Must know

1Physical quantities describe measurable properties such as length, mass, time, and temperature.
2A physical quantity is written as a number with a unit.
3Name the quantity first, then the SI unit. Distinguish fundamental quantities such as length and mass from derived...
4Speed is a derived quantity because it uses length and time together.

Formula / process

1Always pair the quantity name with the unit and one practical example.
2Physical quantities describe measurable properties such as length, mass, time, and temperature.
3Justify the instrument by saying what it measures well and why.
4Measurement instruments are chosen according to the quantity and required precision.

Exam traps

1Students often memorise units without connecting them to the quantity measured.
2Always pair the quantity name with the unit and one practical example.
3Can you say what the unit is measuring, not just its symbol?
4Students may name the instrument but ignore precision and least count.

Answer frame

Start with the exact keyword or formula before adding explanation.
Use one example, diagram cue, observation, or substitution to support the answer.
For 3 marks: definition, reason, and one supporting point.
For 5 marks: setup, method/process, example, conclusion, and final check.

Exam strategy

Write to the mark pattern

3 focus areas

Practice written answers Chapter test

Likely prompts

1Definition-with-unit questions followed by one reason or example.
2Numerical questions where formula, substitution, and unit carry marks.
3Diagram or process questions: ray paths, circuits, forces, energy flow, or graphs.

Keywords to include

1Physical Quantities and Units
2Meaning
3One-minute summary
4Quantity
5Magnitude
6Unit

Avoid these traps

1Students often memorise units without connecting them to the quantity measured.
2Always pair the quantity name with the unit and one practical example.
3Do not write a bare number as a final physics answer.
4Quantity and unit must stay linked.

Answer frame by marks

3 marks

Define the term, write the unit or formula, then add one relevant example.

5 marks

Draw or state the setup, explain the principle, apply the formula/process, and finish with unit or conclusion.
