Question 1 · 1 mark · Difficulty 1/3

Which of the following energy sources is classified as a non-renewable resource?

  1. Geothermal energy from volcanic activity
  2. Energy from tidal movements in the ocean
  3. Solar energy from photovoltaic panels
  4. Natural gas extracted from underground reserves
Show answer & explanation
✓ Answer: DNatural gas extracted from underground reserves
Natural gas is a fossil fuel formed over millions of years and cannot be replenished on a human timescale, making it non-renewable. Solar, tidal, and geothermal energy are all continuously replenished by natural processes and are therefore classified as renewable resources.
Question 2 · 1 mark · Difficulty 1/3

A student in Jamaica observes a coconut falling from a tree. As the coconut falls, which energy transformation occurs?

  1. Kinetic energy to gravitational potential energy
  2. Gravitational potential energy to kinetic energy
  3. Chemical energy to kinetic energy
  4. Kinetic energy to chemical energy
Show answer & explanation
✓ Answer: BGravitational potential energy to kinetic energy
Award 1 mark for identifying that stored energy due to height (gravitational potential energy) converts to energy of motion (kinetic energy) as the coconut falls. A is incorrect because this describes an object moving upward. C is incorrect because chemical energy is not involved in falling. D is incorrect because it reverses the correct transformation.

CXC CSEC Physics: Energy, Work and Power FAQ

How many CXC CSEC Physics questions on Energy, Work and Power are there on Kramizo?
Kramizo currently has 67 exam-board-aligned practice questions on Energy, Work and Power for CXC CSEC Physics, with new questions added every week. Each question gives you instant feedback and a full examiner-style mark scheme that tells you exactly what would earn marks on a real CXC paper. The questions span the full difficulty range — from straightforward recall (level 1) right up to multi-step reasoning and evaluation (level 3) — so the bank works for first-pass revision and final exam-week stress testing alike.
Is Kramizo free for CXC CSEC students preparing for Physics?
Yes — completely free. Every student gets 45 questions a day on the free plan, with no card required and no trial countdown. That free quota works across every subject and every topic in our bank, so you can mix Energy, Work and Power practice with other Physics topics or even switch to a totally different CXC subject without paying anything. Kramizo's optional Pro plan removes the daily cap and adds detailed progress analytics, but the free tier is the real product — used by thousands of GCSE, IGCSE and CSEC students.
Are the Energy, Work and Power questions aligned to the official CXC CSEC Physics syllabus?
Every question is written against the published CXC CSEC Physics specification, including the exact command words (state, describe, explain, calculate, evaluate, etc.), mark allocations, and difficulty tier you'd see on a real CXC paper. Explanations are written in the style of official examiner mark schemes — they tell you what is being awarded marks and why distractors are wrong, not just whether you got it right. The bank is continually refined to match the latest syllabus updates from CXC.
How is Energy, Work and Power typically tested on CXC CSEC Physics papers?
Energy, Work and Power appears across multiple question types on real CXC CSEC Physics papers — most commonly as multiple-choice questions in the objective section, structured short-answer questions in the main paper, and occasionally as part of an extended response. Kramizo's practice bank reflects that mix: 4-option MCQs, true/false statements, fill-in-the-blank key terms, multi-select questions, and ordering questions. Working through the bank gives you exposure to every question style examiners actually use.
