In physics, dynamics or classical dynamics [1] [2] [3] is the study of forces and their effect on motion. It is a branch of classical mechanics , along with statics and kinematics . The fundamental principle of dynamics is linked to Newton's second law .
In music, the dynamics of a piece are the variation in loudness between notes or phrases.Dynamics are indicated by specific musical notation, often in some detail.However, dynamics markings require interpretation by the performer depending on the musical context: a specific marking may correspond to a different volume between pieces or even sections of one piece.
Dynamics (from Greek δυναμικός dynamikos "powerful", from δύναμις dynamis "power") or dynamic may refer to: Physics and engineering.
Secondly, the word dynamics ("science of force [or power]") [22] can be traced back to the root δύναμις dynamis, meaning "power". [23] [24] In 1849, the adjective thermo-dynamic is used by William Thomson. [25] [26] In 1854, the noun thermo-dynamics is used by Thomson and William Rankine to represent the science of generalized heat ...
There are two main descriptions of motion: dynamics and kinematics.Dynamics is general, since the momenta, forces and energy of the particles are taken into account. In this instance, sometimes the term dynamics refers to the differential equations that the system satisfies (e.g., Newton's second law or Euler–Lagrange equations), and sometimes to the solutions to those equations.
System dynamics is an approach to understanding the behaviour of systems over time. It deals with internal feedback loops and time delays that affect the behaviour and state of the entire system. [3] What makes using system dynamics different from other approaches to studying systems is the language used to describe feedback loops with stocks ...
In mathematics, specifically in the study of dynamical systems, an orbit is a collection of points related by the evolution function of the dynamical system. It can be understood as the subset of phase space covered by the trajectory of the dynamical system under a particular set of initial conditions, as the system evolves.
The concept of a dynamical system has its origins in Newtonian mechanics.There, as in other natural sciences and engineering disciplines, the evolution rule of dynamical systems is an implicit relation that gives the state of the system for only a short time into the future.
