Physics is the last and shortest section of CEnT-S: only 5 questions in 10 minutes. Questions test basic relations — proportionality, units and graph reading — rather than long numerical solutions.
Because it is only 5 points, study physics efficiently: mechanics alone accounts for most of the questions, and dimensional analysis/proportional reasoning unlocks the rest.

*Question counts per topic in 6 CEnT-S past exams from our question bank; each exam has the full 5 Physics questions. Exams are numbered, not dated. These figures are derived from the past-exam question samples that have reached us; the samples may be incomplete or contain errors, and the topic mix can change from one exam session to the next. Treat them as a guide to priorities, not a prediction of your exam.
Ideas clave
- Mechanics dominates: free fall, motion graphs, Newton's laws and energy conservation.
- Units & proportionality: ‘by what percentage does it change?’ and dimensional analysis.
- Electricity, thermodynamics and waves get one question at most — learn the core relations only.
- 10 minutes for 5 questions: no time for long algebra, look for the ratio.
Dificultad de los temas y reparto de estudio recomendado
No todos los temas exigen el mismo tiempo. Algunos requieren mucha práctica resolviendo problemas; otros dependen de recordar con precisión conceptos concretos:

Un repaso tema por tema de la sección de Physics del official CISIA CEnT-S syllabus:
Physical Quantities & Measurement Fácil
- SI units, prefixes and scientific notation.
- Vectors and their components.
- Functional models: proportional, linear, quadratic, inverse-square, exponential.
Cómo aparece en CEnT-S: Dimensional analysis (‘what are the units of Q?’) and percentage change under a power law.
Kinematics Medio
- Position, displacement, velocity, acceleration.
- Uniform and uniformly accelerated motion; free fall.
- Uniform circular motion; Galilean relativity.
Cómo aparece en CEnT-S: Reading v–t graphs and vertical-throw problems with g = 10 m/s².
Dynamics, Energy & Work Medio
- Inertia and Newton's laws.
- Work, kinetic energy and the work–energy theorem.
- Gravitational potential energy and mechanical energy conservation.
Cómo aparece en CEnT-S: Energy conservation shortcuts instead of kinematics; forces on inclined planes and levers.
Fluids & Thermodynamics Medio
- Density and pressure; Pascal, Stevin and Archimedes.
- Ideal gas state variables and temperature scales.
- First and second law of thermodynamics.
Cómo aparece en CEnT-S: Celsius ↔ Kelvin conversions, buoyancy and hydrostatic pressure.
Electromagnetism & Waves Medio
- Coulomb's law, electric field, conductors and insulators.
- Ohm's law, resistance (R = ρL/A), power and energy (kWh).
- Wave properties, Doppler effect and the electromagnetic spectrum.
Cómo aparece en CEnT-S: Energy-bill style questions (kW × h) and how resistance scales with wire length and diameter.

Los 5 errores más comunes en Physics de CEnT-S
Errores conceptuales y tácticos recurrentes que les cuestan puntos decisivos a los estudiantes:
Linear thinking
Intensity, gravity and Coulomb force go as 1/r²; kinetic energy as v². Check the exponent before computing a percentage.
Power vs energy
kW is power, kWh is energy. Options with the wrong unit can be eliminated instantly.
Sign conventions
In vertical motion choose a positive direction and keep it; mixing signs gives the planted wrong heights.
Celsius vs Kelvin
Absolute temperature in gas laws and thermodynamics must be in kelvin.
Spending too long
10 minutes for 5 questions: if a problem needs more than 3 lines, look for a ratio or energy shortcut.

Diagnostic & Foundations
Take a timed diagnostic; rebuild the Foundation topics marked ‘Easy’ and note every error type.
Core Topics
Work through the ‘Medium’ and ‘Hard’ topics in the order of the frequency table; 20–30 targeted questions per topic.
Mixed Practice
Mixed sets under section timing (2 min/question). Keep an error log: concept, reading or calculation.
Full Mocks
One full 65-question CEnT-S mock per week with real section timers; review every wrong and every guessed answer.
Final Polish
Re-do your error log, revise traps, and practise the skip-or-guess rule for the −0.25 penalty.
