Which of the following best defines the perpendicular distance used in calculating moments?

Q: How do I try a free CXC Physics question?

Just tap any of the four options on this page — no signup, no card, nothing to install. You'll see the correct answer and a full mark-scheme-style explanation within a second. Each visit shows a fresh randomly-picked question from the live CXC CSEC Physics bank, so you can keep refreshing to try different ones before deciding whether to create a free account for daily access.

Q: Is Kramizo really free for CXC Physics students?

Yes — completely free. Every student gets 45 questions a day on the free plan, across any board and any subject, with no card required and no trial countdown. Kramizo's optional Pro plan removes the daily cap and adds analytics, but the free plan is genuinely free forever. We make money from the small percentage of students who choose to upgrade — not from selling data or ads.

Q: Are the Physics questions aligned to the CXC CSEC syllabus?

Every question is written against the published CXC CSEC Physics syllabus and reviewed for accuracy before being added to the bank. We match the command words (state, describe, explain, evaluate), mark allocations, and difficulty tier you'll see on real CXC past papers. Explanations are written in the style of official examiner mark schemes so students learn exactly what marks are being awarded for.

Question

Which of the following best defines the perpendicular distance used in calculating moments?

Accepted Answer

The perpendicular distance from the pivot to the line of action of the force — Award 1 mark for C. This is the correct definition used in moment = force × perpendicular distance. A is incorrect — distance to point of application may not be perpendicular to force direction. B is incorrect — specifies horizontal only, not necessarily perpendicular to force. D is incorrect — distance along arm is not necessarily perpendicular to force line of action.

Answer

The perpendicular distance from the pivot to the line of action of the force

Answer

The shortest distance from the pivot to the point where force is applied

Answer

The horizontal distance from the pivot to the line of action of the force

Answer

The distance along the lever arm from the pivot to where force is applied
