Question 1 · 1 mark · Difficulty 1/3

A worker at a sugar cane processing plant in St. Kitts uses a crowbar to lift a heavy metal lid. The worker applies a force of 200 N at a distance of 1.5 m from the pivot. What is the moment of the force about the pivot?

  1. 133 N m
  2. 200 N m
  3. 300 N m
  4. 400 N m
Show answer & explanation
✓ Answer: C — 300 N m
Award 1 mark for correct calculation using moment = force × perpendicular distance from pivot = 200 N × 1.5 m = 300 N m. A is incorrect — divides force by distance instead of multiplying. B is incorrect — uses only the force value, omitting distance. D is incorrect — doubles the correct answer, possibly calculating 200 × 2.
Question 2 · 1 mark · Difficulty 2/3

A fisherman in Barbados uses a fishing rod that acts as a lever. He holds the rod 0.4 m from the pivot point and a fish exerts a downward force of 50 N at 2.0 m from the pivot. Which statement correctly describes the moments?

  1. The fish creates a clockwise moment of 100 N m
  2. The fish creates an anticlockwise moment of 100 N m
  3. The fisherman must apply a force of 50 N to balance the fish
  4. The total moment about the pivot is 2.4 N m
Show answer & explanation
✓ Answer: B — The fish creates an anticlockwise moment of 100 N m
Award 1 mark for recognizing moment = 50 N × 2.0 m = 100 N m in the anticlockwise direction (assuming standard setup). A is incorrect — direction error, fish pulling down creates anticlockwise moment. C is incorrect — force needed depends on distance: 100/0.4 = 250 N. D is incorrect — confuses distance with moment.

CXC CSEC Physics: Turning Effect of Forces: Moments and the Principle of Moments FAQ

How many CXC CSEC Physics questions on Turning Effect of Forces: Moments and the Principle of Moments are there on Kramizo?
Kramizo currently has 20 exam-board-aligned practice questions on Turning Effect of Forces: Moments and the Principle of Moments 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 Turning Effect of Forces: Moments and the Principle of Moments 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 Turning Effect of Forces: Moments and the Principle of Moments 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 Turning Effect of Forces: Moments and the Principle of Moments typically tested on CXC CSEC Physics papers?
Turning Effect of Forces: Moments and the Principle of Moments 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.
