• what is a moment

  • the turning effect of the force
  • moment = force x distance|
• What is an alternative name for the turning effect of a force?

  A moment.
• What is the equation used to calculate the moment of a force?

  Moment of force = Force x Distance
• What are the appropriate units for moment, force, and distance?

  Moment (Nm), Force (N), Distance (m)
• What distance measurement is used when calculating a moment?

  The perpendicular distance from the pivot.
• What can be said about the moments acting on an object in equilibrium?

  The clockwise moments are equal to the anticlockwise moments.
• How do levers make use of moments?

  They increase the perpendicular distance from the pivot so decrease the force needed to create the same moment
• Will the object rotate if the clockwise and anticlockwise moments are equal?

  No, it remains in equilibrium because the anticlockwise moment is equal to the clockwise moment
• How are levers used to decrease the force required to lift something?

  They use a pivot and moments to reduce force.The further you are away from a pivot point the less force is required to life you up
• How does lubricating levers and gears improve efficiency?

  There is less resistance and energy wasted.
