Physics is the backbone of Engineering, Medicine, Computer Science, and dozens of other competitive courses in Nigerian universities. If you want to score high in the UTME, understanding the area of concentration for JAMB Physics is not optional – it is essential. JAMB draws questions from specific sections of the Physics syllabus every year, and candidates who study these focus areas strategically consistently outperform those who read without direction.
The JAMB Physics syllabus is structured into five major sections: Mechanics, Thermal Physics, Waves and Optics, Electricity and Magnetism, and Modern Physics. Each section carries a different weight in the exam, and knowing how questions distribute across them is the foundation of effective preparation. This guide breaks down the area of concentration for JAMB Physics so you can study with clarity and purpose.
Whether you are a first-time candidate or retaking the exam, this complete breakdown of the area of concentration for JAMB Physics for the 2026/2027 session provides everything you need – from topic-by-topic analysis to essential formulas, a 14-week study plan, and expert strategies to score 70 and above.
Section 1: Mechanics
Mechanics is the largest and most important section in the area of concentration for JAMB Physics, contributing approximately 30–35% of all exam questions. This section covers how objects move, why they move, and the forces that act on them. If you dominate Mechanics, you are already on track for a strong Physics score.
The critical topics under Mechanics include:
- Measurements and Units: Fundamental and derived quantities, SI units, dimensional analysis, and how to test the homogeneity of equations. JAMB tests this topic in almost every sitting.
- Scalars and Vectors: Differences between scalars and vectors, resolution of vectors into components, resultant of two or more forces, and vector addition using the parallelogram and triangle laws.
- Motion (Linear and Projectile): Equations of motion (v = u + at, s = ut + ½at², v² = u² + 2as), velocity-time graphs, distance-time graphs, projectile motion (range, maximum height, time of flight), and relative motion.
- Newton’s Laws of Motion: First law (inertia), second law (F = ma), third law (action and reaction), and practical applications including connected bodies and motion on inclined planes.
- Work, Energy, and Power: Work done by a force (W = Fd cosθ), kinetic energy, potential energy, conservation of energy, power calculations, and efficiency of machines.
- Equilibrium of Forces: Conditions for equilibrium (translational and rotational), moments and torque, centre of gravity, and problems involving balanced beams and ladders.
- Elasticity – Hooke’s Law: Force-extension relationships, elastic limit, Young’s modulus, and energy stored in a stretched spring.
- Pressure: Pressure in solids, liquids, and gases, atmospheric pressure, hydraulic systems, manometers, and Archimedes’ principle (upthrust and flotation).
Mechanics questions are heavily calculation-based. Memorize the equations of motion and practice applying them to different scenarios – you can expect at least 12–14 questions from this section alone.
Section 2: Thermal Physics (Heat)
Thermal Physics is the second section in the area of concentration for JAMB Physics, contributing about 15–20% of exam questions. This section deals with heat energy, temperature measurement, and the behaviour of gases.
- Gas Laws: Boyle’s law (P₁V₁ = P₂V₂), Charles’ law (V₁/T₁ = V₂/T₂), the general gas equation (P₁V₁/T₁ = P₂V₂/T₂), and the ideal gas equation (PV = nRT). JAMB asks gas law calculations every year.
- Quantity of Heat and Specific Heat Capacity: Q = mcΔθ, method of mixtures, and calculations involving heat gained equals heat lost.
- Change of State and Latent Heat: Specific latent heat of fusion and vaporization (Q = mL), heating and cooling curves, and evaporation versus boiling.
- Heat Transfer: Conduction (metals as good conductors), convection (fluid movement), radiation (emission and absorption), and practical applications like vacuum flasks.
- Thermal Expansion: Linear, area, and volume expansion, coefficients of expansion, and real-life applications (railway tracks, bimetallic strips, expansion joints).
- Kinetic Theory of Matter: Molecular arrangement in solids, liquids, and gases, Brownian motion, and the relationship between temperature and molecular kinetic energy.
Always convert temperature to Kelvin before applying gas law formulas. This is one of the most common errors candidates make in Thermal Physics calculations.
Section 3: Waves and Optics
Waves and Optics form a significant area of concentration for JAMB Physics, accounting for approximately 15–20% of exam questions. This section tests your understanding of wave behaviour, sound properties, and the nature of light.
Waves and Sound
- Properties of Waves: Types of waves (transverse and longitudinal), wave parameters (amplitude, wavelength, frequency, period, velocity), and the wave equation v = fλ.
- Sound Waves: Production, propagation, speed of sound in different media, echoes, reverberation, resonance, and the Doppler effect.
- Superposition of Waves: Interference (constructive and destructive), stationary waves, nodes and antinodes, and overtones in pipes and strings.
Light and Optics
- Reflection of Light: Laws of reflection, plane mirrors (image formation), curved mirrors (concave and convex), mirror formula (1/f = 1/u + 1/v), and magnification.
