Moments, levers and gears (physics only)
Question
- A. moment = force x distance — definition focus for pivot
- 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: moment = force x distance — definition focus for pivot
Explanation
The correct option is moment = force x distance — definition focus for pivot. moment = force x distance — definition focus for pivot is correct because it matches the approved learning objective to (Physics only) Use the equation moment of a force = force x perpendicular distance from the pivot. 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 moment equation by mixing up the force and perpendicular distance, leading to incorrect calculations.
To fix this, always remember that the moment is calculated using the formula: moment = force x perpendicular distance from the pivot. Ensure you identify the correct values for force and distance before substituting them into the equation.
