We’ve been studying physics since our childhood. In lower classes, if talk about CBSE board it is taught combinedly with chemistry and biology altogether in a science book. From class 9th all three main branches of science are taught differently, which means there separate books for each of them. The means of all this is to make you realize that we have been studying Physics since class 2 or class 3 but we still don’t know What is physics and its branches? Simply, physics is the branch of science that deals with the physical world and matter. Basically, Physics is all about understanding the motion of matter, energy, and forces of the universe.

Source: SafaltaGoing for the typical definition of Physics then Physics deals with understanding the structure of matter and its interaction with fundamental constituents of the observable universe. Also, physics is natural science as it studies nature and natural phenomena. Recommended: Study for your Exams with Safalta School online.

Branches of Physics:
If we search on Google for branches of physics there are 51 branches Google will show. But it's not possible to cover all branches. In this article, the most important and main branches of physics are discussed below:
Branches are areas for defining the scope of physics, and the areas and fields of studies that involve physics are its branches.
So, the main branches of physics are:

Let’s understand these branches in detail:
Classical Physics is one of the most popular branches among other branches. It basically deals with energy and matter. Classical Physics includes the Laws of Motion and Gravitation given by Sir Issac Newton. To be specific physics till 1900 and before comes under classical physics and new developments and theories after 1900 were Modern Physics.
As mentioned physics after 1900 is Modern Physics. Modern Physics is all about the theory of relativity and quantum mechanics. Albert Einstein and Max Planks were the discoverers of this branch. Unlike, classical physics modern physics doesn’t consider energy and matter as different entities. Here, they are two sides of one coin.
Nuclear Physics is concerned with the study of atomic nuclei which consist of protons and neutrons.
Nuclear physics has its own advantages as well as disadvantages.
Positive applications of this branch can be seen in magnetic resonance, power generation, medicines, etc… Nuclear weapons are the negative aspect of this branch.

One of the important branches of physics, Astrophysics is a sub-field within Astronomy. It studies how the law of physics and chemistry explains the origin of the universe and celestial bodies in the universe. Cosmology and Planetary Sciences are closely related to Astrophysics and often called sister sciences.
Atomic Physics involves the composition and constituents of atoms other than the nucleus. Mainly, it is concerned with understanding the electrons in the shells and around the nucleus.
Another significant branch of physics studies the propagation, movement, and behavior of light. It includes the phenomena such as Reflection & Refraction. Optics also studies the nature of different wavelengths and intensities. Physical optics and Geometric optics are sub-fields within optics.
Acoustics is the study of sound. It involves the transmission and behavior of mechanical waves in different mediums such as solids, liquids, and gases. Acoustics also involves the functioning of various musical instruments. Ultrasound and infrasounds are concepts studied in Acoustics.
This branch of physics studies heat and other forms of energy and their relation to their work and energy. The main focus of thermodynamics is the transfer of energy from one place to another. The three laws of thermodynamics laid the foundation of this branch.
Mechanics deals with the motion of any object due to the force acting on it when it was at rest.
However, Mechanics is similar to classical physics as it includes concepts and laws of motion but the force is something that differentiates mechanics and classical physics.
