Dynamics (mechanics)

In physics, dynamics or classical dynamics 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.

Applications

Classical dynamics finds many applications:

• Aerodynamics, the study of the motion of air
• Brownian dynamics, the occurrence of Langevin dynamics in the motion of particles in solution
• File dynamics, stochastic motion of particles in a channel
• Flight dynamics, the science of aircraft and spacecraft design
• Molecular dynamics, the study of motion on the molecular level
• Langevin dynamics, a mathematical model for stochastic dynamics
• Orbital dynamics, the study of the motion of rockets and spacecraft
• Stellar dynamics, a description of the collective motion of stars
• Vehicle dynamics, the study of vehicles in motion

Generalizations

Non-classical dynamics include:

• System dynamics, the study of the behavior of complex systems
• Quantum dynamics analogue of classical dynamics in a quantum physics context
• Quantum chromodynamics, a theory of the strong interaction (color force)
• Quantum electrodynamics, a description of how matter and light interact
• Relativistic dynamics, a combination of relativistic and quantum concepts
• Thermodynamics, the study of the relationships between heat and mechanical energy
