A force of 25 N is applied at right angles to a spanner at a point 0.20 m from the centre of a nut. What is the moment about the nut?

Q: How do I try a free AQA 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 AQA GCSE 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 AQA 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 AQA GCSE syllabus?

Every question is written against the published AQA GCSE 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 AQA past papers. Explanations are written in the style of official examiner mark schemes so students learn exactly what marks are being awarded for.

Question

A force of 25 N is applied at right angles to a spanner at a point 0.20 m from the centre of a nut. What is the moment about the nut?

Accepted Answer

5.0 N m — 0 N m. Award 1 mark. Multiplying 25 N by 0.20 m gives the turning effect. Dividing the force by the distance instead gives 125 and would grow as the spanner got shorter, which is the wrong way round.

Answer

25 N m

125 N m
