OSAT Physics (OK114) study plan

OSAT Physics (OK114) · Give each week a clear focus.

8 weeks · About 7 hours per week

Week 1

Mechanics and Motion

  • Build a one-page formula sheet for kinematics (constant-acceleration equations, projectile decomposition, relative velocity) and derive each equation from definitions of position and velocity

  • Solve 25 projectile and free-fall problems under timed conditions, including cases with nonzero launch height and angled launches

  • Draw free-body diagrams for 10 systems (incline, pulley, elevator, banked curve) and write Newton's second law for each axis

  • Diagnose and correct three common sign-convention and component-resolution errors you make in practice sets

Your checkpoint

A worked problem portfolio of 25 mechanics problems with free-body diagrams, scored against an answer key, plus a photo of your annotated formula sheet

Week 2

Mechanics and Motion & Energy, Work, and Momentum

  • Derive and apply the work-energy theorem to incline, spring, and friction problems, distinguishing conservative from nonconservative work

  • Solve 15 conservation-of-energy problems involving pendulums, loops, and spring launches, stating the reference level explicitly each time

  • Apply conservation of momentum to 1D and 2D collisions, classifying elastic, inelastic, and perfectly inelastic cases

  • Compute center-of-mass positions and rotational analogs (torque, moment of inertia, angular momentum) for at least 8 standard geometries

Your checkpoint

A timed 20-question quiz on energy and momentum (self-made from textbook end-of-chapter items) with a written error log identifying each mistake's cause

Week 3

Electricity and Magnetism

  • State Coulomb's law and Gauss's law and use each to find the field of point charges, lines, sheets, and spheres

  • Solve 20 circuit problems using series/parallel reduction, Kirchhoff's rules, and RC charging/discharging relations

  • Apply the right-hand rule to compute magnetic force on moving charges and current-carrying wires, and find fields from straight wires, loops, and solenoids

  • Use Faraday's and Lenz's laws to predict induced current direction and magnitude in 8 changing-flux scenarios

Your checkpoint

A labeled concept map linking charge, field, potential, current, magnetic field, and induction, accompanied by 20 solved circuit and induction problems

Week 4

Waves, Sound, and Optics

  • Derive the wave equation relationships among speed, frequency, wavelength, and period, and apply them to string and pipe boundary conditions

  • Solve 15 problems on standing waves, beats, Doppler shift, and resonance in open and closed tubes

  • Trace ray diagrams for mirrors and thin lenses and compute image position, magnification, and nature using the lens/mirror equation

  • Solve 10 problems on Snell's law, total internal reflection, and thin-film interference

Your checkpoint

A mid-point practice test covering mechanics, energy/momentum, electricity/magnetism, and waves (40 questions, 60 minutes) with a scored report and a prioritized list of your three weakest subtopics

Week 5

Thermodynamics and Kinetic Theory

  • State the first and second laws of thermodynamics and apply them to isothermal, adiabatic, isobaric, and isochoric processes

  • Compute efficiency and coefficient of performance for heat engines and refrigerators, and explain why no engine reaches 100 percent

  • Relate temperature to average kinetic energy and root-mean-square speed, and use the ideal gas law in molecular form

  • Solve 15 calorimetry and phase-change problems, including latent heat and mixed-substance equilibrium

Your checkpoint

A one-page summary table of the four thermodynamic processes (work, heat, internal energy change, and path) plus 15 solved kinetic-theory and calorimetry problems

Week 6

Modern Physics and Atomic/Nuclear Physics

  • Apply the photoelectric equation to compute stopping potential, threshold frequency, and maximum kinetic energy

  • Compute photon energy, de Broglie wavelength, and energy-level transitions for hydrogen using the Rydberg relation

  • Balance nuclear equations for alpha, beta, and gamma decay and compute mass defect and binding energy

  • Differentiate fission, fusion, and radioactive half-life calculations with 10 applied problems

Your checkpoint

A 12-question modern physics quiz with full solutions, plus a decay-chain diagram you draw and annotate yourself

Week 7

Foundations of Scientific Inquiry and Physics & Laboratory Safety, Measurement, and Data Analysis

  • Design a controlled experiment for a given physics question, identifying independent, dependent, and controlled variables and stating a testable hypothesis

  • Evaluate measurement uncertainty: report results to correct significant figures and propagate uncertainty through a simple calculation

  • Interpret a supplied data table and graph (slope, intercept, linearization) and draw a defensible conclusion from it

  • List laboratory safety practices for electrical, laser, heat, and radiation equipment and identify violations in 5 written scenarios

Your checkpoint

A complete written lab report for one home-safe experiment (e.g., pendulum period vs. length) including hypothesis, data table, uncertainty treatment, linearized graph, and conclusion

Week 8

Mechanics and Motion & Energy, Work, and Momentum & Thermodynamics and Kinetic Theory & Waves, Sound, and Optics & Electricity and Magnetism & Modern Physics and Atomic/Nuclear Physics

  • Take two full-length timed practice exams under test-day conditions and record raw scores by domain

  • Re-teach your five lowest-scoring subtopics by rewriting their core formulas and solving 5 fresh problems each

  • Build a final one-page master formula sheet organized by domain and verify every entry by derivation or unit check

  • Rehearse pacing: complete each section with at least 10 percent of time remaining for review

Your checkpoint
