Common mistake

Misunderstanding Moment Units

Students often confuse the unit of moment, stating it as newtons instead of newton metres.

Remember that moment is defined as the turning effect of a force and is measured in newton metres (Nm), which combines force (N) and distance (m) from the pivot.
