

Non- Physical quantities are those quantities that can not be measured by any device ,  does not have unit or  magnitude themselves .  Sometimes these quantities can be compared to each other .

Examples of non physical quantities are represented as Feelings like ; Rudeness, Love , Happiness,  Sadness , Proudness, Respect, Pride, Hate, Angry, Loyalty and Stupidity .

Note – Non-physical quantities does not have numerical values ; units , so we does not use non physical quantities to define the laws of physics .
