### About the course

PHY2049 is an introduction to general physics, Part 2. Topics covered include:

- electric charge as fundamental property of matter;
- electrostatics (Coulomb Law, electric field, electric field potential);
- EMF; currents; resistors; heat dissipated by resistors;
- capacitors;
- circuits with batteries, resistors, and capacitors;
- magnetic field due to moving charges, magnetic field force on moving charges;
- electric field induced by changing magnetic field;
- magnetic field induced by changing electric field;
- inductors;
- alternating EMF; circuits with alternating EMF, inductors, capacitors, and resistors;
- Maxwell equations;
- electromagnetic waves;
- optics (reflection, refraction, mirrors, lenses);
- basic optical instruments (magnifying glass, correction glasses, telescope, microscope);
- interference and diffraction phenomena with electromagnetic waves.

Our goal at all times is to help you understand the basic physical principles so that you could develop a deeper vision of the real world around you. In addition to providing the basic theoretical underpinnings to the subject, we use many examples, "concept problems", physical and virtual demonstrations. We also show many examples of everyday tools and advanced instruments that utilize these principles.

### Prerequisites

**PHY2048 (Physics 1 with calculus)**

The course will rely heavily on the following level of math (see textbook Appendix E for details). If you are not competent at this level you should take the appropriate refresher course(s) before taking this class; otherwise, you are bound to fail.

- Algebra
- Trigonometry
- Analytic Geometry
- Vectors
- Differential and integral calculus

### Required material

The following material must be acquired not later than by the end of the first week of classes:

### Required work and points toward your final grade

The course work includes:

- reading the text for the assigned material,
- attending lecture (during lectures, we will administer quick HITT-based quizzes);
- doing the weekly homework;
- attending discussion section (and taking the discussion section quizzes);
- and taking the exams;

### Effective strategies for learning physics

From interviewing students we have found that the A to B+ students have better habits and spend more time on this course than B and C students. In particular, they rarely miss class, do all the recommended homework problems and more, read ahead and study the material for several hours a week (not just before exams). Developing good habits at the start of the semester, before things get busy and you fall behind, will help you succeed.

A large fraction of your study time should be devoted to problem solving,
which is *essential* to learning and cannot be replaced by mere
listening and reading.

The following strategies will help you to do well in the course:

The best strategy for success is to stay up to date with the readings and homework. In particular, solving problems will improve your performance on exams and quizzes far better than memorizing formulas or cramming. A good rule of thumb is that you should be spending about 6-9 hours per week on the material outside of class.**Keep up with the course.**. We cannot stress enough the importance of coming to class. Frequent class skipping contributes strongly to poor student performance. However, attending classes and doing something else at the same time like reading papers, browsing internet, texting/emailing, doing homework, etc. is a waste of your time.**Attend lectures and discussions regularly**: even though you may not understand the chapter material, advance reading "primes" your brain to be receptive to the material when it is discussed in lecture or discussion.**Read ahead before lecture**: as you learn new concepts, your questions cannot possibly be wrong or stupid and are very likely to be widely shared.**Be proactive and ask questions**Working out the weekly problem sets (plus extra problems as needed) is the most important element of the course. It is absolutely critical that you invest YOUR PERSONAL HONEST EFFORT into solving problems by yourself---it is the only way to learn the main concepts in physics and prepare yourself for discussion session quizzes and exams. The following pattern of studies never fails:**Homework and extra problems.**- Before proceeding with homework, review the summary at the end of the chapter. You should understand the exact meaning of each formula (variables and constants entering the formula and in which situations the formula is applicable) without having to re-read the synopsis.
- Attempt to work out each problem
*yourself*and*do not give up easily*. Making a good neat drawing is a-must; make a drawing even if there is a good picture in the textbook. Make a list of all variables given to you. As you put down all this on a paper, you help your brain to see what actually happens in the problem on hand. - Always work out problems symbolically all the way to the end; only then, when you have the final expression for the answer, plug in numerical values for the variables. This will help you to keep track of what you are doing. Before plugging in numbers, check that the answer has the right units.
- If you get stuck (which is
*absolutely normal as your learn!*), do not hesitate to consult with your friends and certainly take advantage of office hours. After you have understood the conceptual flow leading to the solution, attempt to solve the same problem in a day or two without looking in your notes. - For each problem that you had to ask for help, find a similar problem in the text book or past exams and attempt to solve it yourself. This is the key for making sure that you mastered the concepts!
- If you see that you can solve problems yourself, but it still takes more than 5-10 min per problem, keep working out extra problems; remember: you have about 5 min per problem on the exams.
- Never ever start from looking at someone's solutions without having get stuck on the problem first.
- After each exam, always make sure you review and fully understand how to solve ALL problems of the exam you just took.

. If you don't understand something, ask someone during office hours. Office hours are spread across many hours of the week for your convenience. There is also a Tutoring Center with a number of people and resources for students in Physics courses, and a student organization, Tau Beta Pi, which provides help on the homework and reviews before exams.**Do use office hours**-

### Honor Code

**The UF Honor Code**applies to all aspects of this course. It is required that you report any possible infractions to your instructor immediately.

### Students with disabilities

Students with disabilities requesting accommodations should first register with the Disability Resource Center (352-392-8565, www.dso.ufl.edu/drc/) by providing appropriate documentation. Once registered, students will receive an accommodation letter which must be presented to the instructor when requesting accommodation. Students with disabilities should follow this procedure as early as possible in the semester.
