Required: "Fundamentals of Physics" by Halliday, Resnick, and Walker, 9th Edition. 2. Required: "MasteringPhysics Access Code (see below). 3. Required: "TurningPoint Clicker (see below). 4. Required: "APSC 111 Course Manual" available on Moodle website (Sample problems for review of material) 5. Required: Complete the online Mechanics Background quiz…once at the start of the course, once at the end of the course. You are not marked on the answers, but get 2% credit for participation. This helps with the accreditation of your program. 6. Lecture notes: will be posted online at the Moodle site. (under instructors name) APSC 111 Intro/Vectors Page 1.5 Online Assignments • Due each Sunday at 10 PM • First one due Sunday September 19th (vectors) → go to www.masteringphysics.com, • Resister for the online assignments using access code (Use access code purchased at Bookstore. This is a better rate than what is available online… negotiated for this class.) • e-mail address: ajn01@queensu.ca • student number: 7654321 • Course ID: Important to get format right !! APSC111MGB • Should start with “Introduction to Mastering Physics” (this will teach you how to enter answers properly) APSC 111 Intro/Vectors Page 1.6 EXAMS • No books or notes for examinations! • Formula sheet will be provided in advance • Best recipe for success is to make sure you understand the conceptual ideas, and practice, practice, practice to make sure you can apply concepts. (Tutorials and assignments also give you practice … that is their main function) APSC 111 Intro/Vectors Page 1.7 Mid-term Exam I • Wednesday, October 13th, 7:00-9:00 PM (typically this is in multiple choice format, and covers the material covered to date…within reason) Mid-term Exam II • Wednesday, November 10th, 7:00-9:00 PM (typically this is a number of problems on all the material covered to date…within reason) Dates are tentative…! APSC 111 Intro/Vectors Page 1.8 Tutorials • Tutorials start in week 3; Questions will be assigned on Moodle site. • Typically, at most 3 of the questions will be the topic of each tutorial. The remaining questions should be regarded as homework. Tutorial questions are NOT marked, but you are encouraged to attempt all problems. • Solutions to each week's tutorial problems will be posted on Moodle over the weekend following the tutorial. • The most benefit from the tutorials is obtained when students attempt the questions before hand, at least at a rudimentary level. • Please bring list of questions to the tutorial, plus formula sheet, and questions for the TA. APSC 111 Intro/Vectors Page 1.9 Tutorial sections: • please attend your assigned section! • If there is room you can occasionally attend a different section (same problems covered) APSC 111 Intro/Vectors Page 1.10 “Clickers” • We are using TurningPoint Clickers. These are the same clickers as for your calculus course. You only need to buy one. • NOT iClickers (which are used more in the life sciences.) • Clickers will be used to provide feedback on understanding of key concepts (as a group, not for individual students) • You are NOT graded on clicker answers! • You are graded on participation. • For full marks must respond to most questions in at least 80% of lectures • See Moodle site for instructions on how to register your clicker for APSC111 APSC 111 Intro/Vectors Page 1.11 We will use channel 41 APSC 111 Intro/Vectors Page 1.12 Where would you find this famous potato? 75% 1. 2. 3. 4.

Your mark on this quiz does not affect your course mark, but you will receive 2% for participation. Information will be provided soon…we will announce when it is open initially (and over what period). Watch Moodle for information. APSC 111 Intro/Vectors Page 1.14 Course Outline 1. Measurement & Vectors 2. Kinematics 3. Dynamics 4. Work and Energy 5. Linear Momentum and collisions 6. Rotational Dynamics 7. Static Equilibrium (Chapt 1, 3) (Chapt 4, 5) (Chapt 5, 6) (Chapt 7,8) (Chapt 9) (~2 lectures) (~4-5 lectures) (~6 lectures) (~6 lectures) (~6 lectures) (Chapt 10,11) (~7 lectures) (Chapt 12) (~4 lectures) Oscillations & Waves no longer covered in APSC 111 … moved into APSC 112 Rotational Dynamics now covered in APSC 111 … moved out of APSC 112 Be careful when looking at old exams ! APSC 111 Intro/Vectors Page 1.15 ACADEMIC INTEGRITY (see www.queensu.ca/academicintegrity) APSC 111 Intro/Vectors Page 1.16 Vectors Please read Chapter 1 and 2 for very basic material we assume you are familiar with…(units, descriptions of displacement, velocity, acceleration etc.) This lecture covers the material of chapter 3 sections 3.1 to 3.8. Not everything can be done in class, and this is expected to be a bit of a review. Please read those sections. APSC 111 Intro/Vectors Page 1.17 Vectors and Scalars: • Addition of Vectors—Graphical Methods • Subtraction of Vectors, and Multiplication of a Vector by a Scalar • Adding Vectors by Components • Unit Vectors • Scalar and Vector products APSC 111 Intro/Vectors Page 1.18 Vectors and Scalars A vector has magnitude as well as direction. Some vector quantities: displacement, velocity, force, momentum A scalar has only a magnitude. Some scalar quantities: mass, time, temperature Vector quantity specified as v (magnitude is v = | v |) APSC 111 Intro/Vectors Page 1.19 Addition of Vectors—Graphical Methods For vectors in one dimension, simple addition and subtraction are all that is needed. You do need to be careful about the signs, as the figure indicates. APSC 111 Intro/Vectors Page 1.20 Addition of Vectors—Graphical Methods If the motion is in two dimensions, the situation is somewhat more complicated. Here, the actual travel paths are at right angles to one another; we can find the displacement by using the Pythagorean Theorem. APSC 111 Intro/Vectors Page 1.21
