What is a moment and what units is it measured in?
A moment is the turning effect caused by a force acting on an object that can rotate around a pivot point.
It is measured in newton-metres (Nm).

What two variables determine the size of a moment?
1. Force (F) - measured in newtons (N).
2. Perpendicular distance from the pivot (d) - measured in metres (m).

What is the formula to calculate a moment?
Moment (Nm) = Force (N) × Perpendicular distance from pivot (m)

What is the result of balanced moments?
When moments are balanced, there is no net rotational effect, and the object remains stationary.

What happens when moments are unbalanced?
Unbalanced moments result in rotation around the pivot point.
