[6] Diagram showing how an exoplanet's orbit changes the position and velocity of a star as they orbit a common center of mass. In many binary stars, the orbital motion usually causes radial velocity variations of several kilometres per second (km/s). As the spectra of these stars vary due to the Doppler effect, they are called spectroscopic ...
imaginary unit: unitless electric current: ampere (A) ^ Cartesian x-axis basis unit vector unitless current density: ampere per square meter (A/m 2) impulse: kilogram meter per second (kg⋅m/s) jerk: meter per second cubed (m/s 3)
A multiple choice question, with days of the week as potential answers. Multiple choice (MC), [1] objective response or MCQ(for multiple choice question) is a form of an objective assessment in which respondents are asked to select only the correct answer from the choices offered as a list.
In physics, there are equations in every field to relate physical quantities to each other and perform calculations. Entire handbooks of equations can only summarize most of the full subject, else are highly specialized within a certain field. Physics is derived of formulae only.
Before the 2024–25 school year, the multiple choice and free response section were each allotted 45 minutes, with 35 questions for the former and 3 questions for the latter. This made AP Physics C: Mechanics, along with Electricity and Magnetism, the shortest exams offered by College Board.
astrophysics, the physics in the universe, including the properties and interactions of celestial bodies in astronomy; atmospheric physics is the application of physics to the study of the atmosphere; space physics is the study of plasmas as they occur naturally in the Earth's upper atmosphere (aeronomy) and within the Solar System
[6] [7] [8] Homeokinetics – the physics of complex, self-organizing systems; Continuum mechanics – the branch of mechanics that deals with the analysis of the kinematics and the mechanical behavior of materials modeled as a continuous mass rather than as discrete particles. Dynamics – the study of the causes of motion and changes in motion
