SACE Stage 2 Physics study guide
SACE Stage 2 Physics · Work through your exam, one topic at a time.
SACE Stage 2 Physics is the final-year physics subject within the South Australian Certificate of Education, a senior secondary qualification delivered by the SACE Board of South Australia and also offered internationally through SACE International. It suits students in their final year of schooling who are building a science pathway toward university or employment, and who want a mathematically grounded understanding of how the physical world behaves. The subject is organised into four equally weighted areas: Motion and Relativity, Electricity and Magnetism, Light and Waves, and Atomic and Nuclear Physics. Study therefore moves between mechanics and modern physics, and rewards students who can select the right principle, apply it algebraically, and interpret the result physically rather than memorising isolated formulas. Topics on this exam: Motion and Relativity, Electricity and Magnetism, Light and Waves, and Atomic and Nuclear Physics. The SACE Stage 2 Physics study guide has 4 sections and about 1,361 words.
01Motion and Relativity
Motion in SACE Stage 2 rests on distinguishing scalars (distance, speed, mass) from vectors (displacement, velocity, acceleration). Velocity is the rate of change of displacement, so a change of direction is an acceleration even at constant speed.
358 words, about 2 min02Electricity and Magnetism
Electric fields describe the force per unit positive charge, E = F/q, and around a point charge E = kQ/r². Electric potential is energy per unit charge, and potential difference drives current.
347 words, about 2 min03Light and Waves
Waves transfer energy without transferring matter. Key quantities are wavelength, frequency, period, amplitude and speed, linked by v = fλ.
332 words, about 2 min04Atomic and Nuclear Physics
Atomic models progressed from Thomson's plum-pudding model to Rutherford's nuclear model and Bohr's quantised energy levels. Atoms emit and absorb photons when electrons transition between levels, with photon energy equal to the energy difference: E = hf = ΔE.
