W 12/6

🟢 5: F 12/1 - ↩️ Pivot - friction on inclined plane 

Remediation test for those who are eligible today.

Today, we'll work on a ↩️ Pivot lab called "Friction: sliding on an inclined plane."  

Homework↩️ Pivot lab "Friction: sliding on an inclined plane" is due Monday, December 4th at 10pm.  Remember that no late work is accepted in ↩️ Pivot;  labs auto-submit at the due date and time.  Also, remember 📖 Mastering Physics "Ch 5 - inclined plane problems" due Sunday, December 3rd at 10pm.  Quiz on inclined planes Wednesday, December 6th!  

OPTIONAL ENRICHMENT (for those thinking of taking AT Physics especially):

Try some even harder pulley problems.  If you need some ideas on how to approach these problems, you can watch the video below, but don't forget to write a ΣF statement in the y-direction to get your normal force for the mass on the incline.  

Optional Enrichment Extra Credit: 📖 Mastering Physics "Ch 5 - inclined plane pulley problems": #MQ22, MC30, 63, 83.  These problems are due on Monday, December 18th at 10pm if you choose to do them.  No late work will be accepted, no exceptions.

🟩 5: M 12/4 - friction and vector forces

Today, we'll look at one other kind of problem - we pull or push a block at an angle.  We'll see that when we do this, the normal force is NOT equal to the force of gravity!  We'll try to finish Friction & Vector Forces during class.  Watch the video...

Homework:  Finish Friction & Vector Forces (SOLUTIONS) and upload your solution to ✏️ Google Classroom by Tuesday, December 5th at 10pm.  Quiz on inclined planes next class - Wednesday, December 6th!  

💚❗ 5: W 12/6 - projectile motion intro

Quiz on inclined planes TODAY!

Today, we’ll start looking at projectile motion. We’ll start by looking at projectiles launched horizontally. We’ll discover that projectiles move at constant velocity in the horizontal direction where there’s no net external force, whereas they move with constant acceleration (g) in the vertical direction where the external force is due to gravity. (Air resistance is ignored.) In order to solve projectile motion problems, we often split the problem into x- and y-components, and then combine x & y with time. 

Presentation: Projectile Motion PowerPoint

HomeworkQuiz on projectile motion on Tuesday, December 12th.  For more support, watch the following two videos by Dan Fullerton.  They are both on projectile motion.  Watch only the first 11 minutes of the first video, and watch the entire second video.  The second video contains examples which you need to work through alongside Mr. Fullerton.
