Physical science is an encompassing term for the branches of natural science, and science (generally), that study non-living systems, in contrast to the biological sciences. However, the term "physical" creates an unintended, somewhat arbitrary distinction, since many branches of physical science also study biological phenomena. Note that mathematics is not a physical science.

any principles of experimentation developed in the physical sciences have been adopted and built upon in the science of psychology.

Basic physical science topics of interest to psychologists include include:

The branches of physical science:

  • Chemistry - the science dealing with the composition of substances, their interactions with energy and each other
  • Physics - the quantitative science dealing with matter and energy

Basic principles of the physical sciences

The foundations of the physical sciences rests upon key concepts and theories, each of which explains and/or models a particular aspect of the behavior of nature. As in other sciences, these key concepts and theories came to discovery using the scientific method, which must be found using scientific evidence:

Basic principles of chemistry

Chemistry is the science of matter mainly at the micro-level. Its studies include the following:

Basic principles of physics

Physics is the "fundamental science" because the other natural sciences (biology, chemistry, geology, etc.) deal with systems that obey the laws of physics. The physical laws of matter, energy, and the forces of nature govern the interactions between particles (such as molecules, atoms, or subatomic particles). Some basic principles of physics are:
