Magnetism:
Magnetic fields, current loops and magnetic materials. The laws of Biot-Savart and Ampere applied to electric currents in wires and solenoids. Electromagnetic induction (Faraday's Law and Lenz' Law), self inductance and magnetic energy density.
Current Electricity:
dc current, electrical resistivity of conducting materials and batteries. ac currents in resistors, capacitors and inductors.
Oscillations:
Simple Harmonic Motion (period, amplitude, velocity, acceleration and energy) and its application in mechanical pendulums for measuring g and LC circuits for frequency generators. Damped and forced oscillations. Resonance in mechanical (suspension systems) and electrical systems (LCR circuits).
Heat and Temperature:
Oscillations in molecules, energy, temperature, thermal expansion and thermal conductivity. Thermometers and the ideal gas temperature scale. Thermal equilibrium versus heat transfer and the Zeroth law of Thermodynamics. Thermal materials.
Wave Motion:
Travelling waves and the wave equation (wavelength, frequency, phase velocity). Superposition of waves, interference and standing waves (e.g. in water). Dispersion, wave packets and group velocity. Doppler Effect in sound waves and light.
