### Question 1

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

### Question 2

Question
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

### Question 3

Question
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

### Question 4

Question
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

### Question 5

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