Scientific modelling is an activity that produces models representing empirical objects, phenomena, and physical processes, to make a particular part or feature of the world easier to understand, define, quantify, visualize, or simulate.
The AP Physics 2 classes began in the fall of 2014, with the first AP exams administered in May 2015. The courses were formed through collaboration between current Advanced Placement teachers and The College Board, with the guidance from the National Research Council and the National Science Foundation.

Meanwhile, AP Physics 2 covered the other content areas. In 2020, the sound, waves, and electricity topics were removed from AP Physics 1 and moved to AP Physics 2. In 2024, the unit covering fluids was moved from AP Physics 2 to AP Physics 1, making space in the AP Physics 2 curriculum for more detail on waves and modern physics. [2] [7]
After the publication of Bell's paper, a variety of experiments to test Bell's inequalities were carried out, notably by the group of Alain Aspect in the 1980s; [26] all experiments conducted to date have found behavior in line with the predictions of quantum mechanics. The present view of the situation is that quantum mechanics flatly ...
Four separate subexperiments are conducted, corresponding to the four terms E(a, b) in the test statistic S (equation (2) shown below). The settings a , a ′, b and b ′ are generally in practice chosen to be 0, 45°, 22.5° and 67.5° respectively — the "Bell test angles" — these being the ones for which the quantum mechanical formula ...
Scientific realism is the view that the universe described by science is real regardless of how it may be interpreted. A believer of scientific realism takes the universe as described by science to be true (or approximately true), because of their assertion that science can be used to find the truth (or approximate truth) about both the physical and metaphysical in the Universe.
In particle physics, the coincidence method (or coincidence technique) is an experimental design through which particle detectors register two or more simultaneous measurements of a particular event through different interaction channels. Detection can be made by sensing the primary particle and/or through the detection of secondary reaction ...
The heavily computational AP Physics B course served as the College Board's algebra-based offering for four decades. As part of the College Board's redesign of science courses, AP Physics B was discontinued; therefore, AP Physics 1 and 2 were created with guidance from the National Research Council and the National Science Foundation.
