- What do you need? If you have taken PHYS101 last semester, you should
still have nearly everything you need, including the Turning Point polling system.
If you bought only 1-semester subscription (or if you didn't take PHYS101 in
Fall 2021) you will have to (re)subscribe for this semester following
THESE instructions. You don't
need a new book. The new Lab manual for PHYS102 is available on the companion
Lab Blackboard site.

- If you are new to this course, this is what you need: Our textbook ("Conceptual Physics" by Hewitt, ed. 12). Also, we will be using the TurningPoint polling system - see the Turning Point website and THESE instructions.
- I also recommend some additional books (from the library or even
to buy if you're interested): "Guesstimation" by Profs. Lawrence
Weinstein and John Adam (both at ODU), Princeton Press (a nice primer
on how to use rough quantitative estimations in everyday life); "How
Things Work" by Louis Bloomfield (UVa), Wiley; and "The Cartoon Guide
to Physics" by Gonick and Huffman, Harper Perennial. Also books by
Lawrence Krauss, Brian Greene etc....

- Feel free to send me email for
any questions you may have, or to set up an appointment outside of regular
office hours.

The purpose of this course is to give you a fundamental understanding how Physics can describe the world around us with a coherent body of concepts and models. We will develop some very abstract ideas (energy, heat, wave, matter) that have precise meanings (as opposed to the loose everyday meanings we associate with some of these words). We will also have to "unlearn" some of the "obvious" things we thought we knew about the physical world around us and how it works. Finally, to demonstrate the relationship between the abstract concepts and models and everyday phenomena or technical applications, we will have to study a variety of examples and observations and solve problems (as well as do lab experiments). It helps if you have some knowledge of math (high school algebra and geometry) and had some science courses in high school as well. Even more importantly, you should have some curiosity about science and how it can explain the natural world. Ask yourself:

- Have you ever wondered what it would feel like if you were "weightless"? What "weight" actually means? How you can tell from the time it takes a stone to drop to the bottom of a well how deep that well is? What you would see if you had "microscopic eyes"? Why (and if) energy is never "lost"? How we can understand the way atoms, nuclei and elementary particles interact? How the Universe really began?
- If I tell you that the square of the orbit time of a planet is
proportional to the orbit radius cubed (T
^{2}proportional to R^{3}), could you tell me how much orbit time would increase if orbit radius increases fourfold? (Elementary algebra - the answer is "8 times")

- If I tell you the vertical and horizontal components of a vector,
can you tell me its length? Its direction? (Elementary Geometry)

If you tend to faint at the sight of any mathematical equation, this course may not come easy. If you have too heavy a course load already and cannot commit substantial time and effort to this course, you may be disappointed by the outcome (I recommend to reserve AT LEAST 10 hours every week for this course). Note that you only have until the beginning of the second week of classes to withdraw with full tuition refund, and only one more week to withdraw with 1/2 tuition refund. It pays (literally) to figure out right away whether or not you plan to continue the course.

- Typically, HW problems are keyed towards new "tools" covered in
the
chapter
they are attached to. If a problem in Chapter 7 asks you to calculate
the
speed of an object after falling in Earth's gravitational field,
chances
are you should use "Energy" to solve
this
problem (which is the chapter title). Also, look at the "Summary of
Terms" and the "Review Questions" at the end of each chapter to find
relevant information.

- If you don't have enough time to thoroughly study the book, at least make sure you go over several of the examples and "check yourself" questions for each chapter. Try to "think ahead", by covering up the "solution" and first trying your own hand at it. If you are really pressed for time (HW deadline), try to find examples that look similar to the problem at hand and see which tools are applied how (and why).
- Never wait until the last minute before the deadline to submit
your answers - there could be a last-minute technical problem and there
won't be any extensions! In fact, you should ALWAYS plan to submit your
solutions on the day before the hard deadline.

- For extra practice,
you should do additional problems/exercises (and the "Review
Questions") in the book or click on "practice" in WebAssign. Try to get
as far
as possible on your own,
and then ask me or a Learning Center staffer (or a fellow student) for
help where you need it. I also strongly encourage you to try out some
of the "projects" in the book and as many of the animations in
the web links below as you can.

- Some of you will have the companion book "Practicing Physics" which has many nice practice questions with solutions (plus a list of solutions to all odd-numbered exercises and problems in the book). Study these!
- I can not do more than a sample problem every now and then in class. However, make sure you benefit at least from the ones I do by interrupting me if I'm doing something you can't follow. I'd rather have you understand one worked-out example than getting confused by a torrent of several running by too quickly.
- Doing problems is not easy, but you will get better at it with practice. Unfortunately, there is no shortcut or a simple collection of "recipies" - you need to understand the underlying concepts to solve a problem.
- Often it helps to work with other people and/or in the Learning Center. Bouncing ideas and questions of each other may clear things up - and there's often someone experienced around to ask if you really get stuck. For your convenience, you can submit your HW answers to Blackboard from the computers in the Learning Center.
- As you can see, this class DOES require several extra hours of work every week outside of the class room!

And now some other "good advice":

- When you study the book, focus on the summaries at the end of each chapter and the "Review Questions". Make sure you understand the terms listed (read the relevant part of the chapter in the book if in doubt) and find at least one example in the text that illustrates each concept. Do all the "check yourself" problems in the text by covering up the solution first, then check! Make use of any additional study material that came with the book, or go to the book website.
- The companion book "Practicing Physics is a perfect study guide -
but you have to keep up with each topic as it is treated in class. Fill
in the blanks and then check yourself!

- Go over past homework problems. Often an exam problem is just a
variation
of a previous homework problem. Try to remember (or reconstruct)
**which**concepts where used and how you could tell those were the relevant ones. Look at my solutions!

- Take a look at the formula sheet. It contains equations and formulae that you might need during the exam. Try to recollect where and how each of these equations were introduced, and what situations they apply to (again, look for examples in the book).
- Remember, midterm exams will cover the chapters in the book treated in class up to the day before the exam, beginning with the first chapter not covered in the previous midterm (for the second and third). However, some "background knowledge" from all of 101 and 102 may be needed to answer a given question. The final exam covers all material from 102 equally.
