  • 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
  • How can we increase the moment? mention 2 answer
    1.Increase the distance from the force to the pivot 2.Increase the force applied
  • Calculate the distance of the objects from the fulcrum if the moment is 10 Nm
    10 m
  • [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
  • Which letter is the pivot?
    B
  • What are the units for moment
    Nm or Newton meter
  • 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
  • [True or False] Gravitational force on Earth is 10 N/kg
    True
  • calculate the moment
    force x distance = 6 Nm
  • calculate the moment
    20 Nm
  • Which letter shows where you should apply the effort?
    A
  • How to calculate moment ?
    moment = force x distance (from fulcrum)
  • Calculate the moment!
    2 Nm
  • Define " Moment "
    it's a turning effect
