Levers and Pulleys Unit Test

Posted by iateacher on December 13, 2007

Hello parents, guardians and students,

We are quickly coming to the end of our Levers and Pulleys Unit.  😦  I think it was a lot of fun!  I am planning on the final unit test being next THURSDAY, DECEMBER 20.  There are items below to study.  Also, this time I did take the time to make an online test which you can find here.  Hope all of this will help!

Now, on to the study guide:


  • lever
  • load
  • fulcrum
  • effort
  • Newton
  • diagram
  • advantage
  • pulley
  • simple machine


  • Be prepared to correctly read a spring scale
  • Be prepared to correctly diagram one or more lever systems (using the proper symbols)
  • Be able to correctly label several real-world levers with the load, fulcrum and effort symbols and direction of force
  • Be able to tell which pulley systems WILL and WILL NOT provide the user with an advantage by reducing the effort
  • Be able to calculate the effort needed to lift a load in a particular pulley system
  • Know how far one must pull the rope in order to move the load specified distance
  • Be able to identify pulley systems that WILL and WILL NOT work properly
  • Explain how to load a large boulder into a truck using a lever and a pulley

The test will be 49 points.  If students have questions about any of the following I encourage them to see me BEFORE the test day for help!
