Dynamics (from Greek δυναμικός - dynamikos "powerful", from δύναμις - dynamis "power") may refer to:

In Physics

• Dynamics (physics), in physics, dynamics refers to time evolution of physical processes
• Analytical dynamics refers to the motion of bodies as induced by external forces
• Relativistic dynamics may refer to a combination of relativistic and quantum concepts to describe the relationships between the motion and properties of a relativistic system and the forces acting on the system. It may also refer simply to the impact of special relativity upon classical dynamics.¹
• Molecular dynamics, the study of motion on the molecular level
• Gravitational dynamics, the study of the dynamics of systems dominated by gravitational force²
• Thermodynamics, a branch of physics that studies the relationships between heat and mechanical energy using macroscopic variables such as temperature, pressure, and volume
• Fluid dynamics, the study of fluid flow; includes:
  • Aerodynamics, the study of gases in motion
  • Hydrodynamics, the study of liquids in motion
• In quantum physics, dynamics may refer to how forces are quantized, as in quantum electrodynamics or quantum chromodynamics.³

Other

• System dynamics, the study of the behaviour of complex systems
• A Dynamical system in mathematics or complexity.
• Dynamics (music), In music, dynamics refers to the softness or loudness of a sound or note. The term is also applied to the written or printed musical notation used to indicate dynamics.
• Group dynamics, the study of social group processes
• Psychodynamics, 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
• Neurodynamics, an area of research in the brain sciences which places a strong focus upon the spatio-temporal (dynamic) character of neural activity in describing brain function
• Power dynamics, the dynamics of power, used in sociology
• Dynamic programming in computer science and control theory.
• Dynamic program analysis, in computer science is a set of methods for analyzing code that is performed with executing programs built from that software on a real or virtual processor.
• Microsoft Dynamics is a line of business software owned and developed by Microsoft.
• UMass Dynamics is a well-known acapella group based out of UMass Amherst.
