Introduction to the chapter
Physics is the study of the Science of matter and its motion or we can say that Science deals with concepts such as Energy, force, mass, and charge.
The Science of experimental basil has a goal that is to understand the natural world.
In one or the other form, 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 talk about Philosophy and Mathematics.
There are a lot more factors which ultimately have these solutions. In today's scenario the subject Physics is a highly developed subject.
Often the Research which is divided into four subfields 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.
Branches
Physics normally deals with the combination of Energy and matter. It deals with a wide variety of systems which are about 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 , regardless of his or her specialization, this whole thing is expected to be literate in all of them.
Few Topics
The Mechanics which is said as the Classical Mechanics is a model of the Physics which forces 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.
Classical Mechanics
Classical Mechanics is a model of the Physics of forces acting on bodies that contains sub-fields for solids, gases, and fluids. After Isaac Newton and his rules of motion, it is commonly referred to as "Newtonian Mechanics." The classical approach, as defined by Hamiltonian and Lagrange methods, is also included. It is concerned with particle mobility and the general system of particles.
Classical Mechanics has several branches, including statics, dynamics, kinematics, continuum Mechanics (which includes fluid Mechanics), statistical Mechanics, and so on.
Mechanics is a field of Physics that studies the item and its attributes as a motion under the influence of a 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 changes in pressure and temperature and volume on systems of Physics on the scale macroscopic, and the transfer of heat Energy. Long ago Thermodynamics was developed out of the desire to increase the efficiency of early engines which are of steam.
Mechanics
In 1905 the theory of special relativity was proposed by the great scientist Albert Einstein in his article "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 vaccum 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 Newton's law 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.

3. Name the Five Branches of Physics?
The five major branches of physics are:
The Classical mechanics.
Statistical mechanics and Thermodynamics.
Electronics and Electromagnetism.
The Relativity theory
Quantum mechanics.
4. Explain Who Had Named Physics?
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.
5. What are the applications of Physics in real life?
Physics , or the study of matter, Energy, and their interactions, aids our understanding of the physical world's laws and norms. Not every student will go on to study Physics at a higher level as they grow older, but everyone uses basic Physics concepts to get around in their daily lives.
Although studying Physics may appear daunting, many of the concepts are likely to be familiar to students. Giving children examples and concepts that will make them feel both interested and thrilled to learn about the "how" and "why" behind things is the first step in combating a negative or frustrated attitude.
Clock with an alarm
From the moment you wake up in the morning, Physics is involved in your daily life. An alarm clock buzzing sound assists you in waking up on time in the morning. The sound is something you cannot see, but you can hear or feel. The origin, propagation, and properties of sound are studied in Physics . It is based on the Quantum Mechanics notion.

6. Why is it important to study Physics ?
Physics aids us in comprehending the world around us, identifying quantifiable physical laws for all phenomena, providing a wide perspective on any topic, and satisfying our curiosity.
As it is interconnected with the other Sciences, Physics is one of the oldest and most complex Sciences. Physics is the study of everything that happens in the universe, including particles, natural events, and Energy, as well as their interactions. Precision is a hallmark of Physics , which drives scientists to develop new tools and procedures to ensure the correctness and outcomes of physical investigations.
7. Why are Physics and Mathematics considered twins of the Sciences?
In the Sciences, Physics and Mathematics cross, and the two are considered twins. The majority of natural occurrences, as well as their diverse behaviours, must be translated into crucial Mathematical equations and formulae that serve human requirements and forecast these phenomena. As a result, it is concluded that Mathematics and Physics are inextricably linked.
Physics is organised into a large number of branches, each of which focuses on a different aspect of the subject. Atomic and nuclear Physics , acoustics, optics, astronomy, geoPhysics , thermodynamics, and many more fields of Physics are among the most well-known.
A great number of scientists from all around the world have contributed to this vast field of knowledge, which has advanced Physics to the point where it is now.
8. How to learn Physics with ease?
Learning Physics may appear difficult, but it is actually a lot easier than we think because Physics is essentially a search for answers to questions that have perplexed the human intellect throughout history.
Physics seeks to comprehend the cosmos and its bizarre events first and foremost. In most cases, the human mind picks up the initial questions through observation, which his thinking later refines into mature questions that lead the world in its search for truth, culminating in the amazing discovery of the answer to the question, or perhaps other answers, or perhaps new questions.
To learn Physics , you must first recognise that it takes a lot of effort to understand it, in addition to the fact that you will need to learn a lot of different things in the fields of natural Sciences, computers, engineering, and other fields in order to comprehend physical theories and learn about their current applications.
9. What topics should be learnt to ace in the subject of Physics ?
It is a good idea to start with some fundamental Math topics like calculus, linear algebra, solving differential equations, learning about complex numbers, statistics and probability, and some special functions, followed by classical Mechanics, optics, thermodynamics, solar system, electromagnetic theory, special theory of relativity, Quantum Mechanics, statistical Mechanics, and solid-state Physics , and finally advanced Mathematics, nuclear Physics , general relativity, and astrophysicists.
