Question

Newton metres

Moment is measured in newton metres (Nm), which reflects the turning effect of a force applied at a distance from a pivot.

Misunderstanding force reduction

Students think a longer lever arm increases the required force to achieve the same moment, rather than reducing it.

Explain that moment M = F × d; for a fixed M, increasing the perpendicular distance d means the force F must decrease proportionally (F = M/d).
