What is a Moment or Moment of a Force?

The time taken for something to turn.

The turning effect of a force.

How do you calculate a Moment?

Moment = Force x Distance from Pivot Nm or Ncm= (N) (m or cm)

Moment = Mass x Gravity (N) = (kg) x (10)

Moment = Force / Area

In a test, if you are given mass instead of force what do you need to do?

Turn it into Weight

Turn it into Pressure

Turn it into Height

A girl is trying to unscrew a nut using a spanner. State TWO ways of increasing this turning effect

Use a shorter hammer

Use a longer hammer

Turn the spanner the other way

Use a bigger force

Use a heavier spanner

If a spanner is 30cm long and you are putting a force of 100N on it, what is the moment?

3000Ncm

3000Nm

300Ncm
