10 APPLICATIONS OF PHYSICS IN EVERYDAY LIFE - SCIENCE - 2024

Some of the applications of physics in everyday life are numerous. Some medical tools, such as X-rays for example or laser operations, would not be possible without this branch of science, as well as more everyday objects such as telephones, televisions and almost all electronic devices.

On the other hand, without physics, planes couldn't fly, cars couldn't roll, and buildings couldn't be built. Almost all things relate to physics in some way or another.

Physics has many fields of study whose applications are in the everyday life of humans. The most common are astrophysics, biophysics, molecular physics, electronics, particle physics, and relativity, among others.

Physics is the natural science that involves the study of matter and its movements and behaviors through space and time.

He also studies related concepts, such as energy and force. It is one of the most fundamental branches of the disciplines of science; the greatest goal of physics is to understand how the universe behaves.

10 applications of physics

1- Electromagnetism

This field of physics studies electromagnetic force, a type of physical interaction that occurs between electrically charged particles.

Electromagnetic force is usually exhibited in electromagnetic fields such as electric fields, magnetic fields, and in light. It is one of the four fundamental interactions of nature.

The electromagnetic force plays a large role in determining the internal properties of most objects used in daily life.

Ordinary matter takes its shape as a result of intermolecular forces between individual atoms and molecules in matter, being a manifestation of the electromagnetic force.

The theoretical implications of electromagnetism led to the development of spatial relativity by Albert Einstein in 1905.

All electrical equipment that we use in daily life is related to electromagnetism. From microwave ovens, electric fans, and electric doorbells to alarm clocks.

2- Atomic physics

This field studies atoms as an isolated system of electrons and an atomic nucleus. It is primarily concerned with the arrangement or location of the electrons around the nucleus and the process in which these arrangements change. It also includes neutral ions and atoms.

The term atomic physics can be associated with nuclear power and nuclear weapons, although nuclear physics only deals with the nuclei of atoms.

Generally in scientific fields the broader context among various branches is considered; only scientific studies are that specific.

3- Quantum mechanics

Quantum theory, reconceived in 1920, is the theoretical basis of modern physics that explains the nature and behavior of matter and energy at an atomic and sub-atomic level. This field is called quantum physics or quantum mechanics.

Applications of quantum theory include quantum chemistry, superconducting magnets, lasers, microprocessors, magnetic resonance imaging, and electron microscopes. It also explains many biological and physical phenomena of energy.

Quantum mechanics has been very successful in explaining many of the characteristics of the universe. It is usually the only tool to reveal the individual behaviors of the subatomic particles that make up all forms of matter.

It has also had an influence on string theories, candidates for a Theory of Everything. Many aspects of technology operate at levels where quantum effects are significant.

A large number of electronic devices are designed based on quantum mechanics; lasers, microchips, light switches, pen drives, computers and other telecommunication equipment.

New advancements in the field are working to improve quantum cryptography. Another goal in this field is the development of quantum computers; they are expected to process tasks much faster than classical computers.

4- Theory of Relativity

In his theory of relativity, Einstein determined that the laws of physics are the same for all observers. He also determined that the speed of light is the same, regardless of the speed at which the observer travels.

One of the effects of this theory is that different observers traveling at different speeds can have different perspectives on the same event; however all observations are correct.

This theory is applied in many aspects of everyday life. GPS systems rely on it to function, for example.

Electromagnets are also possible thanks to relativity. Older televisions, or those without plasma screens, also worked with a mechanism based on relativity.

5- Lasers

A laser is a device that emits monochromatic light through an optical amplification process based on the stimulated emission of protons. The principles of laser devices are based on quantum mechanics.

Laser devices have many applications in the areas of science, military, medicine and in the commercial area as well.

Photochemistry, laser scanners, nuclear fusion, microscopes, cosmetic surgery, eye surgery, and dental operations are just a few fields that use lasers as well.

In the commercial industry, they are used for cutting materials, drilling and printing; they are also a source of light for movie projectors.

6- Nuclear physics

Nuclear physics is the field of physics that studies the nuclei of atoms, their constituents and interactions.

Other forms of nuclear matter are also studied. Nuclear physics is not the same as atomic physics, a field that studies the entire atom and its electrons.

Discoveries in nuclear physics have led to its application in many fields. These fields include nuclear power, nuclear weapons, nuclear medicine, industrial and agricultural isotopes, ion implants in engineering materials, and radiocarbon dating.

7- Aerodynamics

This branch of physics studies how air behaves and the relationship it has when an object passes through it.

Without it, aircraft, rockets, cars or bridges could never have been designed to survive hurricanes. Figuring out how to move through a fluid quickly and effectively is the job of aerodynamics.

Air is a fluid and to pass through it quickly, you need to do it in a long, thin vehicle.

In this way, you could create as little resistance as possible to go fast. In the same way that humans advance in the sea faster if they swim horizontally; for this reason planes and trains are tube-shaped.

8- Molecular physics

Molecular physics is the study of the physical properties of molecules, the chemical bonds between atoms, and molecular dynamics.

His most important experimental techniques are the different types of spectroscopy. This field is closely linked with atomic physics and has many things in common with theoretical chemistry, physical chemistry, and chemistry.

This branch of physics measures properties of rotation and vibration of the spectrum of molecules, the distances between the nuclei of molecules and their properties, among other things.

9- Astrophysics

This branch of astronomy combines the principles of physics and chemistry to discover the nature of celestial bodies rather than their positions or movements in space.

Objects of study include the sun, other stars, galaxies, extra-solar planets, and the intergalactic cosmic background.

Its emissions are examined across all parts of the electromagnetic spectrum and the properties examined include luminosity, density, temperature, and chemical composition.

Astrophysics is a very broad field, so astrophysicists typically apply many disciplines of physics such as mechanics, electromagnetism, thermodynamics, quantum mechanics, relativity, nuclear physics, particle physics, atomic physics, and molecular physics.

In practice, modern research involves a lot of observational and theoretical physics work. Some areas of study they are trying to determine include the properties of dark matter, black holes, whether time travel is possible, whether wormholes can form, whether the multiverse exists, and the origin and fate of the universe.

Astrophysicists also study the formation and evolution of the Solar System, the formation of galaxies, cosmic rays, and astroparticle physics.

10- Thermodynamics

This field of physics deals with heat and temperature and their relationship to energy and work. The behavior of these qualities are subject to the four laws of thermodynamics.

Thermodynamics is applied in many branches of science and engineering, especially in pure chemistry, chemical engineering, and mechanical engineering.

Its fields of applications include biological thermodynamics, black hole thermodynamics, psychometry, quantum thermodynamics, and statistical thermodynamics.
