1Which of the following is a base SI unit?
A.Newton
B.Joule
C.Volt
D.Kelvin
Explanation: The seven SI base units are the metre, kilogram, second, ampere, kelvin, mole and candela. The kelvin is the base unit of thermodynamic temperature.
2The pressure p of a gas is given by p = ⅓ ρ⟨c²⟩, where ρ is density and ⟨c²⟩ is mean-square speed. What are the base SI units of pressure derived from this expression?
A.kg m s⁻²
B.kg m⁻³ s⁻²
C.kg m⁻² s⁻¹
D.kg m⁻¹ s⁻²
Explanation: Density has units kg m⁻³ and ⟨c²⟩ has units m² s⁻². Multiplying gives kg m⁻³ × m² s⁻² = kg m⁻¹ s⁻², which equals the pascal (N m⁻²).
3A micrometer screw gauge has a smallest scale division of 0.01 mm. A student records a wire diameter as 0.54 mm. What is the percentage uncertainty in this single reading, taking the uncertainty as one smallest division?
A.0.5%
B.1.9%
C.5.4%
D.0.18%
Explanation: The absolute uncertainty is 0.01 mm. Percentage uncertainty = (0.01 / 0.54) × 100% ≈ 1.85%, which rounds to about 1.9%.
4A quantity P is calculated from P = a²b / √c. If the percentage uncertainties in a, b and c are 2%, 3% and 4% respectively, what is the percentage uncertainty in P?
A.5%
B.9%
C.7%
D.11%
Explanation: Fractional uncertainties combine by adding, weighted by the power of each quantity: ΔP/P = 2(2%) + 1(3%) + ½(4%) = 4% + 3% + 2% = 9%.
5Which statement best distinguishes a systematic error from a random error?
A.A systematic error can be reduced by repeating readings and averaging
B.A systematic error shifts all readings in the same direction by a consistent amount
C.A random error always makes readings too large
D.A random error can be eliminated by recalibrating the instrument
Explanation: A systematic error displaces every reading by a fixed bias in the same direction (for example a zero error), so averaging does not remove it. It affects accuracy.
6Two forces of 3.0 N and 4.0 N act at a point at right angles to each other. What is the magnitude of their resultant?
A.1.0 N
B.5.0 N
C.7.0 N
D.12 N
Explanation: For perpendicular vectors the resultant magnitude is √(3.0² + 4.0²) = √25 = 5.0 N, using the Pythagorean theorem.
7A ball is thrown vertically upward with an initial speed of 20 m s⁻¹. Taking g = 9.81 m s⁻² and ignoring air resistance, what is the maximum height reached?
A.10.2 m
B.20.4 m
C.40.8 m
D.2.04 m
Explanation: At maximum height v = 0. Using v² = u² − 2gh: 0 = 20² − 2(9.81)h, so h = 400 / 19.62 ≈ 20.4 m.
8A projectile is launched at 30 m s⁻¹ at 60° above the horizontal. Ignoring air resistance, what is the horizontal component of its velocity throughout the flight?
A.26 m s⁻¹
B.30 m s⁻¹
C.It increases steadily
D.15 m s⁻¹
Explanation: The horizontal velocity component is u cosθ = 30 cos60° = 30 × 0.5 = 15 m s⁻¹. With no air resistance the horizontal component stays constant since there is no horizontal force.
9Newton's second law is most generally stated as which of the following?
A.Force equals mass times velocity
B.Force equals the rate of change of momentum
C.Every action has an equal and opposite reaction
D.A body remains at rest unless acted on by a force
Explanation: Newton's second law states that the resultant force equals the rate of change of momentum (F = d(mv)/dt). For constant mass this reduces to F = ma.
10A 1200 kg car accelerates from rest to 20 m s⁻¹ in 8.0 s. What is the average resultant force on the car?
A.1500 N
B.24000 N
C.192 N
D.3000 N
Explanation: Acceleration a = Δv/Δt = 20/8.0 = 2.5 m s⁻². Resultant force F = ma = 1200 × 2.5 = 3000 N.

About the A-Level H2 Physics Exam

The Singapore-Cambridge GCE A-Level H2 Physics examination (Syllabus 9749) is taken at the end of Junior College 2 (JC2) by students intending to read science, engineering or medicine at university. It is assessed through four papers: Paper 1 with 30 compulsory multiple-choice questions (30 marks, 15%), Paper 2 structured questions (80 marks, 30%), Paper 3 longer structured and free-response questions (80 marks, 35%), and a Paper 4 practical assessment (55 marks, 20%). The syllabus is organised into six sections covering 20 topics: Measurement, Newtonian Mechanics, Thermal Physics, Oscillations and Waves, Electricity and Magnetism, and Modern Physics. Candidates are awarded grades A to E for a pass, with S and U below. 9749 sits its final examination in 2026 as it is replaced by syllabus 9478 for cohorts entering JC1 from 2025.

A-Level H2 Physics Study Tips from Top Performers

1Master the SEAB Data and Formulae sheet early - it lists constants and key equations, so know which formulas are given and which you must recall and rearrange.
2Practise Paper 1 MCQs under timed conditions: 30 questions in 60 minutes means roughly two minutes each, including quick proportional-reasoning checks.
3Drill cross-topic synthesis questions for Paper 3 Section B, where electromagnetic induction may combine mechanics, fields, and energy conservation in one problem.
4Always carry units through calculations and state answers to an appropriate number of significant figures, since marks are lost for unit and rounding errors.
5Prepare deliberately for Paper 4 by rehearsing graph plotting, error analysis, and planning experiments, as the practical is worth 20% of the grade.
