Q1 · Difficulty 1/3

Which of the following correctly states the relationship between electric current and charge?

  1. Current is the energy carried by charges
  2. Current is the charge stored in a conductor
  3. Current is the rate of flow of charge
  4. Current is the force that moves charges
Show answer & explanation
✓ Answer: C — Current is the rate of flow of charge
Award 1 mark for identifying current as charge per unit time (I = Q/t). B is incorrect — charge storage describes capacitance, not current. D is incorrect — this describes potential difference or electromotive force. A is incorrect — this confuses current with electrical energy or power.
Q2 · Difficulty 1/3

A uniform ladder of length 6.0 m and weight 200 N leans against a smooth vertical wall in Trinidad. The ladder makes an angle of 60° with the horizontal ground. The foot of the ladder is 3.0 m from the wall. Where does the weight of the ladder act?

  1. At the top of the ladder
  2. At the foot of the ladder
  3. At the midpoint of the ladder, 3.0 m from either end
  4. At a point 2.0 m from the foot of the ladder
Show answer & explanation
✓ Answer: C — At the midpoint of the ladder, 3.0 m from either end
0 m from either end. Award 1 mark for “At the midpoint of the ladder, 3.0 m from either end”. For a uniform body, the weight acts at the centre of mass, which for a uniform ladder is at its geometric centre (midpoint). “At the top of the ladder” is incorrect — weight does not act at the top. “At the foot of the ladder” is incorrect — weight does not act at the foot. “At a point 2.0 m from the foot of the ladder” is incorrect — this is not the centre of the ladder.
Q3 · Difficulty 1/3

What is the output of a NOT gate when the input is 1?

  1. 0
  2. 1
  3. 2
  4. Undefined
Show answer & explanation
✓ Answer: A — 0
Award 1 mark for stating that a NOT gate inverts its input, so an input of 1 produces an output of 0. B is incorrect — this would mean no inversion occurred. C is incorrect — logic gates only produce binary outputs (0 or 1). D is incorrect — a NOT gate always produces a defined output.
Q4 · Difficulty 1/3

What do all electromagnetic waves have in common?

  1. They are all visible
  2. They are all longitudinal
  3. They all need a medium
  4. They all travel at the same speed in a vacuum (3 × 10⁸ m/s) and are transverse
Show answer & explanation
✓ Answer: D — They all travel at the same speed in a vacuum (3 × 10⁸ m/s) and are transverse
All EM waves are transverse, travel at 3 × 10⁸ m/s in a vacuum, and can travel without a medium. They differ in wavelength and frequency.
Q5 · Difficulty 1/3

What is infrared radiation used for?

  1. Medical X-rays
  2. TV remote controls, thermal imaging, and heating
  3. Radio broadcasting
  4. Sterilising equipment
Show answer & explanation
✓ Answer: B — TV remote controls, thermal imaging, and heating
Infrared radiation is used in remote controls, thermal imaging cameras, toasters, heaters, and fibre optic communication.
Q6 · Difficulty 1/3

Which of the following is the SI unit for electric current?

  1. Coulomb (C)
  2. Volt (V)
  3. Ohm (Ω)
  4. Ampere (A)
Show answer & explanation
✓ Answer: D — Ampere (A)
Award 1 mark for identifying the ampere as the SI unit for electric current. B is incorrect — the volt is the unit for potential difference. C is incorrect — the ohm is the unit for resistance. A is incorrect — the coulomb is the unit for electric charge, not current.
Q7 · Difficulty 1/3

What is the electromagnetic spectrum?

  1. Only visible light
  2. The full range of electromagnetic waves from radio waves to gamma rays
  3. Sound waves of different frequencies
  4. Only ultraviolet and infrared
Show answer & explanation
✓ Answer: B — The full range of electromagnetic waves from radio waves to gamma rays
The electromagnetic spectrum includes (in order of increasing frequency): radio, microwave, infrared, visible light, ultraviolet, X-rays, and gamma rays.
Q8 · Difficulty 1/3

What type of wave is sound?

  1. Seismic
  2. Transverse
  3. Electromagnetic
  4. Longitudinal
Show answer & explanation
✓ Answer: D — Longitudinal
Sound is a longitudinal wave — it travels through a medium by compressing and rarefying particles. It cannot travel through a vacuum.

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.
