A strong Physics answer responds to the command word, shows the required method and uses precise quantities. The examiner can only award what is visible on the page, so good technique makes understanding easier to recognise.
Begin with the command word
Underline the word that controls the answer:
- State: give the required fact briefly.
- Describe: say what happens or what the data shows.
- Explain: connect a cause to an effect using Physics.
- Calculate: show the equation, substitution and final unit.
- Determine: obtain the value from data, a graph or more than one step.
- Suggest: apply Physics to the unfamiliar situation.
Do not write a long explanation for a one-mark state question. Do not answer an explain question with a restatement of the result.
Make calculations visible
Use a consistent layout:
- Standard equation.
- Unit conversion.
- Substitution.
- Rearrangement or arithmetic.
- Answer with unit and sensible significant figures.
This allows method credit to remain visible even when the final number is wrong.
Build explanations as linked statements
A useful explanation names the changing quantity, the physical mechanism and the result. For gas pressure, for example, describe the change in particle motion, the change in collisions and the resulting force per unit area.
Avoid vague words such as “more energy,” “heat rises” or “it becomes stronger” when the question needs kinetic energy, density, current, field strength or another precise quantity.
Use data rather than adjectives
When comparing results, quote values or describe the trend. “The value doubles when the length doubles” is stronger than “the value increases a lot.” On a graph, refer to the gradient, intercept or shape rather than saying the line “looks right.”
Mark your own work carefully
Use the official mark scheme for official papers. For original questions on this site, use the stated marking points as a learning guide, not as an official Cambridge scheme. Record the reason for each lost mark and retry the question later without looking at the solution.
The command-word, calculation and graph guides provide focused practice for each answer type.
