HP Cycle 22

🟢 6: Th 1/21, 🔵❗ 8: F 1/22 inclined plane friction lab

Pd 8 - Quiz on ➕ Positive Physics unit 8: diagonal forces. (Rescheduled due to assembly)

Today, we'll investigate the coefficient of static friction on an inclined plane with a lab in ↩️ Pivot Interactives called "Friction: sliding on an inclined plane BCF."

Homework: Finish the lab above in ↩️ Pivot Interactives due Monday at 10pm.

🟩❗ 6: F 1/22, 🟦 8: M 1/25 inclined plane pulleys

Pd 6 - Quiz on ➕ Positive Physics unit 8: diagonal forces. (Rescheduled due to assembly)

Today, we'll 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. Then, we'll start the ➕ Positive Physics problems from next post.

Homework: Finish the ↩️ Pivot Interactives Friction lab due Monday at 10pm.

💚 6: T* 1/26, 💙 8: T* 1/26 ➕ Positive Physics inclines (2)

Today, we'll apply what you've learned about inclined planes to ➕ Positive Physics problems. Do the "work" problems from unit 9: inclined forces from the following sections:

• complete problems 3

• challenge

Only completion score counts, so try the problems till you get them right. Problems are due on Wednesday at 10pm. No late work will be accepted.

Homework: ➕ Positive Physics problems above due Wednesday at 10pm.

Optional Extra Practice: Table Top Pulley Problems, Solutions #3-4
