3.  Simple Machines are the tools that magnifies effort

4.  a rigid bar that pivots about one point and that is used to move an object at a second point by a force applied at a third.

5.  a part, as a disk, wheel, or section of a shaft, having cut teeth of such form, size, and spacing that they mesh with teeth in another part to transmit or receive force and motion.

6.  A ramp that uses less effort by traveling a grater distances

7. This a example Inclined plane.

8.  inclined plane connected to a medal rod or a post.

9.  A piece of medal or wood that has two inclined plane

10.  round shape connected to an axle that magnifies effort

11.  a simple machine that uses a rope and wheel to lift aload

12.  Simple Machine-any of six or more elementary mechanisms, as the lever, wheel and axle, pulley, screw, wedge, and inclined plane.

13.  Work- The effort needed to move a curtain distances

14.  Effort- The force to move something

15.  Mechanical advantage- reduced effort to increase distance

16.  Force- a moving motion
