This exam focus covers Exam Focus within Moments & Levers for GCSE Physics. Revise Moments & Levers in Forces for GCSE Physics with 13 exam-style questions and 10 flashcards. This topic appears regularly enough that it should still be part of a steady revision cycle. It is section 12 of 14 in this topic. Treat this as a marking guide for what examiners are looking for, not just a fact list.
🎯 Exam Focus
Frequently Examined
Moments are examined on Edexcel 1PH0/1 (Paper 1, Foundation or Higher tier) and across all major GCSE Physics boards. Edexcel presents moments as practical scenarios ("A plank is balanced on a pivot…" or "A student uses a screwdriver…") and tests the principle of moments in context. Key question styles:
- Calculate a missing force or distance using the principle of moments — set up CW = ACW and solve
- State why a force is easier to apply further from the pivot — longer perpendicular distance = greater moment for same force
- Explain how a lever works — small force at large distance balances large force at small distance
- Gear ratio questions — larger gear to smaller gear increases speed; smaller to larger increases force
- Centre of mass (higher) — stability and toppling conditions
Mark scheme trap: "Perpendicular distance" must be stated in your answer when explaining moments — just saying "distance" will often lose a mark.
