IB Physics: a pendulum and a spring at the left, a battery-and-bulb circuit in the centre, and a thick wave ribbon with an interference-band screen at the right, covering mechanics, electricity and waves.

Build models around current IB Physics, then strengthen data, papers and investigation skills.

  • Choose and evaluate physical models by scale, system, interaction and assumption
  • Use mathematics and graphs to express physical reasoning with units and uncertainty
  • Match command terms with complete causal explanations across the course themes
  • Align investigation design, data processing and evaluation while preserving student authorship

Course highlights

Choose and evaluate physical models Define scale, system, interaction and assumptions before using mathematical relationships.
Represent the system
Use diagrams, vectors, fields, waves and energy descriptions deliberately.
Compare models
Judge where classical, field, wave or quantum descriptions apply.
State limitations
Explain the consequence of approximation and neglected effects.
 Turn mathematics into physical reasoning Use equations and graphs to express a model, not as detached procedures.
Derive transparently
Keep symbols, vectors, units and assumptions visible.
Analyse data
Use gradients, areas, linearisation and uncertainty correctly.
Interpret results
Check scale, direction, dimensions and physical plausibility.
 Answer command terms with complete causal arguments Connect a principle to the mechanism and then to the predicted observation.
Use precise concepts
Distinguish force, field, potential, energy, phase and probability.
Control depth
Match state, outline, explain, derive and evaluate.
Integrate themes
Transfer common reasoning across mechanics, fields, waves and quantum physics.
 Build a coherent scientific investigation Align research question, method, data processing and evaluation while preserving student authorship.
Design measurable relationships
Choose variables, range, controls, repeats and apparatus.
Process uncertainty
Use graphs, fits and derived quantities with proportionate precision.
Evaluate evidence
Link limitations to effects, improvements and the scope of the conclusion.
