  • How can we increase the moment? mention 2 answer
    1.Increase the distance from the force to the pivot 2.Increase the force applied
  • 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
  • What are the units for moment
    Nm or Newton meter
  • Define " Moment "
    it's a turning effect
  • Calculate the moment!
    2 Nm
  • Calculate the distance of the objects from the fulcrum if the moment is 10 Nm
    1 m
  • Which letter shows where you should apply the effort?
    A
  • How to calculate moment ?
    moment = force x distance (from fulcrum)
  • which direction of this moment?
    anti-clockwise moment
  • [True or False] equilibrium is unbalanced
    False
  • How is the principle of moment help in making the beam balance?
    anti-clockwise moment = clockwise moment
  • In a balanced seesaw the total clockwise moment = total anticlockwise moment .True or False
    True
  • Which letter is the pivot?
    B
  • calculate the moment
    36 Nm
  • [True or False] Weight = mass x gravitational force
    True
  • 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] Gravitational force on Earth is 10 N/kg
    True
  • 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
  • calculate the moment
    20 Nm
