Short explanation

In the subtopic Levers and gears (physics only), this learning objective focuses on (Physics only) Identify input gear and output gear in simple gear diagrams. For AQA GCSE Physics 8463 Unit 4.5 Forces, keep the explanation inside Levers and gears (physics only) and Moments, levers and gears (physics only). Approved keywords for this objective include physics only and gear. A strong answer separates moment and force, uses correct units where quantities are involved, and links the physical reasoning back to (Physics only) Identify input gear and output gear in simple gear diagrams. This is not a generic revision point: it is specifically about Levers and gears (physics only), Moments, levers and gears (physics only), and the approved wording of the learning objective.
