Classical mechanics relies on two primary mathematical frameworks: Newtonian mechanics and Lagrangian mechanics. While Newton's laws focus on vector quantities like forces and acceleration, Lagrangian mechanics utilizes scalar quantities—kinetic and potential energy. This energy-based approach simplifies complex systems by eliminating constraint forces and allowing the use of generalized coordinates.
