Introduction to Physics as a School Subject
Physics is the branch of science that studies matter, energy, and how they interact. It explains the laws and principles that govern the physical world, from the motion of objects to electricity, heat, light, and sound.
As a school subject, Physics helps students understand everyday phenomena and lays the foundation for careers in engineering, technology, medicine, and other science-related fields. It develops skills in observation, measurement, calculation, and problem-solving, making it both practical and intellectually stimulating.

How to Pass Physics Exam Questions for SS2 Third Term
Passing your Physics exam questions for SS2 Third term requires a combination of preparation, understanding, and strategy. Here are actionable tips to help you excel:
1. Know the syllabus and exam format
List the topics set for the term and the types of questions that usually appear (objectives, theory, calculations, diagrams, practicals). Focus study time on the set topics — do not waste effort on content outside the syllabus.
2. Understand concepts, don’t just memorise
Physics tests understanding. Learn why formulas work (derivations and assumptions) and what each symbol means. When you understand the idea behind a method you can adapt it to new problems.
3. Learn and organise key formulas
Create a one-page formula sheet for revision (laws of motion, energy, wave relations, heat equations, circular motion, electricity, etc.). Write units with each formula — examiners often mark for correct units.
4. Practice calculations every day
Work through worked examples and past questions. Time yourself occasionally. Learn to set up the physics first (identify knowns and unknowns), then pick the correct formula and solve step-by-step.
5. Master diagrams and practicals
Practice drawing clear, labelled diagrams (ray diagrams, circuit diagrams, pendulum setups). Practical questions often ask for observations and reasons — practise writing concise, correct sentences for those.
6. Build good exam technique
- Read the whole paper carefully before starting.
- Tackle questions you know first, then the harder ones.
- Show working clearly — examiners give marks for method.
- Check units and simple arithmetic; errors here cost marks.
- Manage time: allocate minutes per question and keep an eye on the clock.
7. Improve problem-solving speed
Practice tricks: simplify numbers, keep significant figures sensible, and rearrange formulas before substituting numbers. Use calculators correctly — practice with the same model you will use in the exam.
8. Review mistakes and learn from them
When you get a question wrong, write down exactly why and re-solve it. Make a small “mistake log” of formula slips, unit errors, or reasoning gaps and review it weekly.
9. Prepare for practical and theory sections
Revise common experiments (measurements, plots, errors, conclusions). For theory, practise short, precise answers and definitions. Examiners like neat, well-labelled diagrams and clear terminology.
10. Take care of yourself before the exam
Sleep well the night before, eat a light meal, and arrive early. Stay calm — a clear head works better than frantic last-minute cramming.
Quick checklist for exam day:
- Bring a working calculator, ruler, and spare batteries.
- Bring a clean answer booklet and pens; write legibly.
- Skim the paper first; answer high-value questions carefully.
