NCEA Level 2 Physics study plan

NCEA Level 2 Physics · Give each week a clear focus.

8 weeks · About 6 hours per week

Week 1

Mechanics

  • Convert between SI units and solve constant-acceleration problems in one and two dimensions using the kinematic equations, including horizontally launched projectiles.

  • Draw fully labelled free-body diagrams and resolve forces into perpendicular components for objects on inclines and for masses connected over pulleys.

  • Apply Newton's second law to calculate net force, mass or acceleration in situations involving friction, thrust and weight, and distinguish clearly between mass and weight.

  • State and apply the conditions for equilibrium, including moments about a pivot for a balanced beam.

Your checkpoint

A timed 45-minute set of 12 mixed kinematics and force questions marked against the supplied schedule, scoring at least 80%, with every incorrect item rewritten correctly in a dated error log.

Week 2

Mechanics

  • Apply conservation of momentum to one-dimensional collisions and explosions, and classify each as elastic or inelastic using kinetic energy before and after.

  • Calculate work done, power output and efficiency for lifted, pushed and falling objects, including cases where friction dissipates energy.

  • Analyse vertical and horizontal circular motion using v = 2πr/T, a = v²/r and the resultant centripetal force, identifying which real force supplies it.

  • Explain, in written Merit and Excellence style, why energy or momentum is conserved in a described situation and where the energy is transferred.

Your checkpoint

One full Mechanics (AS91171) past-paper section completed in 60 minutes under exam conditions, self-marked against an Achievement Standard schedule to at least 70%, with all 'explain' questions attempted in full sentences.

Week 3

Electricity and electromagnetism

  • Calculate equivalent resistance for series, parallel and mixed resistor networks and predict how current and voltage split across each branch.

  • Apply Kirchhoff's laws to multi-loop circuits, justifying each step with conservation of charge and conservation of energy.

  • Calculate terminal voltage and internal resistance for a real cell, and interpret the gradient and intercept of a V against I graph.

  • Compare the V–I characteristics of a resistor, a filament lamp and a diode, and explain each shape in terms of resistance change.

Your checkpoint

Three circuits (series, parallel, mixed with internal resistance) built in a circuit simulator or on a breadboard, with a prediction-then-measurement table for current and voltage at each component and a written explanation for any reading more than 10% from prediction.

Week 4

Electricity and electromagnetism

  • Sketch magnetic field patterns around a bar magnet, a straight current-carrying wire and a solenoid, and determine force direction with the right-hand rules.

  • Calculate the force on a current-carrying conductor using F = BIL and on a moving charge using F = Bqv, including situations where the field is not perpendicular to the current.

  • Explain electromagnetic induction in terms of changing magnetic flux, and use Lenz's law to justify the direction of the induced current.

  • Describe how a simple DC motor and a simple AC generator work, naming the parts and the energy conversions at each stage.

Your checkpoint

A 60-minute combined mock covering the Mechanics and Electricity/Electromagnetism standards, scored against the schedules at 70% or better, with each lost mark tagged as content gap, calculation slip or misread question.

Week 5

Waves

  • Calculate wave speed, frequency, period and wavelength using v = fλ, including cases where a wave crosses into a new medium and frequency stays fixed.

  • Describe and sketch reflection, refraction and diffraction, and explain diffraction in terms of wavelength compared with gap or obstacle size.

  • Apply Snell's law, refractive index and the critical angle formula to trace light through boundaries, and identify when total internal reflection occurs.

  • Analyse standing waves on strings and in open and closed pipes, identifying nodes, antinodes and the harmonic series.

Your checkpoint

A one-page wave summary rebuilt entirely from memory (all formulas plus three labelled diagrams), followed by a 15-question wave set scored at 80% or above.

Week 6

Waves & Atomic and nuclear physics

  • Construct accurate ray diagrams for convex and concave lenses and mirrors, and state whether each image is real or virtual, upright or inverted, enlarged or diminished.

  • Calculate image position and magnification using 1/f = 1/do + 1/di and m = di/do, then check each answer against the ray diagram.

  • Describe the photoelectric effect and calculate photon energy and maximum electron kinetic energy using E = hf and E = hf − W.

  • Relate line emission and absorption spectra to electron energy levels, and explain why each element produces a unique set of lines.

Your checkpoint

Ten hand-drawn ray diagrams plus ten photoelectric calculations submitted together, each diagram matched to its calculated image position, with every mismatch explained in one written sentence.

Week 7

Atomic and nuclear physics

  • Write balanced nuclear equations for alpha, beta-minus and gamma decay, and verify conservation of mass number and atomic number in each.

  • Solve half-life problems by both calculation and graphical methods, including finding the half-life from experimental activity data.

  • Explain mass defect and binding energy using E = mc², and compare the binding energy per nucleon of light, medium and heavy nuclei.

  • Compare fission and fusion in terms of energy released per event, conditions required, and one real application of each.

Your checkpoint

A 20-question nuclear set (decay equations, half-life, binding energy) scored at 85% or above, plus a hand-plotted decay curve from supplied activity data with the half-life read off and labelled on the graph.

Week 8

Mechanics & Electricity and electromagnetism & Waves & Atomic and nuclear physics

  • Re-attempt every unresolved item in the error log until each is solved correctly without notes.

  • Sit one full-length mock spanning all four Achievement Standards under strict timing, and mark it against all four schedules.

  • Rebuild the official formulae and definitions sheet from memory, then compare and relearn every gap found.

  • Name the five error patterns that cost the most marks across the eight weeks and write the specific checking habit that prevents each one.

Your checkpoint

A completed full-length mock scored at 80% or above overall, plus a one-page error-pattern sheet listing five named patterns, the domain each affects, and the fix to apply in the exam.

Milestones

Week 2: Mechanics past-paper section completed in 60 minutes and self-marked at 70% or higher, with an error log showing at least five categorised errors and their corrections.

Week 4: Combined Mechanics plus Electricity/Electromagnetism mock scored at 70% or higher, with every lost mark tagged by cause and the highest-frequency cause identified.

Week 6: Waves and Atomic checkpoint: wave question set at 80% or above and all ten ray diagrams verified against calculated image positions.

Week 8: Full-length four-standard mock scored at 80% or above, formula sheet rebuilt from memory with gaps closed, and five named error patterns each paired with a prevention habit.
