    A
  • [True or False] Weight = mass x gravitational force
    True
  • calculate the moment
    20 Nm
  • calculate the moment
    force x distance = 6 Nm
  • What are the units for moment
    Nm or Newton meter
  • Calculate the moment!
    2 Nm
  • How to calculate moment ?
    moment = force x distance (from fulcrum)
  • Which letter is the pivot?
    B
  • A simple machine which consists of a beam resting on a pivot that help us carry heavy objects is called_____
    A lever
  • How can we increase the moment? mention 2 answer
    1.Increase the distance from the force to the pivot 2.Increase the force applied
  • 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
  • Define " Moment "
    it's a turning effect
  • [True or False] Gravitational force on Earth is 10 N/kg
    True
  • 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
  • Calculate the distance of the objects from the fulcrum if the moment is 10 Nm
    10 m
