Welcome to Physics Wiki! We are currently editing over 173 articles, and you can help "Physics is the branch of science that deals with the structure of matter and how the fundamental constituents of the universe interact." - Encyclopedia Britannica "The branch of science concerned with the nature and properties of non-living matter and energy, in so far as they are not dealt with by chemistry or biology; the science whose subject matter includes mechanics, heat, light and other radiation, sound, electricity, magnetism, gravity, the structure of atoms, the nature of subatomic particles, and the fundamental laws of the material universe." - Oxford English Dictionary

Physic Wiki The purpose of this wiki is to provide articles on physics concepts as well as provide everyone from physics graduate students to casual readers with peer-reviewed problems and solutions. Many of these problems are graduate-level, from public problem banks. Public problem banks are often compiled by various university physics departments and include questions that they have given on previous PhD qualifying/prelim exams. The community can submit problems, search for problems, and post or correct solutions to these problems.

Topics Classical physics Kinematics - the study of the motion of objects Dynamics - the study of the forces and torques which cause motion of objects Electromagnetism Gravitation Thermodynamics - the study of heat and energy transfer Optics - the study of light and its interactions with matter Modern physics Quantum mechanics - describes the behavior of nature at and below the scale of atoms. Particle physics - study of fundamental particles and forces that constitute matter and radiation. Special relativity - the theory relating space and time, which states physical laws and constants are independent of reference frame General relativity - the theory relating spacetime to gravitation

Newton's law of universal gravitation

$F= \frac{G m_1 m_2}{r^2}$

Gravity is a fundamental interaction which causes mutual attraction between all things that have mass. It is the weakest of the four fundamental interactions, yet one of the most easily observed. It is the most significant interaction between objects at the macroscopic scale, and it determines the motion of planets, stars, galaxies, and even light. Read More
