HP Cycle 24

🟢 6: T 2/2, 🔵❗ 8: W 2/3 boat problems

Pd 8 - Quiz today on ➕ Positive Physics: unit 9 - inclined forces.

Today, we'll finish the "boat problems" in Boat Problems PowerPoint.

Chapter 3 #68, 71-74, 78, 80, 82. Solutions.

Homework: Finish the above problems.

🟩❗ 6: W 2/3, 🟦 8: Th* 2/4 airplane problems

Pd 6 - Quiz today on ➕ Positive Physics: unit 9 - inclined forces.

Today, we'll finish the last two "airplane problems" in Boat Problems PowerPoint. In doing so, we'll review how to add vectors which are not at right angles together, both graphically and mathematically with components.

💚 6: F 2/5, 💙 8: F 2/5 projectile motion intro

Today, we’ll start looking at projectile motion. We’ll start by looking at projectiles launched horizontally. We’ll discover that projectiles move at constant velocity in the horizontal direction where there’s no net external force, whereas they move with constant acceleration (g) in the vertical direction where the external force is due to gravity. (Air resistance is ignored.) In order to solve projectile motion problems, we often split the problem into x- and y-components, and then combine x & y with time.

Presentation: Projectile Motion PowerPoint

Homework: QUIZ on relative motion (boat & airplane problems) on Tuesday.

For more support, watch the following two videos by Dan Fullerton. They are both on projectile motion. Watch only the first 11 minutes of the first video, and watch the entire second video. The second video contains examples which you need to work through alongside Mr. Fullerton.
