# What are the branches of physics?

• .1: Classical mechanics (studies the behavior of bodies)What are the branches of physics?

Mechanics studies the movement of bodies and the forces that act on them. To do this, it uses Newton’s Laws, and is often applied, for example, in the study of rocket launches. It is one of the main branches of physics. Classical mechanics (studies the behavior of bodies)What are the branches of physics?Mechanics studies the movement of bodies and the forces that act on them. To do this, it uses Newton’s Laws, and is often applied, for example, in the study of rocket launches. It is one of the main branches of physics.

Classical mechanics gave rise to two branches of physics: kinematics and statics.

5. Kinematics (studies the movement of objects)

Kinematics studies and describes the movements of solid objects and their trajectory according to time. Calculate the speed, acceleration and displacement that these can reach. This branch of physics derives from classical mechanics. It is used in various ways, for example, in the study of the motion of a spring.

6. Dynamics (studies the forces applied to moving bodies)

Dynamics studies the causes that generate the movements of bodies and their physical changes in a physical system, such as forces. In these studies, Newton’s laws can be applied, and they are used to calculate the deformation or friction suffered by bodies. His studies derive from classical mechanics.

7. Statics (studies the forces applied to bodies at rest)

Statics is used to study the balance of forces acting on bodies found in a system at rest. That is, its velocity is zero, as is the force of its acceleration. It is part of the study of Newton’s laws and derives from classical mechanics.

8. Fluid mechanics (studies fluids)

Fluid mechanics is the study of the dynamics or behavior of liquids and gases in a state of rest or motion. This branch is applied in studies related to hydraulic or fuel systems, among others.

9. Optics (studies the phenomena of light)

Optics studies light and its behavior, as well as its effects on other bodies and its properties based on light phenomena and light energy. It even studies the vision and perception of light by the human being. Optics is applied, for example, in the development of optical fibers and optoelectronics.

10. Electrostatics (studies bodies with electrical charges)

Electrostatics studies the interactions between bodies with electrical charges when they are at rest. Electric charge is a property of matter and from which various electrostatic phenomena arise, such as the attraction or repulsion of electronically charged bodies. For its study, Maxwell’s laws are applied.

Electrostatics is usually applied, for example, in xerography, a printing technique that allows powdered pigment (color) to be fixed in a charged area.

11. Hydraulics (studies fluids in motion and at rest)

Hydraulics studies the behavior and movement of fluids according to their properties. In this way, the properties of fluids to transmit energy and force that put a mechanism into operation can be established.

For example, the waterwheel is a machine that makes it possible to obtain energy from a source or waterfall.

12. Quantum mechanics (studies matter at the atomic and subatomic level)

Quantum mechanics studies atoms, their properties and interactions, and the behavior of subatomic particles. In this sense, he studies nature from its smallest dimensions. It is applied in various studies, such as the behavior of solid bodies. It is one of the main branches of modern physics.

13. Astrophysics (studies the stars by physical and chemical laws)

Astrophysics studies the bodies found in space, their movements, properties and phenomena. Their knowledge helps us understand how space, stars, galaxies and planets work through the development of astronomical observatories, among others.

14. Biophysics (studies biological processes)

Biophysics is based on the studies of biology and physics to study how various biological processes are carried out in living beings and explain their operation and importance. For example, it allows us to know how energy works in the cell or nerve impulses.

15. Cosmology (studies the universe)

Cosmology studies the laws that govern the universe, its origin and how the forces between the celestial bodies work. Its purpose is to better understand the existence of the universe and determine its future.

16. Atomic Physics (studies the electronic structure in atoms and molecules)

Atomic physics focuses on the study of the atom, its structure, energy states (fission and fusion), the interaction of its particles and its electronic configuration.

17. Nuclear Physics (studies the nuclei of the atom and nuclear reactions)

• Nuclear physics studies the nucleus of the atom, which is made up of different particles, such as protons and neutrons, united by various forces and interactions with each other.What are the branches of physics?

Likewise, this branch of modern physics studies the release of radioactive energy that is generated through atoms, and that results in great impact. Nuclear physics is often applied, for example, in nuclear plants in order to generate energy.

18. Medical Physics (studies medical diagnoses and treatments)

It is a multidisciplinary branch in which the knowledge of physics, biology and medicine are applied. It serves to establish principles and methods to obtain better medical diagnoses and treatments, as well as to prevent various diseases. It is applied in the area of ​​medicine and human health.

19. Molecular Physics (studies the properties of molecules)

Molecular physics studies the physical properties of molecules and the interaction of their atomic structures. It is related to other studies on optics, biology, studies of materials, among others. This branch of physics can be applied, for example, in fundamental studies on the interactions of electromagnetic fields.

20. Geophysics (studies the physical system of the Earth)What are the branches of physics?

It is the science that studies the Earth from the methods and principles of physics, for which it uses the studies of mechanics, electromagnetism, radioactive phenomena, among others. For example, it can be applied to study and identify earthquakes. Geophysics is divided into two branches which are internal geophysics and external geophysics.

21. Meteorology (studies the atmosphere)

Meteorology is a science that studies the atmosphere and its components. It uses the diverse knowledge of physics to study and analyze the weather conditions, meteorological phenomena, the atmosphere, the movements of air and water on the earth’s surface, among others. This branch of physics allows us to make climate predictions.

22. Relativity (studies time and space)

Relativity is part of the theories developed by Albert Einstein. It is used to study physical events considering that time and space are relative and not absolute, since the different points of view of the observers are taken into account.What are the branches of physics?

Einstein’s theories transformed the principles of physics by incorporating the concepts of space and time, as well as studies of gravity, cosmology, and astrophysics, among others.

23. Computational Physics (studies computational models)

Computational physics is used to build computational models. These models are made up of the equations of physical laws known as Newton’s laws, so scientists can simulate gases or clusters of galaxies, among others.

In this case, laboratories are replaced by computers, used as the main work tools to carry out analyzes and mathematical calculations.

Computational physics is applied, for example, to simulate how electrons move in radiotherapy.

24. Statistical mechanics (statistical study of many-particle systems)What are the branches of physics?

Statistical mechanics is the branch of physics that combines the laws of classical or quantum mechanics with statistical hypotheses.

These studies use probability theory to study the behavior of a large set of equal particles or systems, with the aim of obtaining the most probable values ​​of their properties.

Therefore, its purpose is to deduce the macroscopic properties of a matter from its atomic and molecular structure. For example, it can be applied to study the par gas