- Refraction of Light: Snell’s law (n = sin i / sin r), critical angle, total internal reflection, applications (optical fibres, mirages), and refraction through lenses.
- Lenses: Converging and diverging lenses, lens formula, power of a lens, ray diagrams, and image characteristics.
- Dispersion and Electromagnetic Spectrum: Splitting of white light into colours, the electromagnetic spectrum (radio waves to gamma rays), and properties of each region.
Draw ray diagrams for every mirror and lens question. JAMB frequently tests your ability to trace rays and determine the nature, position, and size of images. Practise until ray diagrams become instinctive.
Section 4: Electricity and Magnetism
Electricity and Magnetism is one of the heaviest sections in the area of concentration for JAMB Physics, contributing about 20–25% of exam questions. This section combines theory and calculations, and mastering it can earn you 8–10 marks.
- Electrostatics: Electric charges, Coulomb’s law, electric field intensity, electric potential, and the gold-leaf electroscope.
- Capacitors: Capacitance, parallel plate capacitors, series and parallel combination of capacitors, energy stored in a capacitor (E = ½CV²), and charging/discharging behaviour.
- Current Electricity: Ohm’s law (V = IR), resistors in series and parallel, internal resistance and EMF of cells, Kirchhoff’s laws, and the Wheatstone bridge.
- Electrical Energy and Power: P = IV, P = I²R, P = V²/R, cost of electricity calculations, and household wiring safety (fuses, earthing).
- Magnetic Fields and Forces: Properties of magnets, magnetic field lines, force on a current-carrying conductor in a magnetic field (F = BIL), and the D.C. motor principle.
- Electromagnetic Induction: Faraday’s law, Lenz’s law, the A.C. generator, the transformer (step-up and step-down), and eddy currents.
Circuit problems dominate this section. Practice calculating total resistance in mixed series-parallel circuits, and always double-check your units (especially converting milliamps to amps and kilowatts to watts).
Section 5: Modern Physics
Modern Physics is the final section in the area of concentration for JAMB Physics and contributes about 5–10% of questions. Although it carries fewer questions, the topics are straightforward and offer easy marks to well-prepared candidates.
- Radioactivity: Types of radiation (alpha, beta, gamma), properties of each type, half-life calculations (N = N₀(½)^(t/T)), nuclear reactions, and applications of radioactivity (medical, industrial, carbon dating).
- Photoelectric Effect: Einstein’s photoelectric equation (E = hf – W₀), threshold frequency, work function, stopping potential, and the wave-particle duality of light.
- Atomic Structure: Bohr’s model, energy levels, electron transitions, and emission/absorption spectra.
- Conduction of Electricity Through Gases: Thermionic emission, cathode rays, X-rays, and their applications.
Half-life calculations are the most frequently tested topic in Modern Physics. If you can solve half-life problems confidently, you secure 2–3 marks with minimal effort.

Expert Tips to Score 70+ in JAMB Physics
- Master the formulas first. Physics without formulas is like driving without a steering wheel. Know the 20 essential formulas in this guide and practise applying each one to different question types.
- Understand the concepts behind the formulas. Memorizing F = ma is not enough – you need to understand what each variable represents and when to apply the formula.
- Practice calculations daily. Physics is approximately 70% calculations and 30% theory. Dedicate most of your study time to solving problems rather than just reading.
- Draw diagrams for every question that involves forces, circuits, mirrors, or lenses. Visual representation simplifies complex problems and reduces errors.
- Check units consistently. Converting grams to kilograms, centimetres to metres, or milliamps to amps incorrectly is the number one cause of wrong answers in Physics calculations.
- Use past questions as your primary revision tool. After studying each section, immediately solve 20–30 related past questions to reinforce your understanding.
- Take weekly mock exams. Simulate the CBT environment by solving 40 questions within 50 minutes to build exam stamina and time management skills.
Common Mistakes to Avoid
Even candidates who study the area of concentration for JAMB Physics thoroughly still lose marks to avoidable errors. Watch out for these:
- Unit conversion errors: Failing to convert cm to m, g to kg, or mA to A before applying formulas. Always convert to SI units first.
- Confusing scalars and vectors: Speed is scalar, velocity is vector. Distance is scalar, displacement is vector. JAMB deliberately includes options that test this distinction.
- Wrong formula selection: Using v = u + at when the question provides distance but not time (you should use v² = u² + 2as instead). Read the question carefully to identify which equation fits.
- Ignoring negative signs: In mirror and lens calculations, sign conventions matter. Concave mirrors have positive focal lengths, convex mirrors have negative focal lengths.
- Skipping Modern Physics: Some candidates abandon Modern Physics because it seems complex. Half-life and photoelectric effect questions are predictable and reward basic preparation.
