Classical dynamics focuses primarily on mechanics, which is a physical theory that describes the motion of physical objects (bullets, mechanical parts, spaceships, celestial objects).
They are deterministic theories that provide conceptual and mathematical tools to determine the past movements and predict the future behaviors of objects, given current conditions/states.
These theories are not able to incorporate chaos, indeterminacy, uncertainty, which as we have seen is the protagonist of the most elementary levels of Physical Reality and plays a non-marginal role even at the most complex levels.
Classical mechanics is historically divided into three branches: Statics, Kinematics and Dynamics. Among the classical theories (alongside Newtonian, Lagrangian and Hamiltonian mechanics) we also include Special and General Relativity, which provide conceptual and mathematical reference frameworks for the study of bodies whose speed is close to the speed of light and for gravity in a context of limitation of the speed of propagation of light.
Classical theories have stringent limits for phenomena involving very small spatial dimensions and microscopic objects (waves and particles and their interactions), very high concentrations (e.g. high mass densities), etc. In these cases, where classical and relativistic theories at best only provide approximations, it is necessary to turn to Quantum Field Theory (QFT) and quantum gravity theories, which are unfortunately still in preliminary states of development.
