What is Physics?
Physics is the most basic of all the sciences. It is concerned with the study of
systems, forces and energy, the composition of matter and other unforeseen
phenomena. It also involves the laws and principles which govern man’s
interaction with these systems and how he manipulates the system to improve
and maintain mankind’s way of life. In addition, it involves theories which seek
to explain the physical tendencies of the universe. These theories can change
overtime as scientists, through experiments under particular conditions, rewrite
past beliefs with proven facts (a close agreement by scientists who have done
adequate and ongoing research on a particular topic. Models are used to
represent the actual realities. They are used as hands-on material to the extent
to which we are unable to pursue on a day-today basis.
Physics is about the nature of basic things – atoms (and their components),
motion forces, energy, and matter. As a fundamental scientific discipline, all
improvements in technology can be traced either directly or indirectly to
Physics. In essence, all other scientific disciplines spring from this scientific
discipline.
