      "When do we have the quiz?"
      You will have a quiz tomorrow since there was no school on Monday.
      5 questions.

      What is the difference between input force and output force
      What are two ways a machine makes work easier?
      How can machines be made more efficient?
      How does using a ramp to put items in a truck make work easier?
      How does using a hammer to a nail boards together make work easier?
