  • How can we increase the moment? mention 2 answer
    1.Increase the distance from the force to the pivot 2.Increase the force applied
  • which direction of this moment?
    anti-clockwise moment
  • What are the units for moment
    Nm or Newton meter
  • How is the principle of moment help in making the beam balance?
    anti-clockwise moment = clockwise moment
  • The figure shows a man lifting a heavy rock using a steel bar. He pushes downwards on the end of the bar with a force F. Which pivot positions allows the force F to be as small as possible?
    A
  • Define " Moment "
    it's a turning effect
  • How to calculate moment ?
    moment = force x distance (from fulcrum)
  • A simple machine which consists of a beam resting on a pivot that help us carry heavy objects is called_____
    A lever
  • [True or False] equilibrium is unbalanced
    False
  • Which letter shows where you should apply the effort?
    A
  • Calculate the distance of the objects from the fulcrum if the moment is 10 Nm
    1 m
  • A seesaw is unbalanced with two people of different masses sitting equal distances from the fulcrum. How we can move the smaller mass to make the seesaw balanced? closer to the fulcrum or further to the fulcrum?
    further from the fulcrum
  • In a balanced seesaw the total clockwise moment = total anticlockwise moment .True or False
    True
  • [True or False] Weight = mass x gravitational force
    True
  • [True or False] Gravitational force on Earth is 10 N/kg
    True
  • calculate the moment
    36 Nm
  • Calculate the moment!
    2 Nm
  • calculate the moment
    20 Nm
  • Which letter is the pivot?
    B
