HP Cycle 19

🟢 6: M 1/4, 🔵 8: T 1/5 vector components

Today, we'll start a new unit by studying vectors in the two-dimensional plane. You will explore the topic with a 🤖 Gizmos: Vectors, while completing this packet in ✏️ Google Classroom which will guide your exploration.

Homework: Make sure the EL Gizmos - Vectors packet is complete.

🟩 6: T 1/5, 🟦 8: W 1/6 ➕ Positive Physics vector components

Today, we'll practice taking vector components in ➕ Positive Physics. We'll do "work" problems from unit 8: diagonal forces (11 problems total):

• free body diagram drawing

• trigonometry

Homework: These ➕ Positive Physics problems are due Wednesday, January 6th at 10pm. Only completion score counts, and no late work accepted. Next quiz on Thursday, January 7th ➕ Positive Physics unit 7: systems.

💚❗ 6: Th 1/7, 💙❗ 8: Th 1/7 static equilibrium

Quiz on ➕ Positive Physics (systems).

Today, we'll look at "static equilibrium" problems - where the forces are balanced. In these problems, we'll look at making ΣFx=0 and ΣFy=0, but some of the forces will be at angles. We'll look at an example that I call a "Y-tension problem."

Homework: If you have any questions about the Y-tension problem, you can review the problem below:
