Children studying in school are taught physics, chemistry and biology together in science. But after passing the tenth class, all the subjects are taught separately from the 11th and their examination is also taken separately. Suppose if a child has decided to study Science for 10+2, then it is mandatory for him to study Physics and Chemistry. Apart from these subjects, one can choose between Mathematics and Biology or can study both the subjects. Mathematics is necessary for the calculation of any quantity, but the events that happen around in our life are taken under physics.
You must have heard about the Space Institute, NASA and ISRO, which do some new mission every year and send spacecraft, satellites etc. to do research in space outside the Earth. Physics plays a very important role in all these missions. If humans did not have the knowledge of physics, then today we would not be able to fly in an aeroplane, neither could electricity be generated nor could we drive vehicles. You just understand that just as mathematics is everywhere, in the same way all the work that is done, physics is hidden in all of them. There are countless such things that we find out through it and we do not even know why it happens. Even though we are unaware of many things but in reality physics is working there. Now let us know what physics.

| What is Physics |
What is Physics and it's Definition ?
Physics is the branch of science in which the natural phenomena occurring in the Universe in general are analyzed and understood. Physics is the science that studies matter and energy and it is a very old and widely spread field of study. Most of the people hear the word Physics and get scared. But it's not just for rocket scientists. In fact everyone is surrounded by this. You use it every day even if you don't realize it.
When you think about physics, one thing comes to mind that it has many scientific laws which have been repeatedly tested and confirmed and phenomena have been created to describe these statements. Physical phenomina is an important part of physics in reality. Its scientists sometimes repeat experiments, explaining how these laws and how our universe works. These laws, such as gravitation and Newton's laws of motion, are so thoroughly tested that they are accepted as true and can be used to help us predict how other things will behave.
Physics tells us the explanation of natural phenomena in the universe, so it is often considered the most unique science. It forms a basis for all other sciences i.e. without physics biology, chemistry or anything else cannot be done.
Who is the father of physics?
The father of physics is Galileo Galilei. If we talk about the father of physics, it mentions Galileo Galilei, Newton and Albert Einstein. Newton and Albert Einstein have given many theories about physics and they have done many experiments, both of which have more than 95% share in physics, but the knowledge of elementary physics and the discovery of elementary physics was made by Galileo Galilei. That is why Galileo Galilei is called the father of physics.

Branches of Physics
As science developed, new branches also developed in it.
Classical Physics:
The branch of science in which Sir Isaac Newton and James Clark Maxwell's Law of Motion and Gravitation are described. This branch mainly deals with the laws of matter and energy. Often physics that dates back to 1900 is referred to as classical physics. And after that it is known as Modern Physics.
In classical physics, energy and matter are referred to as separate quantities. There is a traditional branch under Acoustics, Optics, Classical Mechanics, and Electromagnetic Traditional. Apart from this, whatever its principle is considered to be null, it is automatically labeled under classical. Newton's laws are one of the most important features of classical physics.
Modern physics
Modern physics is the branch of physics that deals primarily with the theory of relativity and quantum mechanics. Albert Einstein and Max Plank were the pioneers of modern physics. Because these people were the first scientists who brought the Theory of Relativity and Quantum Mechanics Responsibly to the world.
Energy and matter are not considered separate NTTs in modern physics. Rather, they are considered to be different forms of each other.
Nuclear physics
Nuclear physics is such a branch of science that deals with the components, structure, behavior and interactions of atomic nuclei. This branch of physics is not to be confused with atomic physics. In which the atom is studied completely with its electrons.
According to the Microsoft Incarta Encyclopedia, nuclear science is defined as follows.
"The branch of physics in which the structure, courses, and behavior of the atomic nucleus are studied."
Nuclear physics has become a very wide area in the modern age and it has become a lot of scope and it is also being used in many fields. It is also being used for power generation, nuclear weapon, medicine, magnetic resonance, imaging, industry, agricultural isotopes.
Mechanics
Mechanical physics is a branch that deals with the motion of objects under the influence of forces. Often it is known only by the name of Mechanics, there are also two branches inside it.
classical mechanics
quantum mechanic
Classical mechanics is concerned with the motion of objects and the forces that cause them to move while quantum physics is the branch that deals with the behavior of the smallest particles i.e. electrons, protons and neutrons.
Acoustics
The word "acoustics" is derived from the Greek word akouen, which means "to hear." Therefore, we can define acoustics as a branch of this that studies how sound is produced, transmitted, received and controlled. Acoustic is also concerned with the effect of sounds in various mediums (ie gas, liquid and solid).
Atomic physics
Atomic is a branch that deals with the structure of the atom. It is mainly concerned with the arrangement and behavior of electrons in the shells surrounding the nucleus. Thus, atomic science mostly investigates electrons, ILOs and neutral atoms.
In the early stages of atomic physics, it was recognized that all matter is made up of atoms. Beginnings, including the atomic ones, are identified with the discovery and understanding of spectral lines. This has made it easier to understand how atoms are structured and how they behave.
Geophysics
Geophysics is a branch that deals with the study of the Earth. It mainly deals with the structure, shape of the earth but geophysicists also study about gravitational force and earthquake magma etc. Geophysics was recognized as a separate discipline from the 19th century, but its origin is considered to be since the magnetic compass was created.
Biophysics
According to the Microsoft Incarta Enclopedia, biophysics is defined as, “The end-subject study of biological phenomena and problems using the principles and techniques of physics is called biophysics. Using the techniques derived from it, studies the biological problems of organisms and the structure of molecules in organisms. One of the most groundbreaking achievements in biophysics is the discovery of the structure of DNA by James Watson and French Crick.
Thermodynamics
Thermodynamics is a branch of physics that deals with the study of hits and temperatures and their relation to energy and work. These points are governed by the 4 laws of behavior thermodynamics.
Astrophysics
The word Astrophysics is made up of two Latin words. Astro means star (star) phi and phisis means nature. Thus astrophysics can be defined as a branch of astronomy that deals with the study of the universe i.e. stars, galaxies and planets by using its laws.
Optics
Optics is a branch of science that studies the interaction of electromagnetic radiation (such as light and infrared radiation) with its substances and the instruments used to obtain information by interaction.

