### 🔴 2: T 11/21a, 🟡 4: M 11/20, 🔵7: M 11/20 - hula hoop problem (1)

Today, we'll look at the idea of rolling in a couple other ways, including imagining rolling WITH slipping. We'll investigate the motion of a hula hoop as it skates across the floor. The worksheet is due and will be collected.  In order to check your understanding of rolling with slipping problems, try 1980M3 a-c.

Moment of Inertia Lab Quiz - TODAY!

Today, we'll continue working on the Hula-Hoop Problem if you have not completed it.  In order to check your understanding of rolling with slipping problems, try 1980M3 a-cOtherwise, work on practice problems from old AP exams.  If you have any extra time, you can start watching homework videos below.

HomeworkHula-Hoop Problem due next class (physical on-paper submission).  Watch this video on rotational kinetic energy and check out the clarification image after the video:

### ❤️ 2: W 11/22*, 💛 4: M 11/27a, 💙7: T 11/21b - rotational kinetic energy (1)

Check-In: rotational kinetic energy.

Today, we'll work on the following problems on rotational kinetic energy:

Required:  2002M2, 1999M3, 1986M2, 1992M2 c, 1997M3 redo a-c using energy plus e
Enrichment: 1994M2, find more problems on AP Central

As you finish each problem, write at least one big take-away from the problem after each solution.  A take-away is something new you learned, something you need to remember, something you found surprising, etc.

Homework:  Rotational kinetic energy problems are due to ✏️ Google Classroom by Friday, December 2nd.  QUIZ on rotational dynamics and rolling with and without slipping on Wednesday, November 29th.

### 📕 2: M 11/27, 📒 4: M 11/27b, 📘7: W 11/22* - rotational kinetic energy (2)

Check-In: rotational kinetic energy.

Today, we'll finish problems from last time, and work on the following problems on rotational kinetic energy:

Required:  2002M2, 1999M3, 1986M2, 1992M2 c, 1997M3 redo a-c using energy plus e
