HP Cycle 10

🟢 8: F 10/31 - Newton's 3rd Law & 2-block systems

Quiz on Newton's 2nd Law problems (including elevator problems) Monday, November 3rd!   QUIZ CANCELED! 

Lesson: Today we will be introducing Newton's third law, addressing misconceptions, and learning what the law really means in different situations.

Objective: Learn how to draw free body diagrams and identify Newton's Third Law Force pairs!

Homework Half Sheet: Identifying correct force pairs from free body diagrams 

Extra resources: Here are some juicy Newton's third law videos in case you need extra practice or conceptual help with grasping what's going on.  

🟩❗8: M 11/3 - 📖 2-block system problems

Lesson: Newton's Third Law: Real-world Application and Problem Solving with two body systems

Today we will be going deep into problem solving with the knowledge of how third law force pairs work, and how, most motion we think of, for example, jet propulsion, from a third law force pair. We will problem solve these scenarios in nature, technology, sports, and engineering, with actual numbers and values.

We will also be addressing Rizzbert vs Skibidalbert's once and for all.

Objective: Learn how to solve for forces and accelerations from a Newton's Third Law force pairing with proper notation and diagrams.

Activity: Physics Loot Boxes (Duos version)

Homework:  Finish your problem that you started in class: All problems, hints & Solutions (Google doc)

Assessment of all of Newton's Laws in 1-D on Tuesday, November 11th Wednesday, November 12th (last assessment in 1st marking period).

💚 8: T 11/4 - Newton's third law & pulleys

Lesson: Newton's Third Law: Pulley introduction, Problem Solving

Today, as Eihiko alluded to, we will be looking at systems that are connected via a rope on a pulley, aka "Atwood machine". How does a rope exert force on two connected objects? What do the ΣF statements look like with Tension? How do we problem solve for a pulley problem?

Homework:  Pulley half sheet homework due to Google Classroom tonight at 10pm.  Assessment of all of Newton's Laws in 1-D on Tuesday, November 12th (last assessment in 1st marking period).
