🎯 Exam Focus
Frequently Examined
Moments calculations appear in AQA Physics Paper 1 regularly, often worth 3-4 marks. 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.
