What is the definition of Physics? How it differs from Chemistry and Biology?

Hi Anshuman,

Physics is the branch of science concerns with the nature  and properties of matter, energy , sound , mechanics,  radiation , structure of atoms , magnetism etc.

Chemistry is also a branch of scuence that deals with the study of chemicals and elements of atoms , protons and neurons etc.  

Biology is also another branch of science dealing with the study living organisms and living beings. Further it's classified into categories one is botany - study of plants and the other is zoology - the study of animals,  reptiles.

Physics is the main branch of science " the study of nature by its physical activitys like motion momentum energy( electron ....and rays )is called physics. chemistry and biology are also studied about nature but only their chemical and biological change ,not all. Main one is that they studied the part which is left by physics. As you know the part thermal physics contain most of physical  chemistry.

 Chemistry and physics are two fields that have a lot in common with one another. They're both physical sciences, and both study the structure and properties of matter. In this sense they are both rather abstract and focus on the very tiny though physics also focuses on the very large quantities.

The goal of physics is to understand the entire universe in a fundamental way. Physicists collect data about the world and use it to derive basic, mathematical laws that explain how everything in the universe functions. The holy grail of physics would be to discover a theory of everything that unifies all the mathematical laws physicists have discovered
