Free energy may refer to: In science: * Thermodynamic free energy, the energy in a physical system that can be converted to do work, in particular: * * Helmholtz free energy (A=U–TS), the energy that can be converted into work at a constant temperature and volume * * *Work content, a related concept used in chemistry * * Gibbs free energy (G=H–TS), the energy that can be converted into work at a constant temperature and pressure throughout a system * Variational free energy, a construct from information theory that is used in variational Bayesian methods In economics: * Energy from sources that do not require an input which has to be paid for, (usually a sub-set of renewable energy) In pseudoscience: * Free energy device * * a hypothetical perpetual motion device that creates energy, thereby contradicting the laws of thermodynamics In popular culture: *Free energy suppression, a conspiracy theory that advanced energy technologies are being suppressed by governments and/or special interest groups In music: *Free Energy (band), a 5-piece rock band on DFA Records ==See also== *Free-energy relationship - a relation between the reaction rate or equilibrium constants of two series of chemical reactions *Free energy perturbation - a method based on statistical mechanics that is used in computational chemistry for computing free energy differences *Free energy principle - a variational formulation of self-organisation in biological systems, applied in particular to neuroscience *Principle of minimum energy - a thermodynamic formulation based on the second law 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Free energy」の詳細全文を読む スポンサード リンク