History of Physics
Thales was the world's first physicist and his theories actually gave the discipline its name. He believed that the world is made up of many things. Whereas in reality it is made of only water which was also called Physis in ancient Greek.
When water interacts with the solid liquid and gas face of the material, it creates different properties. They explain natural incident as a phenomenon of science.
Anaximander is famous for his pro-table culinary theory, which disputed Thales's ideas and suggested that the entire universe is made up of building blocks called apirons, rather than water. From today's scientific research, we can say that it was the same idea in a way, as you have hydrogen as the building block in the formation of all matter in our universe.
Heraclitus (about 500BC) proposed that there is only one law governing the universe, which is known as the Principle of Change. According to this, nothing is always the same. Because of this observation, he became one of the greatest scholars of science at that time, which was the most important concept in the history of the roll of time in the universe.
Archimedes, we know it because of his eureka moment, who discovered the principal of density and buoyancy and that too while he was enjoying a bath. But his contribution to the history of this was very deep. His ancient physics was closely associated with the gift of his invention because he made use of the mathematics article principal which is still common today.
Archimedes calculated the underlying mathematics of the lever and developed the rule of moving large objects from one place to another by applying less force. When he did not invent any new devices, he improved upon them and set the principles that allowed the creation of sophisticated machines. He developed the principles of the Principles of William State and the Center of Gravity Ideas, which also influenced Islamic scholars, Galileo and Newton.
The last, and one of the most famous of the ancient physicists, was Ptolemy. This scientist and astronomer was one of the leading minds of the time of the Roman Empire. He wrote many treatises and books, including the works of earlier Greek minds, including Hipparchus's, and he also determined the motion of the sky by calculating some sophisticated calculations.
His work and name spread all over the world in ancient science, through which the knowledge of the Greeks was given to the great Islamic scholars of the medieval period.
Certainly, the contributions of the ancient Greeks directed the course of its history, refining the mathematics that underlie the universe, and opening the distinction between theology and science. His knowledge of this subject of ancient science will soon be forgotten in Europe because science, and especially the study of this subject, has spread to Islamic houses and the great minds of China and India.
Importance of Physics
As we have already known that this subject is that branch of science in which we study about matter and energy as well as read about their interaction now. It holds great importance in the life of mankind.
Physics is a subject that inspires people a lot, it encourages people to understand and get information about nature. There is such a branch of science in which fundamental knowledge helps in advancing the technology of the future.
Because of this branch, today we have been able to send rockets to space and every day countless people in airplanes go from one place to another in just a few hours.
Today we see tall buildings being built in different parts of the world, in which we cannot deny the law of this science. Because high buildings are built following the rules of this to protect them from the calamities coming from nature. That is, how can high-rise buildings be safe in the event of storms, earthquakes, etc., for this, only this science is resorted to.
This subject is an important element for the education of chemistry, engineers, computer scientists, as well as for biomedical and practitioners of this science.
With the help of this science, our life has improved a lot. What is it used for in medical applications, such as ultrasonic, laser surgery, etc.
