HP Cycle 4

🟢 8: W 9/24 - freefall intro

We'll start with an interactive discussion on acceleration, and later will split off into teams and use kinematics investigate and calculate a constant acceleration that is so familiar to us: "acceleration due to gravity" or "g". 

Presentation:  Calculating g Presentation

Homework:  Quiz on Kinematics Problem Solving next class - Thursday, September 25th on Wednesday, October 1st (does not include freefall)

Study Resource: Bear Acceleration Simulator 

This simulation should really help with wrapping your head around how an acceleration graph behaves. Play around with it to gain a better understanding of the kinematics. (Inspired from this video by Sungwon Cho)

🟩❗ 8: Th 9/25 - kinematics problems

Today, we'll revisit how to do #4 from  "It's Your Lucky Day" Packet, and learn how to use equations of motion to solve problems with more than one object.  

Next, you'll learn about some error analysis in your freefall lab.

Then, with any time remaining, we'll either finish the freefall lab investigation, or we'll collaboratively work on some kinematics problems from chapter 2 in your textbook:  

Chapter 2 Problems: 28, 32, 38, 60, 14, 12, 33, 39, 43, 73

Ask other students or me for help if you need it.  In writing out your solutions, be sure to practice including all the components of problem solving reviewed in class as this will help solidify good habits for the assessment next week:

1. Draw a picture or diagram or graph.

2. Pick a sign convention.

3. List your knowns and unknowns.

4. Write the formula you'll be using. (use your yellow sheet Equations of Motion Graphic Organizer)

5. Rearrange the formula with algebra so that your unknown is on the left side of the equals and all the knowns are on the right.  STAY IN VARIABLES!

6. Plug in numbers and box your answer.

Answer these problems in your classroom journal.  We'll have more time for these problems next time.

Homework:   Quiz on Kinematics Problem Solving on Wednesday, October 1st (does not include freefall).  Finish 📖 Mastering Physics Ch 2 problems by Tuesday, September 30th (new extended due date).  Because I reopened it, students who already finished it may do it again if you lost points anywhere.  

Recommended Additional Practice Problems:  deepen your understanding of Graphical Analysis Ch 2 #3, 4, 8, 18, 24, 19, 25, 20, 22, 36 (answer in Mastering Physics so you can see if you're right)

💚 8: F 9/26 - 📖 kinematics problem set (part 2)

Today, we'll continue to collaboratively work on some kinematics problems from chapter 2 in your textbook:
