### Frameworks of Classical Newtonian Mechanics
Classical mechanics models the deterministic motion of macroscopic objects under forces:
- **Newton's Laws of Motion:** First Law (Inertia: bodies maintain constant velocity absent net force); Second Law ( = ma$: force equals mass times acceleration); Third Law (Action-Reaction: matched equal and opposite force pairs).
- **Energy, Work and Power:** Work ( = F \cdot d \cos\theta$) transfers energy, measured in Joules. Kinetic Energy ( = \frac{1}{2}mv^2$) quadruples when speed doubles. Gravitational Potential Energy near Earth is = mgh$. Power ( = W/t$) is measured in Watts ($1\text{ hp} \approx 746\text{ W}$).
- **Conservation Laws:** In an isolated system, total mechanical energy ( + PE$) and total linear momentum ( = mv$) are strictly conserved. Elastic collisions conserve kinetic energy; inelastic collisions dissipate kinetic energy into heat/sound.
- **Gravitation and Fluids:** Universal gravitation follows an inverse-square law ( = G\frac{m_1 m_2}{r^2}$). Archimedes\' principle explains buoyancy, Pascal\'s principle governs hydraulics, and Bernoulli\'s equation relates fluid velocity to static pressure.
