1 AP PHYSICS C Mechanics - SUMMER ASSIGNMENT FOR Dear Student: The AP physics course you have signed up for is designed to prepare you for a superior performance on the AP test. To complete material in the textbook and still have fun, exciting and educational labs and associated lab reports we must pass quickly through dimensional analysis other basic topics. I have included copies of chapter 1 of your text book and chapter 2 of a non-calculus-based text book, and a link to a useful web site to warn you up for the beginning of fall semester. No textbook is needed to complete the assignment but you are expected to have a text book on the first day of class. This summer assignment is due on Thursday August 9 th, 2018 at the beginning of class. There will be a quiz on that first day of class. The text book has answers to some problems in chapter 1 and Chapter 2. The summer assignment is worth 100 homework points and is due in on the first day, written on a separate paper, with clear headings and your name. I will not accept summer assignment after the beginning of the lesson. Have it ready to hand in. Note if insufficient work is shown because it was all done on your calculator, your calculator will be credited with half the points for the summer assignment. Sincerely Mr D. Darling Dana.Darling@jserra.org The summer assignment is listed below: DUE DATE PREPARATION ASSIGNMENT Turned in on Go to the following web site: A. Take 1 page of notes on each the first day video. Use the print screen

2 of class 1/AP1_Physics.html View the following algebra based Physic 1 videos: Introduction What Is Physics? Math Review Significant Figures Scientific Notation Metric System Vectors and Scalars Mechanics,Kinematics o Defining Motion o Graphing Motion o Kinematic Equations o Free Fall Know go to the following web site for AP Physics C: View the following videos: Math Review 1. Dot Product (Scalar Product) 2. Cross Product (Vector Product) option on your computer to capture images that you want to include. B. Second page: The videos have some example problems. Write down each question and each of your answers. Include any calculations for math problems. Note the web site is an excellent resource and you should use it throughout the year. This is your first test in fully reading directions! Now read the box to the right on what you need to turn in. Turned in on the first day of class I have copied chapter 1 and 2 for you to use during the summer. You must have the textbook by the first day in school. Chapter 2 is from a non-calculus based text book. 1 st read chapter 1, outline the chapter and do questions starting on page 15: questions 5, 8, Your outlines should include key words with definitions, equations, units; you may use diagrams etc. from the book. These are your notes; you are expected to outline each chapter during the course. When answering questions show all your

3 Turned in on the first day of class 10, 12, 13, 15, 16, 18, 21, 26, 31, 32, 35, 40, 46, 53, 63 & nd read chapter 2, outline the chapter and do questions on pages 58 and 59 Multiple choice questions 1 to 20. Page 59 conceptual questions 1,6, 9, 12, and 16. Page 60 to 66, questions 3,7,11,23,31,33,37,39,41. Do the following activity using this web site ns-base.html Then click on The Moving Man work. Write neatly and clearly. Show steps. Box the final answer. Make a note of questions you are not sure about; ask about these questions in class. Complete the work sheet, Moving Man - Velocity vs. Time Graphs Which you will find after chapter 2, below.

62 Moving Man - Velocity vs. Time Graphs Background Remember graphs are not just an evil thing your teacher makes you create, they are a means of communication. Graphs are a way of communicating by using pictures and since a picture is worth a thousand words knowing how to make and interpret graphs will save you a lot of writing. Learning Goals The students will: Develop a general knowledge of Velocity vs. Time graphs and Distance vs. Time graphs o What graphs of a person standing still would look like o What graphs of a person moving away from an observer at a constant speed would look like. o What graphs of a person moving towards an observer at a constant speed would look like. o How differences in speed appear on the graphs Activity & Simulation Instructions- The 0m point where the moving man is located is an arbitrary point and all distance measurements will be made from that point. The positive and negative values on the position graph represent the direction the man moves from the 0m point. To close the acceleration graphs the students need to click on this symbol, located in the upper right hand corner of the acceleration graph Descriptive vocabulary to use in their description of a graph. For example; Description of Samples of descriptive phrases Direction Moving from to Moving away from observer Speed Standing still Moving slow Moving fast o Procedure Do the following activity using this web site Then click on The Moving Man Screen 1 Moving towards observer 1. Getting started. After The Moving Man is open leave the position graph and the velocity graph open but close the acceleration graph. Your screen should look like screen 1.

63 Moving Man - Velocity vs. Time Graphs 2. Making observations. By either clicking on the man or the slider cause the man to move back and forth and observe what shows up on the graphs. Using the axis provided below make sketches of Distance vs. Time and Velocity vs. Time graphs for the actions described next to each axis. A man moving from 0 to 10 at a slow steady pace. Distance (m) Time (s) Velocity (m/s) Time (s) A man moving from 0 to 10 at a fast pace. Distance (m) Time (s) Velocity (m/s) Time (s) A man standing still at 4 m Distance (m) Time (s) Velocity (m/s) Time (s)

64 A man moving from 0 to 10 at a fast pace the moving back to 0 at a slow pace. Moving Man - Velocity vs. Time Graphs Distance (m) Time (s) Velocity (m/s) Time (s) A man moving from 0 to -10 at a fast pace the moving back to 0 at a slow pace. Distance (m) Time (s) Velocity (m/s) Time (s) A man moving from 10 to 0 at a fast pace. Distance (m) Time (s) Velocity (m/s) Time (s) Apply what you learned. Look at the Distance vs. Time graph below and for the different parts of the graph that are marked by the dotted lines make the corresponding Velocity vs. Time graph directly below each part. Distance Time 10 Velocity 5 0 Time Open the acceleration time graph your screen should look like below:

65 Moving Man - Velocity vs. Time Graphs

66 Moving Man - Velocity vs. Time Graphs Now type the following: Position -10m Velocity 0m/s acceleration 1m/s 2 Press play and pause the animation when he reaches the house Sketch the graphs you see below:

67 Moving Man - Velocity vs. Time Graphs Now type the following: Position 0m Velocity 8m/s acceleration -4m/s 2 Press play and pause the animation when he returns to his original position. Sketch the graphs you see below for the first 4 seconds: Describe the motion of the man: His velocity is positive /negative at first, his velocity increase/decrease the acceleration is positive/negative, when he reaches the house his velocity , then his velocity becomes positive/negative, his velocity increases/decreases and become more/less, his acceleration is positive /negative.

68 Moving Man - Velocity vs. Time Graphs Now type the following: Position 10m Velocity -10m/s acceleration 3m/s 2 Press play and pause the animation when he returns to the house Describe the motion of the man:
