Question
What is a Moment or Moment of a Force?
Answer
  • The time taken for something to turn.
  • The turning effect of a force.

Question 2

Question
How do you calculate a Moment?
Answer
  • Moment = Force x Distance from Pivot Nm or Ncm= (N) (m or cm)
  • Moment = Mass x Gravity (N) = (kg) x (10)
  • Moment = Force / Area

Question 3

Question
In a test, if you are given mass instead of force what do you need to do?
Answer
  • Turn it into Weight
  • Turn it into Pressure
  • Turn it into Height

Question 4

Question
A girl is trying to unscrew a nut using a spanner. State TWO ways of increasing this turning effect
Answer
  • Use a shorter hammer
  • Use a longer hammer
  • Turn the spanner the other way
  • Use a bigger force
  • Use a heavier spanner

Question 5

Question
If a spanner is 30cm long and you are putting a force of 100N on it, what is the moment?
Answer
  • 3000Ncm
  • 3000Nm
  • 300Ncm
