Apply MS 3b and MS 3c skills when rearranging and using W = mg.

In the subtopic Gravity and weight, this learning objective focuses on apply MS 3b and MS 3c skills when rearranging and using W = mg. For AQA GCSE Physics 8463 Unit 4.5 Forces, keep the explanation inside Gravity and weight and Forces and their interactions. Approved keywords for this objective include W = mg. A strong answer separates scalar and vector quantities, uses correct units where quantities are involved, and links the physical reasoning back to apply MS 3b and MS 3c skills when rearranging and using W = mg. This is not a generic revision point: it is specifically about Gravity and weight, Forces and their interactions, and the approved wording of the learning objective.
