Classical physics is the ideal one to solve all technical problems of a human nature, as well as to explain the structures of the solar system and the universe offering answers that do not satisfy to all cosmological doubts.
Today we wanted to give you very complete information about classical physics so that you can have a much more real notion about the different questions that arise around this wonderful science.
Classical physics
This term is used to refer to the physics that existed before the appearance of quantum mechanics, including different branches of study such as thermodynamics, optics, acoustics, electromagnetism among others. Classical physics is also called the one existing before 1900 and modern physics includes the years 1900 onwards, the arrival of quantum mechanics gave the considered classical physics a new perspective.
Modern physics
To make a parenthesis before proceeding to explain the different branches of classical physics, it is necessary to differentiate it from modern physics.
Max Planck starts his "how much" investigations energy at the beginning of the XNUMXth century, which explained that they consisted of energy particles that are not divisible.
It is then that this new branch of physics was born that seeks to study the variations that exist in atoms, the different behaviors that happen to matter and the forces that govern both. Modern physics studies the phenomena that occur at the speed of light or values that approach it.
Likewise, the emerging problems could not be solved with approaches from classical physics, for this it was necessary to be able to rethink investigations and premises of classical physics and adapt the term of modern physics to the studies and theories corresponding to the area.
What are the branches of classical physics?
For a better study of science, its main branches have been classified over time, thus, the human being has been able to perform better in these areas in an optimal way and communicate to the world the new advances in these studies.
Acoustics
The human ear is designed to perceive waves, they must be subjected to a study process that demonstrates their lengths and capabilities. That is why acoustics was born, this branch of classical physics is in charge of study all wave vibrations in order to be finally interpreted as sounds.
The study of acoustics involves music, geological, submarine and atmospheric phenomena, in general terms, this branch of physics is in charge of studying the sounds that are emitted in the terrestrial field.
On the other hand, this presents the psychoacoustics, which is responsible for studying the physical effects that arise in biological systems.
Spring Suspension
This branch is related to physical bodies when they are subjected to displacement forces and, of course, the effects that arise when subjected to these forces.
It is considered a sub-discipline that deals with the study of physical phenomena that occur to objects that are subjected to the physical forces, of the particles that are in a state of rest or in motion but significantly less than the speed of light.
Electromagnetism
Magnetism and electricity come from electromagnetic forces, it is then that electromagnetism is the branch of classical physics that describes how the process of interaction between electricity and magnetism.
To know this branch in depth, it is necessary to emphasize that the magnetic field is created through an electric current in motion, and said magnetic field is capable of induce electric current or failing that, cargo movement.
Mainly, in its origins, electromagnetism was considered as the study of the phenomena that occurred around lightning and the radiation that was produced as a light effect.
Likewise, magnetism was able to be present in objects such as compasses to guide the way, in the past it was used for this purpose.
The phenomenon of particles at rest was observed mainly by Roman culture who, seeing how an effect arose when rubbing a comb, attracted new particles. In summary, it was concluded that positive charges repel and opposites attract.
Fluid mechanics
This branch of classical physics studies the existing flow of liquids and gases, from this branch others emerge sub disciplines such as hydrodynamics and aerodynamics.
Fluid mechanics is applied in the following disciplines: calculation of forces applied to airplanes, mass of oil fluid, prediction of climatic factors.
Optics
This branch of classical physics deals with the study of visual phenomena and light properties including possible interactions of it with matter.
It describes all the processes that occur in visible, ultraviolet, and infrared light. This is because light is primarily an electromagnetic wave like x-rays, microwaves, and radio waves themselves that present similar waves.
This branch is essential for many disciplines who are in charge of studying phenomena associated with it, such as medicine, photography, astronomy and engineering.
Thermodynamics
We continue with thermodynamics, this branch of physics studies the effects of work, energy and heat in a specific system. It is a branch of physics relatively new since it was born in the XNUMXth century with the birth of the steam engine. In short, thermodynamics is responsible for observing and measuring the different phenomena that occur.
The small gas interactions that occur on this scale are called or described by the kinetic theory of gases. They are terms that are related to each other to complement the methods that describe thermodynamics or kinetic theory. There are three laws that govern thermodynamics and they are Enthalpy Law, which leads to the entropy law and therefore the third is born, which is the zeroth law.
