Physics is the study of science of matter and its motion or we can say that science that deals with concepts such as energy, force, mass, and charge.

The science of experimenta basil has a goal that is to understand the natural world.

In one or the other form subject physics is one of the oldest disciplined academics through its subfield which is modern of astronomy. It may be considered as the oldest of all.

Synonymous with philosophy or chemistry and even with certain branches of biology and mathematics during the last two millennia this subject has emerged as a modern science in the 17th century and these disciplines are distinct, although to define the boundaries remain difficult. 

The technologies which are in subject physics that often translate to the technology sector. And sometimes these influences which are mentioned are the other sciences fields as well. For example if we say about philosophy and mathematics.

There are a lot more factors which ultimately have these solutions. In today's scenario the subject physics is a high and broad developed subject.

Often the Research which is divided into four subfields that is condensed matter of physics. The atomic and molecular physics of optical has high energy physics , astrophysics and astronomy.

Most of the physicists specialize in either experimental or theoretical  research, the formal dealing with the development of theories which are new, and the latter is dealing with the testing of experimental theories and the discovery of new phenomena as well.

Despite so many important discoveries during the centuries, there are a number of open questions in the subject like physics, and many areas which are of active research as well.


Physics normally deals with the combination of energy and matter. It deals with a wide variety of systems which is about the theories. That has been developed and it is used by physicists as well.  These so called "central theories" are very important tools for the purpose of research in more specialized topics, and any physicist which is regardless of his or her specialization, this whole thing is expected to be literate in all amongst them.

Few Topics 

The mechanics which is said as the Classical mechanics is a model of the physics which forces on acting upon bodies like it includes sub-fields to describe the behaviors of gases and solids and fluids as well. It is often known as "Newtonian mechanics" after the name of sir Isaac Newton and his motions laws. It also includes the approach as given by lagrangian and Hamiltonian methods. These all are associated with the motion of particles which have a general system within them.

There are so many branches which are of classical mechanics, for example such as: dynamic, statics, kinematics and continuum mechanics which generally includes fluid mechanics that is also known as statistical mechanics.

Mechanics can also be defined as a branch of physics in which we study about the properties of the object  also which is in the form of a motion under the action of the force.

Overview of Thermodynamics 

The first chapter of The lecture of Feynman Lectures on subject Physics is about the atoms existence, which is considered as Feynman which is being the most compact  physics statement, from which the field science could easily result if all knowledge was lost. The study of thermodynamics effects of changes which are in pressure and temperature and volume on systems of physical on the scale macroscopic, and the transfer of heat energy. Long ago developed Thermodynamics was developed out of the desire to increase the efficiency of early engines which are of steam.


In 1905 the theory of special relativity was proposed by the great scientist Albert Einstein in his article which was named as "On the Electrodynamics of Moving Bodies". The article's  title refers to the fact that relativity theory which is special resolves an inconsistency between Maxwell's equations and classical mechanics as well. The theory is based on two postulates which are- mathematical forms laws of physics and are invariant in all inertial systems and the second one is  that the light speed in a vacuum is constant and independent of the observer and source. Looking at the two postulates we can see that it requires a unification of time and space into the frame-dependent concept.

Quantum Mechanics

The equation of Schrödinger plays the very important role in quantum mechanics that law of Newton's and conservation of energy serve in classical mechanics.

For example electromagnetic or light radiation which is emitted or absorbed by an atom has only certain frequencies or even the wavelengths, as can be seen from the line which is spectrum associated with the elements of chemical which are represented by that atom.

FAQ (Frequently Asked Questions)

Q1. Mention the 7 Branches of Physics?

Q2. What are the Different Branches of Physics, Explain with Definition?

Ans: The science branch of science which deals with the interaction of energy and matter is called physics. There are Two Major Branches of Physics that are Modern and  Classical Physics. Further physics sub branches are electromagnetism, Mechanics, Thermodynamics, Optics.

Q3. Name the Five Branches of Physics?

Ans: The five major branches of physics are:

  1. The Classical mechanics.

  2. Statistical mechanics and Thermodynamics.

  3. Electronics and Electromagnetism.

  4. The Relativity theory 

  5. Quantum mechanics.

Q4. Explain Who Had Named Physics?

Ans: The History of the subject Physics which was given  Before Aristotle that is natural law and Atomism. Thales was known as the first physicist and his theories were actually given the discipline its name. He believed that the whole world, fashioned from many materials that was really built of only one element, was water that is called Physis in Ancient Greek.
