Physical science is the research of physics and chemistry of nature. From the materialist and functionalist viewpoints it overlaps the life sciences in which ecology studies the evidences of historical facts or evolution. Natural sciences link the phenomena in the physical sciences to the noumenon within the life sciences.
The foundations of the physical sciences rest on key theories and concepts, all of which explain and/or model a certain aspect of the behavior of nature.
Basic principles of
Physics, along with chemistry and mathematics, classes as
one of the basic sciences because the other natural sciences (like geology,
biology and so on.) cope with systems that appear to obey the laws of physics.
Based on physics, the physical laws of matter, energy and the basic forces of
nature govern the relationships between particles and physical entities (such
as molecules, planets, atoms or the subatomic particles).
Examples of Physical Science
Physical Science is an encompassing word for the branches of
natural science and science which study non-living systems, as opposed to the
life sciences. However, the word physical produces an unintended, fairly
arbitrary distinction, since numerous branches of physical science also study
Astronomy, Earth science,
chemistry and physics are examples of physical science which are studied.
Newton's laws of motion and the theory of gravity are researched in physical
science along with interactions with the Earth, solar system and moon.
