Branches of Physics class 9 chapter 1| part 2. I have have discussed the branches of physics for class 9 in two parts with detail. The first part contain the first five branches of physics and the remaining branches of physics class 9 chapter 1 are discussed in this part 2 in detail. The branches of physics is very basic and important topic on this level because these branches of physics will be studied in the up coming 9th 10th classes. This is the Link of the Lecture which contains five branches of physics.

My name is Muhammad Nazir and this is my channel Lectures of Physics. This Channel contains Lectures on physics of 9th,10th,11th and 12th classes. In this lecture I have discussed in detail about the branches of physics class 9 chapter 1, the remaining branches of physics. They are
1.Atomic and Nuclear Physics
2.Relativity
3.Quantum Physics
4.Particle Physics
5.Cosmology and Astrophysics
6.Biophysics and Medical Physics
All These branches of physics are discussed in detail with examples and applications in this lecture. After watching this video the students will be able to understand the fundamental concepts of physics in matric and FSc level. Besides these branches of physics there are also other branches. But these branches are enough for this level of physics.
The study of structure and properties of an atom is called atomic physics. X rays and LASER technologies are the two important fields of atomic physics. The study of structure and properties of atomic nucleous is called nuclear physics. Nuclear radiations and nuclear weapons are the important fields of nuclear physics.
The study of motion with very high speed is called relativity. The study of light energy in the form of packets of energy is called quantum physics. Similarly the study of fundamental particles is called particle physics.
In cosmology we study the origin and eventual fate of the universe and in Astrophysics we study the heavenly bodies like sun and other stars. Biophysics and medical physics relates the applications of to biological and medical phenomena.
More specifically, atomic physics deals with the atom as a system consisting of a nucleus and electrons. Nuclear physics deals with the nucleus as a system consisting of nucleons (protons and neutrons). Atomic physics concerns itself with the entire atom and how the electronic configuration of electrons can change.
Nuclear physics is the branch of physics that studies atomic nuclei and their constituents and interactions. Examples of nuclear interactions or nuclear reactions include radioactive decay, nuclear fusion and fission. In this article, let us study nuclear physics, nuclear physics theory, nuclear force, and radioactivity in detail.
Special relativity proved how space and time are not fixed and instead part of the same thing. In his general relativity, Einstein showed that the geometry of spacetime is not fixed either. Spacetime is connected to matter: it tells matter how to move and matter tells spacetime how to curve
The Astrophysics and Cosmology group focuses mainly on cosmology (the properties and evolution of the universe and growth of large scale structure), galaxy evolution (how galaxies grow and change over time), and supernovae (causes of TypeIa supernovae, modeling the spectrum of emitted light, use as standard candles to measure the expansion of the Universe). We approach these problems using theoretical, computational, and observational techniques. We are involved with a number of current and upcoming astronomical survey projects which can address these questions.
Quantum physics is the study of matter and energy at the most fundamental level. It aims to uncover the properties and behaviors of the very building blocks of nature.

While many quantum experiments examine very small objects, such as electrons and photons, quantum phenomena are all around us, acting on every scale. However, we may not be able to detect them easily in larger objects.
These are the branches of physics. If you have any question about the branches of physics, you can ask in the comment box.
