Introduction to
Physics
The word Science is derived
from Latin word “Scientia” meaning Knowledge. So the knowledge gained through observations and
experimentations is called Science. In 19th century, Science was divided into
two types; Physical Sciences and Biological Sciences. Physical sciences deals
with the study of non-living things and Biological Sciences deals with the
study of living things. So, Physics is the branch of Physical Sciences.
Physics: “The study of matter and energy and the relationship
between them is called Physics.”
The study of Physics involves
investigating things such as laws of motion, the structure of space and time,
the nature of type of forces that hold different materials together, the
interaction between different particles etc.
Physics is most fundamental
of all sciences and provides other branches of science, basic principles and
fundamental laws. The overlapping of physics and other fields gave birth to new
branches such as physical chemistry, biophysics, astrophysics, health physics
etc. Physics also plays an important role in the development of technology and
engineering.
