Physics 12-2-11 Simple Machines

PHYSICS: Happy Friday! Here’s the lecture from Friday on simple machines. We’ll add this little bit of chapter 7 to the chapter 5 test. At the very beginning of the vodcast, I say something completely wrong, and although we correct it later, let me do so again here. The two categories of simple machines are inclined planes and levers. Got it? Sorry about that!

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? Lab Monday and test Wednesday. Have a great weekend! đŸ™‚
