Episode 1 - This is where we're at, this is where we are going.
This first video is me explaining the format of this years test. Going over the specifics and the example problems AP suggested we look at for clarification. It turned out to be a lot longer then I thought it would. I also had some technical difficulties getting it into a format that would post. I shot this one with my nice camera and microphone but it took longer to edit save and load then it did to film. So, might do the next one with just the iPad.
Before you watch it, you are going to want to have the following three docs available, which are posted here.
The Exam Specifics, Long answer and short answer examples.

Episode 2 - How Cups Roll
Episode 2 - How Cups Roll
This is a fun question about two differently arrange cups and how they roll down a ramp made of meter sticks.
Watch the beginning where I pose the question. Then take a few minutes to formulate your own solution.
I then offer three different explanations. Its a good place to start to get our brains thinking about Physics again. The solutions include rotational kinematics, force, and energy diagrams.
You should also be working through the unit 6 webassign the best you can. Email me the questions numbers you are struggling with and I'll make a video answering that question.
Episode 3 - Rolling motion & Energy
Episode 3 - Rolling motion & Energy
Happy Formal Friday. Today's video is on basic rolling motion. or what is called 'Pure' roll. Basically a normal rolling object that is not slipping or sliding as moves.
The next episode will be on rolling objects down hill and strings.
Episode 4 - How things roll downhill
Episode 4 - How things roll downhill
In this video we look at the dynamics of different object rolling down hill. Starting the the great Hoop versus Disk race of 2020. Then we look at how torque is applied to the different objects. Ending with how to determine which object will have the greatest acceleration.
My daughter also helps out a little. It was good to have a student tell me it doesn't make sense and to ask questions.
FRQ 1994 rolling uphill.pdfEpisode 5 - how things roll uphill
Episode 5 - how things roll uphill
This one looks at the dynamics of rolling uphill. Its a little counter intuitive with the way friction points. It also offers a good comparison type question, which I think the test will be focus on. There is also an old FRQ from 1994 that address the same concepts. So take a look at that question and the solution.
Episode 6 Angular Momentum
Episode 6 Angular Momentum
Watch Angular momentum with Walter Lewin
This is the basics. It’s kind of long. Watch at least the first 30 min.
Episode 7 Non-Intuitive Angular Momentum
Episode 7 Non-Intuitive Angular Momentum
Watch NON-Intuitive angular momentum with Walter Lewin.
This is the non-intuitive stuff on angular momentum. You can skip the first 14 min. which is on rolling motion.
Episode 8 Static Equilibrium
Episode 8 Static Equilibrium
Short lecture on Static equilibrium basics.
Episode 9 Falling sticks
Episode 9 Falling sticks
This is run demo with a stick, a lime, and a nail.
This is really helpful for understanding how different parts of the stick are tangentially accelerating at different rates, but still al have the same angular acceleration.

Mechanics Sample Long Question V2.pdfMechanics Sample Lab Question 2.pdfWedneday Mechanics Question 1.pdfWedneday Mechanics Question 2.pdfThere are a ton of videos lessons that the College board has posted.
There are also some timed practice exams you can take this week. These will have practice Long and Short answer question in the format you will see on Monday the 11th.
Monday they released the questions, which are posted here
Tuesday they went over the solutions. Unfortunately they only have a video of an instructor going over the solution and the rubric, not just a PDF of the rubric. Watch the video here.
Wednesday they put out another practice test. Posted here.
Thursday they again released a video rubric Watch it here.
Friday they did a video on exam tips.
