❗Quiz on center of mass, rotational kinematics, and moment of inertia TODAY!   

If there's any time remaining, please go back to working on problems from Chapter 10 on calculating moment of inertia:

Support: 42
Required: 36, 38, 40, 43, G50, G42, G46
Enrichment: G49, G51

Homework:  ❗Quiz on Massive Pulley Problems and Massive Pulley Lab on Friday, October 30th!  

🟥 2: W 10/28, 🟨 4: T 10/27, 🟦 5: T 10/27 - massive pulley problems (2)

Today, we'll continue working through the "massive pulley problems" that we started last time.  We'll do these problems from Chapter 10:

Support: 49, 50
Required:  51, 53, 54, 55, 56, 69, 71, 98
Enrichment:  57, 87

Homework:  Finish these massive pulley problems by tonight.  ❗Quiz on Massive Pulley Problems and Massive Pulley Lab on Friday, October 30th!  

❤️ 2: Th 10/29 lab, 💛 4: W 10/28 lab, 💙 5: Th 10/29 lab - ✏️ moment of inertia lab

Today, you'll focus on collaboratively carrying out an investigation to experimentally find the moment of inertia of the PVC-T.  You may have to perform your experiment several times to engineer the best possible set-up to get good data.  Your goal is to get a great graph or two.  Screen shot your graphs and paste them into your Google Slides presentation (on Google Classroom) so that we can work with the graphs next time.

You may not take data unless the following are approved by me:

1. general procedure

2. how you plan to use time data (how are you going to use ALL the data?)

3. prediction of graph outputs

Remember, you may not ignore the torque of friction in this lab.

Lab Safety:  If the PVC-T is spinning, it could hurt if it hits you.  Please make to be aware when you are walking around the room that you do not walk into a spinning piece of equipment.  Make sure to follow all other directions about equipment.

Homework:  In your Google Slides presentation in ✏️ Google Classroom, make sure you have diagrams of set-ups (can be a photograph), free body diagrams, and prediction(s) for the graphs.  ❗Quiz on Massive Pulley Problems and Massive Pulley Lab next class - Friday, October 30th!  ❗Moment of Inertia Lab Quiz - Monday, November 9th.
