IB Physics SL study plan

IB Physics SL · Give each week a clear focus.

8 weeks · About 7 hours per week

Week 1

Mechanics

  • Derive and apply the three SUVAT equations to solve constant-acceleration problems without looking at notes

  • Draw free-body diagrams for at least six situations involving friction, tension, and inclined planes, then write the net-force equation for each

  • Distinguish clearly between mass and weight and compute apparent weight in an accelerating lift

  • State Newton's three laws in your own words and match each to a worked example

Your checkpoint

A one-page formula sheet for kinematics and dynamics plus 15 solved problems with free-body diagrams, self-marked against the mark scheme

Week 2

Mechanics

  • Apply conservation of momentum to elastic and inelastic collisions and to explosion problems

  • Calculate work, kinetic energy, gravitational potential energy, and power in multi-step problems

  • Interpret and sketch force–displacement and force–time graphs, extracting work and impulse as areas

  • Solve pulley and connected-mass problems using a single system equation

Your checkpoint

A timed 45-minute Mechanics mini-paper (Paper 1 style multiple choice plus two structured questions) scored and error-logged

Week 3

Electricity and Magnetism

  • Draw circuit diagrams and apply Kirchhoff's laws to two-loop circuits

  • Calculate equivalent resistance for series, parallel, and mixed networks

  • Use Ohm's law and the power equations to find current, voltage, and dissipated power in each resistor

  • Describe the potential divider and explain how a thermistor or LDR changes output voltage with temperature or light

  • State the difference between emf and terminal potential difference and calculate internal resistance from a graph

Your checkpoint

A worked solution set of 12 circuit problems including two potential-divider design questions, each with a labelled diagram

Week 4

Electricity and Magnetism & Circular Motion and Gravitation

  • Apply F = BIL sinθ and F = qvB sinθ to determine magnitude and direction of magnetic force

  • Explain electromagnetic induction qualitatively and apply Faraday's and Lenz's laws to changing flux

  • Derive and use centripetal acceleration and force for horizontal circles, vertical circles, and banked tracks

  • Apply Newton's law of gravitation and Kepler's third law to satellite and orbital problems

Your checkpoint

A mid-plan mock covering Mechanics, Electricity and Magnetism, and Circular Motion (60 minutes), scored with a topic-by-topic error table

Week 5

Waves

  • Describe and apply the principle of superposition to two-source interference and draw the resulting pattern

  • Use the double-slit equation and the diffraction grating equation to calculate wavelength, slit spacing, and order

  • Explain single-slit diffraction, polarization, and the conditions for observable interference

  • Distinguish transverse from longitudinal waves and relate intensity to amplitude

  • Apply the Doppler effect equations to moving sources and observers

Your checkpoint

A diagram-rich summary sheet of all wave phenomena with the governing equation and one worked example each

Week 6

Atomic, Nuclear and Particle Physics

  • Describe the photoelectric effect and use the Einstein photoelectric equation to find work function and stopping potential

  • Interpret atomic energy-level diagrams and calculate photon wavelength from energy differences

  • Balance nuclear decay equations and apply the half-life relationship to activity and count-rate problems

  • Classify particles as fermions or bosons and list the quark composition of protons, neutrons, and mesons

  • State the conservation laws used in particle interactions and check them in given reactions

Your checkpoint

A 20-question self-written quiz on atomic, nuclear, and particle physics with an answer key and short justifications

Week 7

Measurements and Uncertainties & Thermal Physics

  • Calculate absolute, fractional, and percentage uncertainty and combine uncertainties in sums, products, and powers

  • Determine uncertainty from a graph, including gradient and intercept with error bars

  • Distinguish random from systematic error and describe how to reduce each

  • Apply the ideal gas equation and the kinetic model to relate pressure, volume, and temperature

  • Use specific heat capacity and latent heat in calorimetry and phase-change problems

Your checkpoint

A practical-analysis write-up of one experiment you can actually perform at home, with a data table, uncertainty budget, and graphed result with error bars

Week 8

Energy Production & Measurements and Uncertainties

  • Compare energy sources by specific energy, renewability, and environmental impact

  • Describe the basic operation of a photovoltaic cell and a fossil-fuel power station with Sankey diagrams

  • Calculate efficiency from Sankey diagrams and energy-input data

  • Complete two full timed Paper 1 and Paper 2 sessions under exam conditions

  • Review the error log and re-solve every previously missed question type

Your checkpoint

Two completed full-length practice papers with scores, timing per section, and a final one-page 'weak spots to revise on exam morning' list

Milestones

Week 4: Score at least 65% on the combined mock and identify no more than three recurring error categories in the error table

Week 6: Answer 18 of 20 self-written atomic, nuclear, and particle questions correctly and state the quark composition of proton and neutron from memory

Week 8: Score at least 75% on both full practice papers within the official time allowance, with uncertainty questions attempted rather than skipped
