Physics – natural science that involves the study of matter [1] and its motion through spacetime, along with related concepts such as energy and force. [2] More broadly, it is the general analysis of nature, conducted in order to understand how the universe behaves. [3][4][5]
Einstein's argument for the possible invalidity of SR also works if we ignore questions of structure and merely accept the weaker condition that matter is always associated with curvature (as it must be according to the PoE): SR can then only be an exact solution in the absence of matter (Taylor and Wheeler, Box 3.1: "The Principle of ...
AP courses were first administered by the College Board in the 1955–1956 school year, with AP Physics being one of the ten courses. As college and university physics courses use different levels of mathematics, in 1969, the single AP Physics course was split into AP Physics B and AP Physics C. AP Physics B served as an algebra-based course for life science and medical students, whereas AP ...
Physics – natural and physical science could involve the study of matter [4] and its motion through space and time, along with related concepts such as energy and force. [5] More broadly, it is the general analysis of nature, conducted in order to understand how the universe behaves. [a][6][7] Branches of physics.

Applied physics is the application of physics to solve scientific or engineering problems. It is usually considered a bridge or a connection between physics and engineering. "Applied" is distinguished from "pure" by a subtle combination of factors, such as the motivation and attitude of researchers and the nature of the relationship to the ...
Field (physics) Illustration of the electric field surrounding a positive (red) and a negative (blue) charge. In science, a field is a physical quantity, represented by a scalar, vector, or tensor, that has a value for each point in space and time. [1][2][3] An example of a scalar field is a weather map, with the surface temperature described ...
[1] Some of the major unsolved problems in physics are theoretical, meaning that existing theories seem incapable of explaining a certain observed phenomenon or experimental result. The others are experimental, meaning that there is a difficulty in creating an experiment to test a proposed theory or investigate a phenomenon in greater detail.
