Moments, levers and gears (physics only)
Question
- A. The moment increases — calculation focus for moment
- B. This confuses distance and displacement and does not answer Moments and turning effects (physics only).
- C. This is too vague because it does not use the force or motion quantity named in the objective.
- D. This reverses the physical cause and effect for Moments, levers and gears (physics only).
Answer
The correct answer is: The moment increases — calculation focus for moment
Explanation
The correct option is The moment increases — calculation focus for moment. The moment increases — calculation focus for moment is correct because it matches the approved learning objective to (Physics only) Explain that increasing perpendicular distance increases the moment for a fixed force. This answer belongs to Moments and turning effects (physics only) within Moments, levers and gears (physics only), so it must use precise AQA GCSE Physics forces and motion vocabulary. The other options are wrong because they either confuse distance and displacement, omit the required force or motion condition, or move away from the exact subtopic being tested.
Common mistake
Misunderstanding Moment Calculation
Students often confuse the relationship between moment, force, and perpendicular distance, thinking that increasing either force or distance will always increase the moment without considering the fixed condition.
Emphasize that when explaining how increasing perpendicular distance increases the moment, it must be clear that the force remains constant. Use practical examples to illustrate this relationship.
