Short explanation

In the subtopic Levers and gears (physics only), this learning objective focuses on (Physics only) Describe how a smaller gear driven by a larger gear changes rotation speed and turning effect. 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 gear, turning effect, rotation, and physics only. A strong answer separates speed and velocity, uses correct units where quantities are involved, and links the physical reasoning back to (Physics only) Describe how a smaller gear driven by a larger gear changes rotation speed and turning effect. 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.

Common mistakes

Gear speed vs. turning effect confusion: Explain that the larger gear provides a greater turning effect (torque) but the smaller gear rotates faster; the two effects are inversely related and cannot both increase simultaneously.
