PHYSICS: Wow! Do you realize what we just did? We finished the chapter! Well, we’ll add this small lecture on simple machines from chapter 7 to the chapter 5 test – but we’re done! Did you remember this stuff on simple machines from your physical science days?
I don’t think you’ll have any trouble with efficiency and mechanical advantage problems. How do you think the efficiencies of machines compare? Could you design a method to test that? You don’t need no stinkin’ lab sheets! Do you?
