- Buoyancy (Archimedes’ Principle)
- Fluid flow and the continuity equation
- Bernoulli’s Principle
2. Thermodynamics
- Temperature, heat, and internal energy
- First law of thermodynamics and energy conservation
- Heat engines and efficiency (Second law of thermodynamics)
- Adiabatic, isothermal, isobaric, and isochoric processes
3. Electric Force, Field, and Potential
- Electrostatic forces between charges (Coulomb’s Law)
- Electric field intensity and electric potential energy
- Electric field and potential mapping
4. Electric Circuits
- Ohm’s Law and series/parallel circuits
- Capacitor characteristics and charging/discharging behavior
- Basic DC and AC circuit analysis
5. Magnetism and Electromagnetic Induction
- Generation and properties of magnetic fields
- Lorentz force (magnetic force on charged particles)
- Faraday’s law of induction and electromagnetic induction
6. Geometric and Physical Optics, Quantum, Atomic, and Nuclear Physics
- Reflection and refraction (Snell’s Law)
- Imaging principles of lenses and mirrors
- Interference and diffraction of light
- Quantum phenomena (photoelectric effect)
- Atomic models and nuclear physics (nuclear reactions and radioactive decay)
