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
