Science is a universal subject that spans the branch of knowledge that examines the structure and behavior of the physical and natural world through observation and experiment. [9] Science education is most commonly broken down into the following three fields: Biology, chemistry, and physics.
Physics, as with the rest of science, relies on the philosophy of science and its "scientific method" to advance knowledge of the physical world. [86] The scientific method employs a priori and a posteriori reasoning as well as the use of Bayesian inference to measure the validity of a given theory. [ 87 ]
Ninth grade (also 9th grade or grade 9) is the ninth or tenth year of formal or compulsory education in some countries. It is generally part of middle school or secondary school depending on country. Students in ninth grade are usually 13-15 years old, but in some countries are 15–16.
Note that neither the names nor the symbols used for the physical quantities are international standards. Some quantities are known as several different names such as the magnetic B-field which is known as the magnetic flux density , the magnetic induction or simply as the magnetic field depending on the context.
Physical chemistry, in contrast to chemical physics, is predominantly (but not always) a supra-molecular science, as the majority of the principles on which it was founded relate to the bulk rather than the molecular or atomic structure alone (for example, chemical equilibrium and colloids).
However, the term "physical" creates an unintended, somewhat arbitrary distinction, since many branches of physical science also study biological phenomena (organic chemistry, for example). The four main branches of physical science are astronomy, physics, chemistry, and the Earth sciences, which include meteorology and geology.
