HP Cycle 25

🟢 6: M 2/8, 🔵 8: T 2/9 ➕ Positive Physics projectile motion problems (1)

Today, we'll continue the Projectile Motion Presentation by starting to look at projectiles launched at an angle. We'll look at a special case of a projectile that is caught at the same height as it was launched.

Then, we'll be practicing what you have learned previously about projectile motion. Do ➕ Positive Physics "work" problems from unit 4: projectile motion:

• preparation problems

• complete problems 1

• complete problems 2

Homework: Above ➕ Positive Physics unit 4 problems due Sunday at 10pm. Only completion score will count, so keep trying the problems until you get them correct. No late work will be accepted.

Optional Extra Practice: Projectile Motion CompuSheets page 1 (Solutions). Chapter 3 #44, 45, 46, 49, 50, 54 (Solutions)

🟩 6: T 2/9, 🟦 8: W 2/10 ➕ Positive Physics projectile motion problems (2)

Today, we'll finish the Projectile Motion Presentation by continuing to look at projectiles launched at an angle with more general projectile motion problems.

Then, we'll continue practicing additional projectile motion problems. Do ➕ Positive Physics "work" problems from unit 4: projectile motion:

• complete problems 3

• challenge

Homework: ALL ➕ Positive Physics unit 4 problems due Sunday at 10pm. Only completion score will count, so keep trying the problems until you get them correct. No late work will be accepted. Quiz on Projectile Motion next Wednesday.

Optional Extra Practice: Chapter 3 #58, 60, 61, 65 (Solutions) and Projectile Motion CompuSheets page 2 (Solutions)

If you want more support with projectiles launched at an angle, you may watch the rest of Dan Fullerton's video on projectile motion (minute 11 until the end) and more practice problems below. If you like his videos, search for him on YouTube ("aplusphysics") for future topics. His "Regents Physics" series would be an appropriate level for this class.

💚 6: Th* 2/11, 💙 8: Th* 2/11 universal gravitation

Today, we'll talk about Newton's Law of Gravitation. We'll first look at Gravitational Interactions. Then, we'll introduce Newton's Gravitational Constant and do some calculations. Do ➕ Positive Physics "work" problems from unit 11: universal gravitation:

• gravitational force problems

Homework: ➕ Positive Physics unit 11 problems due Tuesday at 10pm. Only completion score will count, so keep trying the problems until you get them correct. No late work will be accepted. Quiz on ➕ Positive Physics Projectile Motion next Wednesday. For additional support on Newton's Law of Gravitation, watch the following video:
