HP Cycle 20
1/9 - 1/12
🟢 5: M 1/9, 🔵 7: T 1/10 - 📖 Mastering 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 📖 Mastering Physics Chapter 3 problems "Ch 3 Projectile Problem Set 1": #28, 32, 60, 63, 66, 79, 31, 33, 57, 64.
Homework: Above 📖 Mastering Physics problems due Wednesday at 10pm.
Optional Extra Practice: Projectile Motion CompuSheets page 1 (Solutions).
The following videos may help with one of the problems in 📖 Mastering Physics:
🟩 5: T 1/10, 🟦 7: W 1/11 - 📖 Mastering 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. We'll do Example 4 together.
Then, we'll continue practicing additional projectile motion problems. Do 📖 Mastering Physics Chapter 3 problems "Ch 3 Projectile Problems Set 2": 35, 36, 62, 67, 69, 73.
Homework: 📖 Mastering Physics above due Thursday at 10pm. Unit Test on Dynamics in 2-Dimensions on Tuesday, January 17th!
Optional Extra Practice: 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.
Additionally, you can watch these more advanced videos on projectiles launched at angles and landing at a different height:
This video by Michel van Biezen is very similar to the problem that we did in class.
This is an even more complex problem from Flipping Physics. Try this on your own for more of a challenge.
💚 5: Th 1/12, 💙 7: Th 1/12 - dynamics in 2-D practice
Today, finish your projectile motion problem set and study for your unit 4 assessment. Consider doing optional extra practice posted previously or do additional textbook problems. Remember that every assessment is cumulative, so be prepared to ask anything from Chapters 1-5 in your textbook (except sections 3.7, 3.8, or 5.6). The focus however will be on problems in two dimensions (vectors, trig).
Homework: 📖 Mastering Physics second projectile motion set due Thursday at 10pm. Unit Test on Dynamics in Two-Dimensions on Tuesday, January 17th!
