Welcome to Physics 1 B 03 ! Physics 1 B 3 -summer Lecture 1 1

PHYSICS 1 B 3, S 07 - MECHANICS Dr. W. Okoń Office: ABB-237 A e-mail: okon@physics. mcmaster. ca Office Hours: M, R 2 -3 pm, T 3 -4 pm Course web page (all sections): http: //www. physics. mcmaster. ca/phys 1 b 03 Course web page (this section) http: //physwww. mcmaster. ca/~okon/1 b 03. html Physics 1 B 3 -summer Lecture 1 2

Grade Calculation: -Term work: 12. 5% of the final grade. 7. 5% will be for the CAPA problem sets, the rest will be for reading quizzes -Labs: 12. 5% of the final grade. -Two (2) Midterm tests: 30% of the final grade. -Final exam: 45% of the final grade. Physics 1 B 3 -summer Lecture 1 3

Components of the course: -Lectures: Students will read the relevant sections of the text before the lecture, and discuss topics among themselves from time to time during the lecture. -CAPA problems assigned ~ each week. -Labs: every week, 2 h long. Sign up (online – go to main course site) for a section if you don’t have one (if you signed up for the course after Sept 1) !!! Labs start next week, but… You must go to the lab this week (BSB-114) for about 20 min to learn Data Studio (any time b 4 3: 30 pm). Physics 1 B 3 -summer Lecture 1 4

Web. CT Login page: http: //webct. mcmaster. ca/ We are using the Web. CT system as the main source of information related to the course. Your term marks will be posted regularly. A “discussion area” allows you to seek help with assignment or other questions from other students in the course. Web. CT will be used for access to the CAPA assignment problems, so all students will need to use it. The Web. CT login page explains how to get your login account working. Start trying now! If you have a problem, it may require a few days to get it fixed by CIS. Physics 1 B 3 -summer Lecture 1 5

Homework Using CAPA Web page: http: //capa. physics. mcmaster. ca/ • There will be an assignment each week. Answers are entered into the computer. The CAPA system tells you immediately whether the answer is correct, and allows you to try again. You can log in and out many times without having to complete the entire assignment in one session. • You can access the CAPA assignments directly from Web. CT. • You should try to complete the CAPA assignments a day before the final deadline. You may use the student computer labs on campus. If you work from home, finish the assignments well in advance, to avoid being caught by internet malfunctions. • Read the CAPA help page before you start! (help on units etc…) Physics 1 B 3 -summer Lecture 1 8

Labs • You will need a lab manual and a black lab notebook with bound-in graph paper. The lab notebook will remain in the lab between sessions. • Labs begin with “Session 1: Kinematics in one Dimension”. Prepare for the lab by reading Appendix C in the Lab Manual (Introduction to Data Studio). This first lab period will begin with an introduction to the measuring equipment and Data Studio software. Check in Web. CT to see which lab section you are in. • You will also need to read the instructions for the lab itself (“Session 1”), and complete the pre-lab exercise to hand in when you arrive. Physics 1 B 3 -summer Lecture 1 9

Lectures • Introduce the important concepts and principles, with the aid of demonstrations. Examples with solutions. • Read the text as well (before the lecture); the lectures won’t include all the details. • Partial lecture slides will be posted on the web page or Web. CT before the lecture. The slides are not the whole lecture! Take notes as we work things out on the blackboard. • Lectures will include short “concept quizzes” after each main idea (not for marks, but for fun!? ). Physics 1 B 3 -summer Lecture 1 10

Example: Concept Quiz A 2000 -kg elevator starts from rest and moves upwards with a constant acceleration of 1. 0 m/s 2. The power required from the motor a) Increases with time, starting from zero b) Is large as soon as the elevator starts, then decreases with time c) Is constant after the elevator starts to move. Physics 1 B 3 -summer Lecture 1 11

Doing well in Physics 1 B 3 • Keep up with the course! Expect to spend 10 hours every week on the course, in addition to time in the lectures and labs. Come to the lectures. Read the text. Solve many, many problems. • Practice problems from the text will be listed each week. Try several of these. Think hard about them; don’t give up on the difficult ones. • Discuss questions and problems with other students. Explaining something helps you clarify your ideas. Physics 1 B 3 -summer Lecture 1 12

Homework • Read the course outline and find the course web page. Read everything… • Log in to Web. CT and find Physics 1 B 03. • Get the lab manual. If the bookstore is out of stock, put in an order right away. • Buy the text – you’ll find it useful for the next few years !!! Read the first two chapters of the text (review).
