Goal: Build the main pillars.
Topics:
- Rotational motion
- Gravitation
- Thermodynamics
- Waves & oscillations
- Electromagnetism
Math upgrade:
- Basic trigonometry
- Intro to calculus (optional but helpful)
👉 Outcome: You understand most real-world physics systems.
🟣 Phase 3 — Mathematical Physics
Goal: Speak the language of physics.
Must learn:
- Calculus (derivatives, integrals)
- Vectors
- Differential equations
Used in:
- Maxwell’s Equations
- Motion equations
- Wave equations
👉 Outcome: You stop memorizing and start deriving.
