### 🟢 5: M 11/27 - 📖 Mastering Physics dynamics in 2-D

Today, we'll practice static equilibrium problems 📖 Mastering Physics "Ch 5 - dynamics in 2-D problems": #MC25, 1, 2, 4, 7, 10, 11, 34, 75

Homework📖 Mastering Physics "Ch 5 - dynamics in 2-D problems" due Tuesday, November 28th at 10pm.  Y-tension lab due in your lab notebook tomorrow, Tuesday, November 28th in class.  Quiz on static equilibrium & 2-D vector forces on Thursday, November 30th.

### 🟩 5: T 11/28 -  inclined planes

Today, we’ll look at how we can apply what we know about vectors in two dimensions to inclined plane problems. The key to inclined plane problems is picking a coordinate system that makes sense.  We must shift our thinking from a traditional horizontal-vertical coordinate system to a slanted coordinate system.   We'll extend the discussion to link to our inclined plane lab that we performed a long time ago.  We'll talk about what factors affect the motion of an object on an inclined plane theoretically and in real life.

If you missed today's lecture or you need to review some, watch the following video.

HomeworkQuiz on static equilibrium & 2-D vector forces next class - Thursday, November 30th.  Review your notes and write down any questions you may have about solving inclined plane problems.

### 💚❗ 5: Th 11/30 - 📖 Mastering Physics inclined plane problems

Quiz on static equilibrium & 2-D vector forces TODAY.

Today, we'll apply what you've learned about inclined planes to 📖 Mastering Physics "Ch 5 - inclined plane problems": 24, 25, 28*, 30*, 65, 77,  (* need to look at coefficient of friction table) and optionally for a challenge #MQ22, MC30, 63, 83 which require you to put multiple ideas together.  If you are having any trouble, re-watch my Inclined Plane video.

Homework:  📖 Mastering Physics "Ch 5 - inclined plane problems" due Sunday, December 3rd at 10pm.  Quiz on inclined planes Wednesday, December 6th!

Optional Extra PracticeDo page 6 of the Newton's Second Law packet (skip 3c).   You may check Solutions to Inclined Plane Problems, but try them on your own first!   Also, in 📖 Mastering Physics "Ch 5 - inclined plane problems", do challenge problems #MQ22, MC30, 63, 83 which require you to put multiple ideas together.
