Moments

• What is the turning effect of a force called?

  Moment
• How is the moment of a force calculated?

  Moment (Nm) = Force (N) x Distance (m)
• What does the distance in the moment formula represent?

  The perpendicular distance from the pivot to the force line
• What happens to the moment if a longer spanner is used?

  The moment increases
• What is the optimal angle to push for maximum moment?

  At right angles
• What occurs if the force is applied at an angle other than right angles?

  It results in a smaller moment
• What condition must be met for an object to be balanced at a pivot?

  Total anticlockwise moment equals total clockwise moment
• What happens to an object if the moments are balanced about a pivot?

  It won't turn
