Common mistake
Gear speed vs. turning effect confusion
Students often think that a smaller gear driven by a larger gear both increases rotation speed and increases the turning effect, treating the two effects as the same.
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.
