- Oscillations and waves Acceleration is proportional to displacement and directed towards the equilibrium position: a = −ω²x.
- Thermal physics and ideal gases Internal energy is the sum of the random kinetic and potential energies of the molecules. Thermodynamic temperature T (K) = θ (°C) + 273.15; absolute zero is 0 K.
- Electric fields and capacitance An electron moving across a uniform field follows a parabolic path, like a projectile.
- Magnetic fields and electromagnetic induction Magnetic forces Force on a current-carrying conductor: F = BIL sin θ (Fleming's left-hand rule).Force on a moving…
- Quantum and nuclear physics Light consists of photons with energy E = hf = hc/λ (h = 6.63 × 10⁻³⁴ J s). Electrons are emitted only if hf exceeds the work function φ: hf = φ + ½mv²max. Intensity changes the number of electrons, not their maximum energy – evidence for the particle nature of light.
