About Grade 12 Physical Sciences
Grade 12 Physical Sciences is written as two full papers. Paper 1 is Physics: momentum, projectiles, work energy and power, the Doppler effect, electrostatics, circuits, electrodynamics and optical phenomena. Paper 2 is Chemistry: organic molecules, reaction rate, equilibrium, acids and bases, electrochemistry and the fertiliser industry. Each is typically 150 marks over three hours.
The trap in this subject is memorising formulae you have never understood. You can recite that momentum is conserved and still lose every mark on the collision question because you drew the direction wrong.
The Grade 10, 11 & 12 Physics App carries every DBE past paper and memorandum for both papers, and attaches an interactive simulation to the question types learners lose the most marks on. Change the angle, change the resistance, change the mass, and watch what the examiner is actually asking about.
How the Grade 12 Physical Sciences exam is structured
The typical CAPS end-of-year allocation. Internal and provincial papers can differ — always check your own exam timetable and guideline.

- Momentum and impulse
- Vertical projectile motion in one dimension
- Work, energy and power
- Doppler effect
- Electrostatics
- Electric circuits
- Electrodynamics
- Optical phenomena and the photoelectric effect
- Emission and absorption spectra
Paper 2 — Chemistry
150 marks · 3 hours
- Organic molecules — structure, naming and reactions
- Rate and extent of reaction
- Chemical equilibrium
- Acids and bases
- Electrochemical reactions
- The chemical industry — fertilisers
Grade 12 Physical Sciences topics, term by term
The CAPS content for the year, in the order most schools teach it. Every past paper in the app is tagged to these topics, so you can practise the section you are actually busy with instead of working through a whole paper for four relevant questions.
Term 1
- Momentum and impulse
- Vertical projectile motion
- Organic molecules — structure and naming
- Organic reactions
Term 2
- Work, energy and power
- Doppler effect
- Rate and extent of reaction
- Chemical equilibrium
- Mid-year examinations
Term 3
- Electrostatics
- Electric circuits
- Electrodynamics
- Acids and bases
- Electrochemical reactions
- Trial examinations
Term 4
- Optical phenomena and material properties
- Emission and absorption spectra
- The chemical industry — fertilisers
- NSC final examinations
The app
Where to get the papers
Every physical science grade 12 past paper and memo in one place — and Grade 10 and 11 get the same treatment. Mechanics, electricity, chemical change, vectors and waves, sorted from Term 1 to Term 4 with nothing missing. And every question comes with a physics simulation, so you see the concept move instead of memorising it blind.

How to study with Grade 12 Physical Sciences past papers
Downloading papers is not studying. This is the loop that actually moves a mark.
- 01
Pick a paper you have not seen
Choose a full past paper from a year you have not worked through. Recent papers matter most, but older ones repeat the same question types, so do not skip them.
- 02
Write it under exam conditions
Full time limit, no notes, no phone in reach. A paper you did with the memo open teaches you nothing about what you actually know.
- 03
Mark yourself against the memo
Use the official marking guideline and mark strictly. Method marks matter — mark them the way an examiner would, not the way you wish they would.
- 04
Work through every mistake
For each lost mark, find out why you lost it. Ask the AI tutor in the app to work the question out step by step until you can redo it from a blank page.
- 05
Repeat the question type, not the paper
Find three more questions on the same topic from other years and do those. Papers repeat their patterns — that is the entire reason past papers work.
Where Grade 12 Physical Sciences marks are actually lost
Draw the free-body diagram before you write anything
Almost every mechanics question in Paper 1 is winnable if the forces are drawn correctly and lost if they are not. Examiners award marks for the diagram itself — draw it even when it is not asked for.
Organic chemistry is the most predictable section in Paper 2
Naming, isomers, functional groups and the standard reaction types come up in a recognisable pattern every year. It is the highest return-per-hour section in the entire subject.
Definitions are free marks and most learners drop them
The DBE marks definitions strictly against the exam guidelines wording. Learn them verbatim — Newton's laws, the principle of conservation of momentum, Le Chatelier's principle — and you collect marks before you solve anything.
Grade 12 Physical Sciences past papers — FAQs
The Grade 10, 11 & 12 Physics App has every DBE NSC past paper and marking guideline for Paper 1 and Paper 2, free on Android and iOS, all available offline.
Paper 1 is Physics — mechanics, waves, electricity, electrodynamics and optical phenomena. Paper 2 is Chemistry — organic molecules, reaction rate, equilibrium, acids and bases, electrochemistry and the chemical industry. Each is typically 150 marks over 3 hours.
The papers are provided as the DBE issues them, together with their official marking guidelines, so the accompanying information sheets come with them.
Interactive models built into the app. Instead of only reading about projectile motion or a circuit, you change the variables yourself and watch the outcome, which makes the underlying concept much harder to forget.
Yes. All three grades live in the same app at no cost.
