Concept Of Physics

Introduction to Physics Concept of Physics

Physics is the study of the relationship between matter and energy.  The people who study physics is called physicists

Science

Science is the scientific study of nature.

For Example, how cooling effect occurs

Matter

Matter is anything that has mass and occupies space.

For Example, Solid (chalk), liquid (water) and gas (Oxygen)

Energy

Energy is ability to do work. Energy can be in different forms

For Example, light energy, sound energy, electrical energy, etc.

Relationship between Physics and Other Subject

Physics is the fundamental subject which other subject uses application of physics;

The following is the relation with other subjects

Chemistry

Composition and decomposing of matter involves energy. For Example,   

i)   Cooking stoves, fuel burn to leased heat energy

ii)  Insect killers and Perfumes packed in container by compressed which comes out with high pressure

iii) Fertilizer when they syntheses the heat energy should involved

iv) When tea and other food cooked the heat energy should involved

Biology

Since biology is the scientific subject, which involves living and non-living things, which may be micro and macro organism, it uses application of physics. For Example, 

i)    Microscope which made by physicist is used to observe micro organism

ii)   Syringe is based on pressure

Mathematics

Physicist should master mathematics because physics problems may involve calculation

Astronomy

Astronomy is the scientific study of universe. Universe composed by moon, sun, stars, comets, planets etc. it uses different instruments to study the universe which are made by physicists.

For Example, 

i)    Periscope and telescope are used to observe distant objects like stars etc.

ii)   Material used to build the space like satellite are determined by physicists

Geography

Geography is the study of man and his environment. It includes soil rainfall, mountains etc. it uses application of physics, for Example, 

i)   Many instruments like rain gauge, wind vane developed by physicist

ii)   Barometer which used to measure the atmospheric pressure made by physicist

iii)  Formation of soil and rocks are explained by physics
