SQA National 5 Physics: complete guide to the six areas, the question paper and the assignment
A complete guide to SQA National 5 Physics, an SCQF level 5 qualification. Covers the six areas of content (Dynamics, Space, Electricity, Properties of Matter, Waves and Radiation), how the course assessment splits between the question paper and the assignment, the skills of scientific inquiry and uncertainties, and how to study each area for an A.
SQA National 5 Physics is a one-year course at SCQF level 5, building on National 4 Physics and preparing learners for Higher Physics. It is graded A to D from two assessment components: a question paper and an assignment. This page is the index: below is a map of the six areas of content, the assessment structure, and how to study each one.
The six areas of SQA National 5 Physics
The course specification organises the content into six areas. Each is taught alongside the skills of scientific inquiry so that knowledge and practical skill are developed together.
- Dynamics
- Motion and forces: vectors and scalars; speed, velocity and acceleration with velocity-time graphs; Newton's laws and the relationship between force, mass and acceleration; work done, kinetic energy and gravitational potential energy; and projectile motion treated as separate horizontal and vertical components.
- Space
- Our place in the universe: space exploration, including rocket thrust, weight and mass on different bodies, and the benefits and risks of space travel; and cosmology, including the electromagnetic spectrum used to study the universe and the use of spectral lines and redshift as evidence for an expanding universe.
- Electricity
- Charge and circuits: electrical charge carriers and the relationship between charge, current and time; potential difference as energy per unit charge; Ohm's law and resistance in series and parallel; practical electrical and electronic circuits with switches, components and the potential divider; and electrical power and energy.
- Properties of Matter
- Heat, gases and pressure: specific heat capacity and the energy needed for a temperature change; specific latent heat and the energy of a change of state; the gas laws (pressure, volume and temperature) explained by the kinetic model; and pressure as force per unit area.
- Waves
- Wave behaviour and light: wave parameters (frequency, wavelength, period, speed and amplitude) and behaviours such as diffraction; the electromagnetic spectrum and the uses and detectors of each band; and the refraction of light at a boundary.
- Radiation
- The atom and nuclear safety: nuclear radiation including alpha, beta and gamma and their properties; dosimetry, with absorbed dose, equivalent dose and equivalent dose rate; and half-life and its use in dating and in medical and industrial contexts.
Course assessment
The National 5 Physics award is graded A to D and is made up of two components, both set and marked by the SQA.
- Question paper - 135 marks, sat under exam conditions. It has an objective-test (multiple-choice) section worth 25 marks and an extended-answer section worth 110 marks. It assesses both demonstrating and applying knowledge of physics and the application of scientific inquiry skills to data and experiments. A data sheet and a relationships sheet are provided.
- Assignment - 20 marks (scaled into the total). A candidate carries out an experiment with a physics basis, gathers experimental and literature data, and writes a report under controlled conditions covering aim, data handling, a graph, analysis, a conclusion and an evaluation of the procedure.
The two components combine to give the overall award. There is no separate unit assessment in the graded award.
The skills of scientific inquiry
Across both components, the SQA tests the scientific method, not just recall:
- Planning. Identifying the independent, dependent and controlled variables and selecting a valid procedure.
- Selecting and presenting. Reading and drawing tables and line graphs correctly, with labelled axes and units.
- Processing. Calculations such as averages, gradients and percentage uncertainties from repeated readings.
- Analysing and concluding. Drawing a valid conclusion that is supported by the evidence and answers the aim.
- Evaluating. Judging reliability and accuracy, identifying sources of uncertainty, and suggesting improvements.
How to study SQA National 5 Physics
National 5 Physics rewards careful calculation and precise language.
- Work from the key areas. Each mandatory key area in the SQA course specification is a checklist; question-paper items are written from them.
- Drill selecting relationships. The relationships sheet is provided, so the skill is choosing the right one, substituting correctly and quoting the unit. Practise until this is automatic.
- Apply to unfamiliar contexts. Many marks come from interpreting data, graphs and experiments you have never seen before.
- Learn definitions exactly. Marks reward correct named terms, such as the difference between scalars and vectors or between absorbed dose and equivalent dose.
- Practise past papers. Use SQA past papers and marking instructions to learn the question style and the wording markers reward.

The SQA publishes the full National 5 Physics course specification, specimen and past papers, and marking instructions at sqa.org.uk. Always revise from the current specification and SQA past papers, because question style and terminology are board-specific.
