WHAT IS PHYSICS
Physics was formerly called natural philosophy, it is concerned with those aspects of nature which can be understood in a fundamental way in terms of elementary principles and laws. In the course of time, various specialized sciences broke away from Physics to form autonomous fields of investigation. In this process, Physics retained its original aim of understanding the structure of the natural world and explaining natural phenomena.
The most basic parts of Physics are
mechanics and field theory. Mechanics is
concerned with the motion of particles or
bodies under the action of given forces. The Physics of fields is concerned with the origin, nature and properties of gravitational, electromagnetic, nuclear and other force fields. Taken together, mechanics and field theory constitute the most fundamental approach to an understanding of natural phenomena which science offers.
In other words, Physics can be defined or summarizes as a physical science that deals with the behaviour of matter in relation to energy. Also it be said to be science of measurement
REASONS OR BENEFTIIS FOR
The study of Physics enables us to:
i) Acquire scientitic Knowledge and
ii) Be self suficient in our present day society.
(iii) Have ability to make our country and
perhaps the whole world a beter place to live in.
(iv) Pass our examination and to get a
good job at the end of our study.
In line with this numerous benefits,
Physics is characterised by accurate
Instrumentation, precision of
measurement, and the expression of iits results in mathematical terms.

Accelerator Physics: Is a branch of
applied physics concerned with
designing, building and operating
particle accelerators. A particleaccelerator is a device that uses clectromagnetic fields to propel charged particles to high speeds and to contain them in well-defined beams.
Acoustics: It is the interdisciplinary
SCience that deals with the study of
a mechanical waves in gases, liquids, and solids including vibration, sound, ultrasound, and infrasound. A scientist who works in the field of acoustics Is an acoustician, while someone working in the field of acoustics technology may be called an acoustical engineer.
Agro Physics: Is a branch of science
bordering on agronomy and physiCs,
whose objects of study are the agro ecosystem- the biological objects,
DIotope and biocoenosis affected by
human activity, studied and described
using the methods of physical sciences.
Biophysics: Is an interdisciplinary
sCience using methods of, and
theories from physi cs to study
biological systems. Biophysics spans
all levels of biological organisation trom the molecular scale to whole organisms and ecosystems.
Chemical Physics: Is a sub-discipline
of chemistry and physics that
investigates physiochemical phenomena using techniques from atomic and
molecular physics. It 1s the branch of
physics that studies chemical processes
from the point of view of physics.
Communication Physics: Is one of the
applied branches of physics. It deals with various kinds of communication systems.
Econo-Physics: Is an inter-disciplinary
research field, applying theories and
methods originally developed by physicians in order to solve problems in economics.
Engineering Physics: Is the study of
the combined disciplines of physics, engineering and mathematics in order to develop an understanding of the inter relationships of these three disciplines.
Geophysics:Is the physics of the earth
and its environment in space, also the
study of the earth using quantitative
physical methods. The tem geophysics
sometimes refers only to the geological
applications, earth shape, its gravitational
and magnetic fields, its internal structure
Laser Physics: Is a branch of optics
that describes the theory and practice
of lasers. Laser science is principally concerned with quantum electronics,
laser construction, optical cavity
design, the physics of producing a
population inversion in laser medicine and the temporary evolution of the light field in the laser. It is also concerned with the physics of laser beams propagation.
Material Physics: is the use of physics
to describe materials in many different
ways such as force, heat, light, and
mechanics. It is a synthesis of physical
sciences such as chemistry, solid
mechanics and solid state physics.
Medical Physics: lt is the application
of physics concepts, theories and
methods to medicine or health care.
Medical physics department may be
found in hospitals or universities.
Solderingls a branch of physics which
deals with the joining of metals by the
use of a solder alloy, made by combining
tin and lead in difterent proportions.
Broadcasting: ls a branch of physics
which deals with different
distribution of audio, video, content to a dispersed audience via any audio or
Visual mass communications medium,
but usually only using the electromagnetic radiation (radio-
Computer Programming: is a branch
of physics which deals with the
collections of computer programs and
related data referred to as the sottware.
Radiography: ls an imaging technique that uses electromagnetic radiation other
than visible, especially x-rays, to view
the intermal structure of a non-uniformly
composed and opaque object. Such as
the human body. Metallurgy1s a domain of materialsscience and materials engineering that study the physical and chemical behaviour of metallic elements, there intermetallic compounds, and there
mixture which are called alloys.
Metallurgy is also the technology of
metals; the way in which science is
applied to the production of metals,
and the engineering of metal components for use in products for consumer and manufacturers.
Quantity Survey: It is a branch of
physics that deals with construction
costs and contracts. The services provided by the quantity surveyor include cost planning and commercial
management during the entire life
cycle of the project from inception to completion.
Metrology: Is the science of
measurement. Metrology includes all the
theoretical and practical aspects of measurements.
Pharmacy: is the science and technique
of preparing as well as dispensing drugs
and medicines. It is a health profession that links health sciences with chemical sciences and aims to ensure the safe and
effective use of pharmaceutical drugs.
System Engineering: Is an
interdisciplinary field of engineering
that focuses on how to design and
manage complex engineering
projects over their life cycles. System
engineering techniques are used in
complex projects space craft design robotics etc.
