1.25 know and use the relationship between the moment of a force and its distance from the pivot: moment = force × perpendicular distance from the pivot

Formula:

moment = force x distance from pivot

Moments are measured in Nm or Ncm
Force is measured in N
Distance is measured in m or cm


Remember! If it says mass is 100g that you need to convert that into Newtons:

1 kg = 10N
100g = 1N

The formula can be rearranged to form:

force =        moment          
            distance from pivot
distance from pivot = moment
                                     force

Examples:

1. Calculate the moment on the right side = 0.5 x     5 = 2.5 Ncm
2. 2.5Ncm = ? ÷ 0.25
3. ? = 10 N
