Enduring Understandings

 * Simple machines can multiply the force OR the speed of an effort, but only at the expense of the other.
 * Compound machines can be assembled from simple components, but sometimes with a loss of efficiency.

Prior Learning (from S8 Anchors)
S8.C.3.1 Describe the effect of multiple forces on the movement, speed, or direction of an object.
 * S8.C.3.1.1 Describe forces acting on objects (e.g., friction, gravity, balanced versus unbalanced).
 * S8.C.3.1.2 Distinguish between kinetic and potential energy.
 * S8.C.3.1.3 Explain that mechanical advantage helps to do work (physics) by either changing a force or changing the direction of the applied force (e.g., simple machines, hydraulic systems).
