### Honors Physics

#### What is inertia?

2: T 10/23, 5: M 10/22, 7: T 10/23Today, we'll look at the history of thoughts about motion since Aristotle. Remember that science is ever changing. We'll learn about Newton's first law - the law of inertia through conceptual examples. Homework: Find or make a video that demonstrates Newton's First Law. Creativity counts. Submit the link on Google Classroom by 10:00pm on Thursday, October 25th. Study for a brief quiz on Newton's First Law Tuesday, October 30th. |

#### How do you build a computer model of a real life situation?

2: M 10/15, 5: M 10/15, 7: T 10/162: W 10/17, 5: T 10/16, 7: W 10/17 Today, we'll continue to work on our computer models of the traffic signal timing. We'll have the Chromebook cart. You definitely need to be done with your mathematical model at this point. I will help those students who need help with the programming part of it. Make a really good plan for completing the task outside of class.Homework: Traffic signal project will be due to Google Classroom Sunday, October 21st. You will not be given any more time in class to work on this project. Don't forget to investigate a real-life intersection. This quiz will cover the physics of the lab rather than the computer or real-life intersection aspects. LAB QUIZ on Thursday, October 18th! |

#### How do you build a mathematical model of a real life situation?

2: Th 10/11, 5: W 10/10, 7: Th 10/112: F 10/12, 5: F 10/12, 7: F 10/12Today, we'll continue to work on our mathematical models of the traffic intersection that we started talking about last time. Homework: Traffic signal project will be due to Google Classroom Sunday, October 21st. You will be given one more day to work on this project in class. Please watch the following video if you are unfamiliar with using formulas in Google Sheets (or Excel). Even if you've used simple formulas in the past, you may want to browse the video to make sure you have seen some of the more common features. |

#### How can you engineer an intersection?

2: T 10/9, 5: T 10/9, 7: W 10/10Today, we'll start a new project where we'll be trying to engineer the timing of a traffic signal. You'll be designing your own flexible computer model. Then, you'll consider an actual real life intersection. Based on in-person observation and/or internet research, you'll decide priorities and parameters for the problem of determining the traffic signal timing. Then you'll input these parameters into your computer model to determine the final timing for the light. As part of the project, you'll be developing yourself in all of the areas of 21st Century Competencies - Effective Communicator, Collaborative Team Member, Creative & Practical Problem Solver, Flexible & Self-Directed Learner, Information Literate Researcher, and Globally Aware & Responsible Student/Citizen. Today, we'll introduce the project, and in your assigned groups, you'll start working on your computer model. We'll discuss possible inputs and outputs to your computer model as a class. You'll have time next class also to work together on the project. Presentation: Introduction to Traffic Safety Engineering ProjectHandout: Traffic Safety EngineeringHomework: Make some headway on your project. The project will be due on Sunday, October 21st, but don't procrastinate! |

#### How do your kinematics equations relate to graphs?

2: T 10/2, 5: T 10/2, 7: T 10/2You'll be able to use anything that is in (and attached to) your lab notebook and nothing else. No loose papers allowed. Open-lab-notebook QUIZ Today! After the quiz, we'll finish working on Unit 2 Worksheets page 1. I will be circulating to answer your question. Here you are learning to manipulate mathematical models (equations) as well as graphical models for kinematics. Then, we'll discuss how we can get your kinematics equations from your x vs. t and v vs. t graphs. (see presentation below.) If there's time, we'll do some more practice problems in small groups - Chapter 2 #20. 21. 33-36, 44, 48, 54-58, 77. Work on your collaborative team member skills. If you can do these problems and Unit 2 Worksheets page 1, you should be good for the test. Presentation: Deriving Kinematics Equations from GraphsHomework: We will start new material before then.

#### How do we deal with two different objects in one problem?

2: M 10/1, 5: F 9/28, 7: M 10/1Today, I'll take any questions on the "It's Your Lucky Day" Packet. Then, we'll talk about how to do #4 from "It's Your Lucky Day" Packet. We'll talk about the "equations of motion" (aka kinematic equations) that you have derived as part of this packet, and learn how to use equations of motion to solve problems with more than one object. Homework: Open-lab-notebook LAB QUIZ next class - Tuesday, October 2nd!!! No need to study, but you must understand everything you did in lab. Make sure you've answered the questions from last week. Finish "It's Your Lucky Day" Packet if you didn't finish it in class. Test on Kinematics Monday, October 8th. |
