Classical Mechanics Foundations

Scope and Purpose of Classical Mechanics

Classical mechanics is a framework for describing how forces affect the motion of macroscopic objects and bulk matter, generally without accounting for quantum effects and, in its non-relativistic form, relativistic effects. It applies to systems ranging from projectiles, machinery, spacecraft, planets, and stars to deformable solids, fluids, and macromolecules. Its central purpose is to use known positions, velocities, masses, and forces to determine how objects move over time, both in the future and the past, within the limits of predictable behavior. The subject includes statics, kinematics, and dynamics, and can be expressed through Newtonian, Lagrangian, or Hamiltonian formulations. Classical mechanics is highly accurate for objects that are not extremely small, massive, or fast, but it becomes an approximation when quantum effects, strong gravitational fields, or speeds near the speed of light are important. Quantum mechanics, special relativity, and general relativity extend or replace it in those regimes.
