Physics 102 – Physics for Engineers and Scientists II M/W Lec 3:05 pm to 4:30 pm and Lab 4:40 pm to 7:50 pm via Zoom

5 units, Section 20703, Prereq: Physics 101 and Coreq: Math 266 Calculus 2 Velveth Klee Ph.D. kleev@lattc.edu – 213-763-7321 – Help hours via zoom M, W 8-10am and by appt.

Welcome to Physics 102 – Discover the World Around You and Learn to Achieve Success How do bridges and railroads adjust to freezing winters or extreme heat? What provides power to buildings? What is happening in these systems at a microscopic level? What about the forces learned in Physics 101?

Extreme heat can cause railroad tracks to buckle. Metro is updating climate sensors to collect data that will inform design and decision making to reduce the negative effects of climate change on its riders.

Everyone who enrolls in this course is pursuing a career in the sciences or engineering. Physics can describe everything that we see around us, when we learn how to look. An airplane flying is a study in pressure and drag; a collision turns into a problem in momentum; a rainbow becomes an exciting show of refraction and dispersion; an earthquake illustrates shear forces and flexibility; bridge construction is about heat and expansion; a concert hall is the interplay of reflection and interference. In this class we will learn how to approach these and many more exciting problems relevant to your world and in life. With the fundamental knowledge base that we gain, we will learn how to apply concepts, and then use equations to solve physics problems. The answers to the questions above will be in our grasp!

Class Culture and the Learning Process The goal of this class is to learn physics. Everyone can learn physics. How we act as individuals and as a class will be key to accomplishing our goals successfully. You may struggle with understanding concepts. Not understanding something the first time does not mean failure. Einstein himself asked questions over and over while struggling to learn. Discoveries in physics are most often made by groups of scientists. Share ideas with others in order to move forward. Here are a few suggestions for success in learning:

→ Ask questions (of each other, of your instructor, or your text and resources), think about the answers, and ask more questions

→ Read all assignments carefully and complete to the best of your ability in a good faith way

→ Come to class ready to learn and be engaged in the class as a whole

→ Work together. Be the type of person you would like to turn to when you are in need of help.mailto:kleev@lattc.edu

Plan Your Approach to Learning Learning is a reinforcement process. Optimize the learning process by spending a consistent amount of time over several days on each lesson. The level of complexity of the material will increase slightly each day.

Before class During class After class but before next

class meeting In preparation for exam

Prepare for the lecture by reviewing notes,

reading text, attempting a few

problems, formulating some questions.

Attend lecture, concentrate intently,

take details notes, ask questions.

Review and annotate notes, reread text; work assigned problems, work

extra problems, meet with a study partner or study group to go over materials and problems

Review notes; review text rework problems,

meet with a study partner or study group to go over material and

problems.

Course Description and Learning Outcomes This course explores the fundamental principles and applications of thermodynamics (temperature, heat, engines, entropy and other topics), and electricity and magnetism (electric forces, electric fields, potential, magnetism, magnetic forces and fields, capacitance, resistance, inductance, DC and AC circuits and other topics) at the beginning calculus level of mathematics. The lab includes both quantitative and qualitative experiments that permit students to verify, illustrate, and deduce various laws of physics. By the end of this course, you will:

→ Analyze and solve problems related to physical systems, including Thermodynamics, Electrostatics, Electric and Magnetic Fields, Induction, Resistance, DC and AC circuits, and Maxwell’s Equations.

→ Conduct experiments involving the principles of physics, analyze data and report results.

Required Course Materials Text Book: Physics for Scientists and Engineers by Serway and Jewett 10th ed, Cengage Lab Manual: I will provide instructions and manuals

How the Class Grade Will Be Calculated Grade Assessments There are a range of assignments to assess your progress toward the goals of this course. We will discuss the details of assignments via Zoom and details will also be posted on our Canvas page. All assignments will be submitted as a PDF on Canvas.

Grade Calculation Letter Grade 25% Activities A – 100 to 90% 25% Labs B – 89.9% to 80% 50% Exams C – 79.9% to 70%

D – 69.9% to 60% F – 59.9% and below

Tips to Succeed in This Course → Attendance and participation are essential to your success in learning physics. Do your best to

attend live class on zoom, arrive on time and stay engaged. There may be days that you cannot attend lecture, that’s alright. Recordings will be available for you. Regular participation through submitting timely assignments and regular communication is required for this course. You may be dropped from class for failure to participate in a two-week period. If you decide to drop this course, please speak with me first so we may try to resolve your concerns.

→ Read and thoroughly understand assignments ahead of time. Make sure to read instructions and manuals. Start work on assignments early. Research shows that academic writers who write for 30- 45 min every day write significantly more and have more original ideas than those who write in large chunks (>1h) only when they are inspired (Boice 1990). Even if you aren’t done with the analysis for a lab, you can still write up what you have or work on the introduction or discussion section. If you don’t like something you write, don’t worry! You can revise (or delete or add) material.

→ Learn as a community. Your classmates are incredible resources. Often when you’re doing research on a topic, the best resources are other people. On the other hand, this resource is precious and limited. Don’t waste it by asking questions that can be answered with a quick look at a textbook or lab manual or a simple Google query.

Academic dishonesty policy: Violations of academic integrity of any type by a student provide grounds for disciplinary action by the instructor or college. Violations of academic integrity include, but are not limited to, the following actions: cheating on an exam, plagiarism, working together on an assignment, paper or project when the instructor has specifically stated students should not do so, submitting the same term paper to more than one instructor, or allowing another individual to assume one’s identity for the purpose of enhancing one’s grade. For more information on the Standards of Student Conduct refer to the college catalog available in hardcopy and online at www.lattc.edu.
