Q1 · Difficulty 1/3
Sound waves are an example of which type of wave?
- electromagnetic
- water wave only
- transverse
- longitudinal
Show answer & explanation
✓ Answer: D — longitudinal
Sound travels as a longitudinal wave, with vibrations parallel to the direction of travel.
Q2 · Difficulty 1/3
A household in Kingston, Jamaica uses several electrical appliances including a refrigerator, television, and electric iron. Which safety device is designed to automatically disconnect the electricity supply if the current becomes too large?
- A fuse
- A resistor
- A transformer
- An ammeter
Show answer & explanation
✓ Answer: A — A fuse
Award 1 mark for identifying the fuse as the safety device that disconnects supply when current exceeds safe levels. B is incorrect — a resistor reduces current but does not disconnect the circuit. C is incorrect — a transformer changes voltage but provides no safety disconnection. D is incorrect — an ammeter measures current but does not disconnect the circuit.
Q3 · Difficulty 1/3
What is resistance?
- The charge in a circuit
- The flow of current
- The opposition to the flow of current in a conductor
- The voltage across a component
Show answer & explanation
✓ Answer: C — The opposition to the flow of current in a conductor
Resistance is a measure of how much a component opposes current flow. Unit: ohm (Ω). Higher resistance = less current for the same voltage.
Q4 · Difficulty 1/3
A student at a secondary school in Barbados was investigating the structure of atoms. She learned that atoms contain three types of subatomic particles. Which of the following particles has NO electrical charge?
- Neutron
- Electron
- Ion
- Proton
Show answer & explanation
✓ Answer: A — Neutron
Award 1 mark for identifying neutron as having no charge. D is incorrect because protons carry a positive charge. B is incorrect because electrons carry a negative charge. C is incorrect because an ion is a charged atom, not a subatomic particle.
Q5 · Difficulty 1/3
The SI unit of electric charge is the:
- ohm
- ampere
- volt
- coulomb
Show answer & explanation
✓ Answer: D — coulomb
Award 1 mark for identifying the coulomb (D) as the SI unit of charge. B is incorrect — ampere is the unit of current. C is incorrect — volt is the unit of potential difference. A is incorrect — ohm is the unit of resistance.
Q6 · Difficulty 1/3
Which logic gate produces a HIGH output only when ALL of its inputs are HIGH?
- NOT gate
- NOR gate
- OR gate
- AND gate
Show answer & explanation
✓ Answer: D — AND gate
Award 1 mark for identifying that an AND gate requires all inputs to be HIGH (1) to produce a HIGH output. C is incorrect — an OR gate produces HIGH when at least one input is HIGH. A is incorrect — a NOT gate is an inverter with only one input. B is incorrect — a NOR gate produces HIGH only when all inputs are LOW.
Q7 · Difficulty 1/3
A farmer in rural Jamaica uses a lever to lift a heavy stone weighing 600 N. He applies an effort of 150 N. What is the mechanical advantage of this lever?
- 750
- 0.25
- 4
- 450
Show answer & explanation
✓ Answer: C — 4
Award 1 mark for correctly applying MA = Load/Effort = 600/150 = 4. B is incorrect — this is Effort/Load (inverted formula). D is incorrect — this is Load minus Effort. A is incorrect — this is Load plus Effort.
Q8 · Difficulty 1/3
What is voltage (potential difference)?
- The resistance of a wire
- The speed of electrons
- The flow of electrons
- The energy transferred per unit charge passing between two points
Show answer & explanation
✓ Answer: D — The energy transferred per unit charge passing between two points
Potential difference (voltage) is the energy transferred per coulomb of charge. V = E/Q. Unit: volt (V).
CXC CSEC Physics FAQ
What does the CXC CSEC Physics exam look like?
The CXC CSEC Physics exam is structured across 3 components. Paper 1 (Section A): 60 multiple-choice questions, 1 mark each. 75 minutes. Tests knowledge across the whole syllabus. Paper 2: Structured short-answer + 1 extended response question. Section A is compulsory; Section B has a choice. Approximately 2 hours 10 minutes. School-Based Assessment (SBA): Coursework component graded by the teacher, externally moderated. Worth ~20-30% of the final grade depending on subject. Total exam time: ~3.5 hours across Paper 1 and Paper 2 sittings.
Can I download a free CXC CSEC Physics past paper?
Real CXC past papers are published directly by CXC on their official website. Kramizo doesn't redistribute copyrighted past papers, but we do generate free AI-written practice papers in the exact same style — same command words, same difficulty tier, same mark conventions. Use this practice paper as warm-up, then time yourself on official past papers before exam day.
How is CXC CSEC Physics graded?
Grades: I (highest) to VI (lowest). A grade of III or above is typically required for further study. Kramizo's practice questions are tagged with difficulty 1-3 mapping roughly to the lower, middle, and top grade boundaries you'll encounter in the real exam.
