Understand this objective

Short explanation

In the subtopic Gravity and weight, this learning objective focuses on state that weight acts through the centre of mass of an object. 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 weight, mass, and centre of mass. A strong answer separates mass and weight, uses correct units where quantities are involved, and links the physical reasoning back to state that weight acts through the centre of mass of an object. 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.
