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 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
