Question 1 · 1 mark · Difficulty 1/3

Which of the following is the correct definition of work done?

  1. Work done = force × distance moved in the direction of the force
  2. Work done = force × time taken
  3. Work done = mass × acceleration × distance
  4. Work done = power × distance
Show answer & explanation
✓ Answer: AWork done = force × distance moved in the direction of the force
Award 1 mark for correctly stating that work done equals force multiplied by distance moved in the direction of the force. B is incorrect — this describes impulse, not work. C is incorrect — while force equals mass × acceleration, this is not the definition of work. D is incorrect — power equals work done divided by time, so work done equals power × time, not power × distance.
Question 2 · 1 mark · Difficulty 1/3

A student pushes a trolley with a constant horizontal force of 40 N across a floor. The trolley moves 8.0 m in the direction of the force. How much work is done on the trolley?

  1. 5.0 J
  2. 32 J
  3. 48 J
  4. 320 J
Show answer & explanation
✓ Answer: D320 J
Award 1 mark for correct calculation: W = F × d = 40 × 8.0 = 320 J. A is incorrect — this results from dividing force by distance. B is incorrect — this is an arithmetic error. C is incorrect — this results from adding force and distance then multiplying incorrectly.

CIE IGCSE Physics: Work and power FAQ

How many CIE IGCSE Physics questions on Work and power are there on Kramizo?
Kramizo currently has 20 exam-board-aligned practice questions on Work and power for CIE IGCSE 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 CIE 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 CIE IGCSE 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 Work and power practice with other Physics topics or even switch to a totally different CIE 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 Work and power questions aligned to the official CIE IGCSE Physics syllabus?
Every question is written against the published CIE IGCSE Physics specification, including the exact command words (state, describe, explain, calculate, evaluate, etc.), mark allocations, and difficulty tier you'd see on a real CIE 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 CIE.
How is Work and power typically tested on CIE IGCSE Physics papers?
Work and power appears across multiple question types on real CIE IGCSE 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.
