5.4.1 Moments of a Force

Cards (25)

  • The formula for calculating a moment is moment = force × perpendicular distance
  • What does the perpendicular distance in the moment formula refer to?
    Shortest distance from force to pivot
  • The larger the force applied, the larger the moment
  • What does the principle of moments state for an object in equilibrium?
    Clockwise moment = anticlockwise moment
  • What units are used to measure moments?
    Newton-meters (N-m)
  • Match the type of moment with its direction:
    Clockwise Moment ↔️ Right
    Anticlockwise Moment ↔️ Left
  • What are the two main factors that affect the size of a moment?
    Force and perpendicular distance
  • Match the term with its definition and units:
    Moment ↔️ Turning effect of a force (N-m)
    Force ↔️ Push or pull on an object (N)
    Perpendicular Distance ↔️ Shortest distance to pivot (m)
  • The effect of force on a moment is directly proportional
  • What is the moment of a force?
    Turning effect around a pivot
  • Order the factors affecting the size of a moment from most to least effect.
    1️⃣ Force
    2️⃣ Perpendicular Distance
  • What are some practical applications of moment calculations?
    Levers, wrenches, beam balances
  • What is the moment of a force defined as?
    Turning effect around a pivot
  • The principle of moments states that for an object to be in equilibrium, the total clockwise moment must equal the total anticlockwise moment
  • How is the unit for moments (N-m) derived?
    Force in Newtons and distance in meters
  • The larger the force or the further the distance from the pivot, the larger the moment produced.
    True
  • The perpendicular distance must be measured from the pivot to the line of action of the force.

    True
  • The principle of moments states that for an object in equilibrium, the total clockwise moment equals the total anticlockwise moment
  • In a beam balance, moment calculations are used to ensure balance
  • Moments are measured in Newton-meters (N-m).

    True
  • The distance in the moment calculation must be perpendicular to the force
  • The further the line of action of the force is from the pivot, the smaller the moment.
    False
  • The formula to calculate a moment is: moment = force × perpendicular distance
  • Moments are measured using force in Newtons and perpendicular distance in meters.
    True
  • The net moment acting on an object in equilibrium is zero.
