in physics, a branch of mechanics; see dynamics (mechanics). More generally an adjective applying to a theory or model that describes the effects of forces on a system. A system in which all time evolution has stopped is said to be in steady-state.
A Superconductor demonstrating the Meissner Effect. ... Mechanics refers to: a craft relating to machinery (from the Latin mechanicus, from the Greek mechanikos, meaning one skilled in machines), or a range of disciplines in science and engineering. ... In physics, dynamics is the branch of classical mechanics that is concerned with the effects of forces on the motion of objects. ... Thermodynamics (from the Greek thermos meaning heat and dynamis meaning power) is a branch of physics that studies the effects of changes in temperature, pressure, and volume on physical systems at the macroscopic scale by analyzing the collective motion of their particles using statistics. ... In psychology, psychodynamics is the study of the interrelationship of various parts of the mind, personality, or psyche as they relate to mental, emotional, or motivational forces especially at the subconscious level. ... This article needs to be wikified. ... Music is an art, entertainment, or other human activity which involves structured and audible sound, though definitions vary. ... In music, dynamics refers to the volume or loudness of the sound or note, in particular to the range from soft (quiet) to loud. ...

Fluid dynamics is the study of fluids (liquids and gases) in motion, and the effect of the fluid motion on fluid boundaries, such as solid containers or other fluids.
Fluid dynamics is a branch of fluid mechanics, and has a number of subdisciplines, including aerodynamics (the study of gases in motion) and hydrodynamics (liquids in motion).
The central equations for fluid dynamics are the Navier-Stokes equations, which are non-linear differential equations that describe the flow of a fluid whose stress depends linearly on velocity and on pressure.
One particularly noteworthy use of this dynamic is in Joseph Haydn's Surprise Symphony.
They tend to be used for dynamic changes over a relatively short period of time, while cresc and dim are generally used for dynamic changes over a longer range.
The Renaissance composer Giovanni Gabrieli was one of the first to indicate dynamics in music notation, but dynamics were used sparingly by composers until the late 18th century.
