Question

A. At the centre of mass of the object — definition focus for weight
B. This confuses mass and weight and does not answer Gravity and weight.
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 Forces and their interactions.

Answer

The correct answer is: At the centre of mass of the object — definition focus for weight

Explanation

The correct option is At the centre of mass of the object — definition focus for weight. At the centre of mass of the object — definition focus for weight is correct because it matches the approved learning objective to state that weight acts through the centre of mass of an object. This answer belongs to Gravity and weight within Forces and their interactions, so it must use precise AQA GCSE Physics forces and motion vocabulary. The other options are wrong because they either confuse mass and weight, omit the required force or motion condition, or move away from the exact subtopic being tested.

Common mistake

Confusing Weight and Mass

Students often confuse weight with mass, thinking they are the same quantity.

Remember that weight is a force measured in newtons and acts through the centre of mass, while mass is a scalar quantity measured in kilograms.
