Build connected physics models, then strengthen calculations, graphs and practical responses.

  • Define the physical system, interactions and assumptions before choosing equations
  • Connect equations and graph features to quantities, units and physical meaning
  • Build written explanations as a causal chain from principle to observed effect
  • Treat practical work as one evidence process from design and measurement to evaluation

课程重点

Choose the physical model before selecting an equation Students often know formulae but cannot identify the system, interaction or assumption represented by them.
Define the system
Mark objects, boundaries, directions, interactions and neglected effects.
Use a decisive diagram
Construct a force, circuit, ray, field or energy diagram before calculation.
Test the model
Check whether conservation laws, field approximations or material assumptions apply.
 Connect equations, graphs and physical meaning Mathematical steps should describe a physical relationship rather than becoming detached manipulation.
Read graphs physically
Interpret gradient, area, intercept, curvature and uncertainty in context.
Control quantities
Track vectors, signs, units, significant figures and proportional relationships.
Evaluate the result
Use order of magnitude, limiting cases and dimensions to detect impossible answers.
 Write causal explanations that earn marks Replace keyword lists with a clear chain from law or mechanism to the observed effect.
Name the principle
Identify the relevant law, field interaction, wave behaviour or particle process.
State the change
Explain what changes, in which direction and under what condition.
Complete the consequence
Connect the mechanism to the measured or observed outcome.
 Treat practical questions as evidence problems Integrate method, measurement, data processing, uncertainty and evaluation into one argument.
Design for the quantity
Choose variables, range, repeats and apparatus from the relationship being tested.
Process transparently
Show how raw readings become graphs, gradients or derived quantities.
Evaluate specifically
Link each limitation to its effect and a practical improvement.
