Review

• And suggestions for studying

Read Chapter 5

• I suggest reading the chapter. As you get to the
  end of each section, ask yourself the question
  then look at the given answer to see if you are
  right. If not, go back and look it up and reread
  that section.

3
Simple Machines

• Know all the simple machines, their individual
  parts, examples and definitions.
• Refer to the PowerPoint and to the Simple but
  Tough notes.

How Machines Make Work Easier

• PowerPoint
• 1. They can change the amount of force required
  wedge, lever, wheel axle, Pulley
• 2. They can change the distance over which the
  force is exerted inclined plane, screw, lever,
  wheel axle
• 3. They can change the direction of the input
  force pulley, lever

5
Work

• Simple machines DO NOT change the amount of work
  done.
• From PowerPoint

More Work

• For work to be done, what things must happen?
  (PowerPoint)
• 1. Force must be applied
• 2. Object must move some distance as a result of
  the force applied
• 3. Force applied must be in the same direction
  as the motion of the object

7
SI Units

• Refer to the Calculating Work worksheet
• Each unit was on the board
• Force is measured in Newtons
• Distance is measured in Meters
• Work is measured in Joules
• One joule is equal to one Newton-Meter

8
Calculating Work

• Refer to the Calculating Work worksheet
• We worked all 6 problems together on the board,
  so you should have detailed notes on how to solve
  these.

9
Forces and Simple Machines Notes

• If you dont have yours, refer to the downloads
  for the first six weeks. They are dated 9/14.

10
Gizmos and StemScopes

• I would try to answer the 5 questions that go
  with the Gizmo we did in the computer lab. I
  would also finish the Gizmo if you havent.
• I would log in to StemScopes and try the 3
  practice quizzes, keeping in mind that this test
  is over simple machines and work ONLY, not the
  life science questions.

11
Vocabulary

• Be sure you can define each of the words in the
  vocabulary list. For simple machines, be sure
  you can list examples of each as well.
