### Honors Physics

#### What do you know already about forces?

6: F 10/18, 8: F 10/18Today, we'll start class by taking a pre-assessment for the next unit. Then with any time remaining, you'll work on your project. Homework: Project due on Sunday. Kinematics unit test on Tuesday, October 22nd. |

#### How well do you understand kinematics problems? How can you further investigate distracted driving?

6: W 10/16 (23 min class for PSAT) & Th 10/17, 8: T 10/15 & W 10/16 (23 min class for PSAT) You'll take the quiz and then grade yourself to make sure you understand what I'll be looking for on the unit test next week.Practice quiz Tuesday for pd 8 and Thursday for pd 6 with one kinematics problem. Homework: Work on your project. Next class (Friday), we'll be taking a pre-assessment for our next unit. The pre-assessment will take about half an hour. If you already know you will not be in class (for the pep-rally or for any other reason), then please make arrangement to take the pre-assessment ahead of time, perhaps during class or during your study hall period earlier in the week. Kinematics unit test on Tuesday, October 22nd. |

#### How can you further investigate distracted driving?

6: M 10/14, 8: M 10/14QUIZ Today on derivations of kinematic equations!With the rest of the period, you will work together on organizing your distracted driving project. I will consult with each group about how to take next steps in the project. Homework: Make some headway on your project. Practice quiz Tuesday for pd 8 and Thursdsay for pd 6 with one kinematics problem - quiz does not count for a grade and does not need to be made up. |

#### What else can you learn about distracted driving?

6: F 10/11, 8: Th 10/10Today, building off of what you already know from the deer project, we'll start a new project where you'll investigate more about the physics of distracted driving. We will follow the QFT protocol to generate questions about distracted driving. From the questions generated, you will be given a choice about what aspect of distracted driving you'd like to study more in depth. We will choose topics based on interest and relevance to the physics curriculum. Ultimately, we will find ways to inform the public about the dangers of and possible solutions to distracted driving. We'll be working on the project during class and outside of class. It will be due on Sunday, October 20th.Homework: Check Google Classroom for further instructions on the assignment. Make some headway on the research for your project over the weekend. The best studying you can do for this quiz is to look at your solutions to "It's Your Lucky Day" Packet.Quiz next class on kinematics formula derivations on Monday, October 14th. |

#### How do you solve kinematics problems?

6: M 10/7 & Th 10/10, 8: M 10/7 & T 10/8Today, we'll hone our skills in solving kinematics problems by working on these problems from Chapter 2 #20, 33-36, 44, 48, 54-58, 77. Remember to try to stay in variables until the last step of the problem! This is one of the skills you will be graded on. If you have already completed these problems, please find some more problems to practice from the end of Chapter 2. Solution guide is on my front desk in a pink binder.

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

6: Th 10/3 & F 10/4, 8: W 10/2 & Th 10/3Today, using your knowledge of the classic deer problem from last class, you'll use Google Sheets to program a computer model spreadsheet which will take inputs to the classic deer problem and output the result of whether or not the car hits the deer, and if it does hit, with what velocity. We'll also conduct experiments to measure your own distracted and not distracted reaction times. If there's time, I will introduce the harder extension project. With any time remaining, work on these problems from Chapter 2 #20, 33-36, 44, 48, 54-58, 77. Remember to try to stay in variables until the last step of the problem! This is one of the skills you will be graded on. Homework: No homework weekend. You should have already completed "It's Your Lucky Day" Packet and page 1 of Unit 2 Worksheets. ANSWERS.

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

6: T 10/1, 8: T 10/1Inclined Plane Lab Quiz TODAY!After the quiz, if we haven't done #4 from "It's Your Lucky Day" Packet, we'll start with that. 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. Then, we'll do the classic deer problem: "A car is traveling at a constant speed of 24 meters per second when all of a sudden the driver notices a deer 60 meters in front of him. Given that he has a reaction time of 1.2 seconds and that he can slow down at a rate of 6 meters per second squared, does he hit the deer? If so, at what speed does he hit the deer?" If there's any time remaining, we'll start our next project. Homework: Please watch the following video if you have not done so already. If you are already familiar with how to use formulas in Excel or Google Sheets, just skim the video to make sure you know how to do everything presented. |

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

6: F 9/27, 8: Th 9/26Today, 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 1st!!! 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. |

#### How can we solve problems using the formulas we derived from the definitions of average velocity and average acceleration?

6: Th 9/26, 8: W 9/25Today, we'll try to derive other kinematics formulas from the definition formulas for average velocity and average acceleration. After we derive these formulas, we can start using them for problems. There are several reasons why we're doing this exercise... (1) It's important to know where these formulas we're using come from. (2) It's important for you to know what I expect your solutions to look like for every problem - diagram, knowns & unknowns, accepted formula, algebraic manipulation to get an expression for the unknown, and finally a numeric answer. (3) It's good practice for all the algebra we'll be using in this class. We'll try to complete #1-3 on "It's Your Lucky Day" Packet during class. Then, if we didn't get to it last time, we'll discuss linearization of graphs and why we do it and what it accomplishes. Then, we'll talk about each of the five graphs in the Practice - Getting graphs from TTT data packet and how they were generated. We'll make connections to what we already know about graphic analysis of motion, what we did in lab, and what we learned from the "It's Your Lucky Day" Packet. We'll make sure we understand the process of linearizing graphs and what we gain by doing it. Homework: . Make sure you've completed #1-3 on "It's Your Lucky Day" Packet. Check your Solution to #2 below. Lab Quiz Tuesday |

#### How can you derive other kinematics formulas from definitions?

6: T 9/24, 8: T 9/24Today, I'll start by taking any questions you have about the lab. We've already learned about the equations that DEFINE average velocity and average acceleration. Today, we'll start to use our mathematical definitions to solve problems in "It's Your Lucky Day" Packet. In class, we'll do #1 together and then start #2 in your groups. If there's time, we'll discuss linearization of graphs and why we do it and what it accomplishes. Then, we'll talk about each of the five graphs in the Practice - Getting graphs from TTT data packet and how they were generated. We'll make connections to what we already know about graphic analysis of motion, what we did in lab, and what we learned from the "It's Your Lucky Day" Packet. We'll make sure we understand the process of linearizing graphs and what we gain by doing it. Handouts: "It's Your Lucky Day" PacketHomework: If you haven't finished anything with the lab, please make sure to do so. If you have not yet filled out the form with your angle and motion data, please do so before tonight at midnight! Look at the last post to see suggestions on what to add to your lab journal to make sure you are successful on the next lab assessment. Next Tuesday, October 2nd, you will take an open-lab-notebook LAB QUIZ!!! No need to study, but you must understand everything you did in lab. |
