Forces and their interactions

Question

A. W = m x g — definition focus for W = mg
B. This confuses scalar and vector quantities 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: W = m x g — definition focus for W = mg

Explanation

The correct option is W = m x g — definition focus for W = mg. W = m x g — definition focus for W = mg is correct because it matches the approved learning objective to apply MS 3b and MS 3c skills when rearranging and using W = mg. 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 scalar and vector quantities, omit the required force or motion condition, or move away from the exact subtopic being tested.

Common mistake

Common Mistake in Weight Calculation

Students often confuse weight with mass when using the equation W = mg, leading to incorrect calculations.

Remember that weight (W) is a force measured in newtons, while mass (m) is measured in kilograms. Always ensure you are using the correct units and understand the distinction between the two.
