HP Cycle 3

🟢 5: F 9/16, 🔵 7: M 9/19 - position vs time graphs

Today, we'll start class by reviewing some of the things you learned last class, and we'll talk about notation in formulas.

Then, we'll together look at position vs. time graphs. We will look at the position vs. time graphs you created in lab last time to learn about features of position vs. time graphs. We will apply these understandings to a new graph and formally explore features.

Review Presentation: Intro to Kinematics

New Presentation: Ostrich & Cheetah Presentation

Handout: Ostrich & Cheetah WS, Graphic Analysis of Motion WS

Homework: Complete the first page ONLY of Graphic Analysis of Motion WS (position vs. time). ANSWER KEY.

🟩 5: M 9/19, 🟦 7: T 9/20 - velocity vs time graphs

Today, we'll finish learning how to read velocity vs. time graphs (Cheetah) together by completing the Ostrich & Cheetah Presentation. With any time remaining, you'll continue to work collaboratively on the rest of of Graphic Analysis of Motion WS.

Homework: Complete the second page of Graphic Analysis of Motion WS (velocity vs. time). ANSWER KEY. ❗ Mini-Assessment on Position vs. Time graphs on Wednesday, September 21st.

💚❗ 5: W 9/21, 💙❗ 7: W 9/21 - graphical analysis of motion review

❗ Mini-Assessment on Position vs. Time graphs TODAY!!!

After the assessment, we'll finish whatever we have not yet done with the Cheetah.

Then, in our lab groups, we'll continue the Graphic Analysis of Motion WS (velocity vs. time on page 2). ANSWER KEY. We'll review features of position vs. time graphs and velocity vs. time graphs, and you may ask questions if you don't understand. I will go over special aspects, especially about J-K-L and also H-I-J. We'll talk about some advanced concepts like how to find instantaneous velocity and acceleration when the graph is curved. We'll generate a list of phrases we can use to describe the motion given a graph.

Homework: Make a chart for yourself about the difference between analyzing displacement vs. time graphs and velocity vs. time graphs. In this chart, you should include answers to questions like: What does a 0 slope mean? What does it mean to cross the time axis? What does it mean if you have a positive slope? This will serve as a study guide for you for the upcoming check-in assessment. Upload a picture of your chart to ✏️Google Classroom. ❗ Assessment on all of graphical analysis of motion Wednesday, September 28th.
