Revise: RotationThe turning effect of a force about a pivot is called a moment.
The turning effect of a force about a pivot or axis.
Specification P2.3m · Paper 1 (Foundation), Paper 3 (Higher)
The turning effect of a force about a pivot, equal to the force multiplied by its perpendicular distance from the pivot.
Revise: Levers and gearsBy changing the distances involved, they can make a smaller input force produce a larger output force or turning moment.
Paper 1, Paper 2
The turning effect produced by a force about a point, measured in newton metres.
Revise: Circular Motion, Moments, Levers and GearsThe turning effect is called the moment of the force.
Do not describe a moment as a force: a moment is measured in newton-metres (Nm), not newtons (N).
Identify the input and output before using a ratio: a larger driven gear turns more slowly but produces a greater turning moment.
In a moment calculation, use the perpendicular distance from the pivot to the force’s line of action, not automatically the length of the lever.
