JAMB Physics: Topics to Focus On for 2027
JAMB Physics topics to focus on for 2027, from the syllabus structure: must-master mechanics and electricity, commonly tested areas and lower-weight topics.
ExamPadi Editorial · Updated · 8 min read
Physics at UTME level is a subject of connected ideas. Motion leads to forces, forces lead to work and energy, energy appears in heat and electricity, and waves tie in with light and sound. If you learn the topics in a good order, each one makes the next easier. If you learn them in a random order, the same equations look like unrelated tricks.
This guide arranges the JAMB Physics syllabus for the 2027 cycle into three tiers. We do not claim exact question-frequency percentages, because JAMB does not publish a topic breakdown we can verify. "Commonly tested" here is our editorial judgement of topics that come up often in practice sets or that underpin many others, not an official count. Compare it with the current syllabus and brochure on jamb.gov.ng, which also give the exam format and time allowed.
The map of the syllabus
The ExamPadi subject outline for Physics lists these blocks: mechanics, heat energy, waves and optics, electricity and magnetism, modern physics, atomic and nuclear physics, electromagnetic induction, sound waves, electronics, and vectors and scalars.
| Block | Core ideas |
|---|---|
| Mechanics | Measurement, vectors, motion, forces, work, energy, power, machines |
| Heat | Temperature, expansion, specific heat capacity, latent heat, gas laws |
| Waves and optics | Wave properties, reflection, refraction, lenses, mirrors, sound |
| Electricity and magnetism | Charge, current, circuits, magnetic fields, induction |
| Modern physics | Atomic structure, radioactivity, energy levels, basic electronics |
Tier 1: must-master topics
Measurements, units and vectors
Why it matters: units and vectors support every calculation. Many errors come from mixing units or adding vectors as if they were ordinary numbers.
How to practise: write the unit with every quantity. Practise converting between units, and add two vectors by drawing a triangle or parallelogram. Learn the difference between scalar and vector quantities by listing examples of each.
Motion and Newton's laws
Why it matters: the equations of motion and Newton's laws appear in questions on falling bodies, projectiles, vehicles and machines.
How to practise: learn the standard equations (v = u + at, s = ut + ½at², v² = u² + 2as) and what each variable means. An original example: A car starts from rest and accelerates at 2 m/s² for 5 s. What distance does it cover? Using s = ut + ½at² with u = 0, s = ½ × 2 × 25 = 25 m.
Work, energy and power
Why it matters: the work–energy ideas link mechanics to heat and electricity. Power is also used in electrical questions.
How to practise: learn work = force × distance, kinetic energy = ½mv², potential energy = mgh and power = work ÷ time. Use unit checking: joules for energy, watts for power.
Current electricity
Why it matters: circuits are a large and predictable part of Physics, and the skills are shared with technical subjects.
How to practise: use Ohm's law, resistors in series and parallel, and the idea of electromotive force and internal resistance. Draw every circuit before you calculate.
Tier 2: commonly tested topics
| Topic | Why it matters | How to practise |
|---|---|---|
| Heat and thermal properties | Specific heat capacity, latent heat and expansion appear in short calculations | Learn Q = mcΔθ and Q = ml with examples |
| Gas laws | Boyle's, Charles's and pressure laws | Keep temperature in kelvin and do five examples of each |
| Waves and sound | Wave equation, speed, frequency, wavelength | Use v = fλ and sketch wave diagrams |
| Light: reflection and refraction | Mirror and lens problems, refractive index | Draw ray diagrams in a standard layout |
| Static electricity and fields | Charge, fields, capacitors | Learn definitions and basic relationships |
| Magnetism and electromagnetic induction | Fields, forces on conductors, generators and transformers | Learn the right-hand rule and the transformer equation |
| Radioactivity and the atom | Decay, half-life, nuclear reactions | Practise half-life tables |
An original half-life example: A radioactive sample has a half-life of 4 days. What fraction remains after 12 days? Twelve days is three half-lives, so the fraction is (½)³ = 1/8.
Tier 3: lower-priority topics
These deserve attention once the earlier tiers are strong; the order is ours, not JAMB's.
- Elementary electronics: learn the idea of diodes, transistors and logic basics at the level of your syllabus.
- Simple machines and fluid details: know the main types and the idea of mechanical advantage.
- Specialised atomic models: know the basic structure and the main experiments in outline.
- Alternating current details: learn the basic ideas and the meaning of peak and r.m.s. values.
Study order that works
| Week | Focus |
|---|---|
| 1 | Units, vectors, motion |
| 2 | Forces, Newton's laws, work, energy, power |
| 3 | Heat and gas laws |
| 4 | Waves, sound, light |
| 5 | Electricity and magnetism |
| 6 | Modern physics, electronics, mixed timed sets |
For techniques on calculation and time, read how to pass JAMB Physics and how to solve maths faster. Chemistry shares many calculation habits; see JAMB Chemistry topics to focus on if you are taking both.
How to practise by topic
Do 15 to 20 questions on one topic at a time. For every error, note whether it was a concept slip, a formula slip or an arithmetic slip. Repeat the topic after three days. If an error type keeps coming back, add it to your notes as a rule.
Practise it
ExamPadi has free JAMB Physics practice with a timed CBT mode on Android, iOS, web and Windows. Use it to test each tier before moving on.

Which Physics topics should I learn first?
Start with measurements, vectors, motion and forces. They are the language of the rest of the subject, and the same equations return in energy, electricity and waves.
Is JAMB Physics mostly calculations?
It is a mix of concept questions and short calculations. Learn the formulas with their units, and practise substituting carefully.
How do I remember so many formulas?
Group them by topic, learn what each symbol means, and practise using them in questions. A formula you can derive from a unit check is easier to remember than one you copy.
Do I need a calculator?
Check the current JAMB rules on calculators. Practise by hand so that you are comfortable either way.
