Electromagnetism – branch of science concerned with the forces that occur between electrically charged particles. Geophysics – the physics of the Earth and its environment in space; also the study of the Earth using quantitative physical methods; Magnetism – the study of physical phenomena that are mediated by magnetic field.
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.
Physics First is an educational program in the United States, that teaches a basic physics course in the ninth grade (usually 14-year-olds), [1] rather than the biology course which is more standard in public schools. This course relies on the limited math skills that the students have from pre-algebra and algebra I.
Physics, as with the rest of science, relies on the philosophy of science and its "scientific method" to advance knowledge of the physical world. [44] 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. [ 45 ]
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.
Chemistry is the scientific study of the properties and behavior of matter. [1] It is a physical science within the natural sciences that studies the chemical elements that make up matter and compounds made of atoms, molecules and ions: their composition, structure, properties, behavior and the changes they undergo during reactions with other substances.
The branch of science concerned with the behaviour of physical bodies when subjected to forces or displacements and the subsequent effects of the bodies on their environment. melting. Also called fusion. A physical process that results in the phase transition of a substance from a solid to a liquid. meson
