The study of the behavior of physical bodies when subjected to forces or displacements.
The study of the motion of bodies under the influence of forces (Statics, Kinematics, Dynamics).
Alternative formulations of classical mechanics (Lagrangian Mechanics, Hamiltonian Mechanics).
The study of fluids and the forces that act upon them (Hydrostatics, Aerodynamics, Hydrodynamics).
Deals with the analysis of the kinematics and the mechanical behavior of materials modeled as a continuous mass (Solid Mechanics, Rheology).
Relating the microscopic properties of individual atoms and molecules to the macroscopic properties of bulk matter.
The study of the motions of celestial objects, such as planets and stars.
