Here are the lecture notes from the last class!

About the Final

The final will be entirely multiple choice, although some of the problems will really be written problems "in disguise" as discussed in today's lecture. Somewhere between 33% and 50% of the exam will cover the recent material, post in-term exam 3. The remainder will cover the entire semester's earlier material. The "new" material startes with chapter 13, section 6, and ends at the end of Chapter 17 but skipping chapter 15. Chapter 18 in particular will not be included, since I did not cover it at all in lecture.

Thermodynamics

Much of chapter 16 involves definitions and conversion among units, such as between units of moles and mass. While I expect you to know some of the definitions (such as that for a mole) I do not expect you to remember all of the various conversion factors --they will be provided on the exam. Given the conversion constants you should know when and how to convert from one unumbernit to another, for example psi to pascal for pressure. Particularly important among units and quantities is aboslute temperature, and the Kelvin scale of temperature. The other thing you should be able to do is to convert between of atoms and mass of atoms. There are three concepts/topics you should know well from chapter 16. You should know the ideal gas law backwards and forwards. You need to be able to appreciate the meaning and use of the ideal gas constant R and the other quantities of the system. You should also be familiar, be able to create and use, a P-V diagram. Finally, you should know and understand the constant state-variable processes such as constant pressure, constant volume, and constant temperature, for an ideal gas (and adiabatic, but that is introduced in chapter 17).

 

Rolling down an incline.

Several students asked me about the inclined plane problem involving a sphere, hoop, and cylinder. Here you will find a complete treatment of the problem.

What will be covered on the third in-term exam?

The exam will cover the material in Chapter 9 through the Chapter 13, section 13.5 end.

For chapter 13, be sure to know how to solve the problems of a) similar to example 13.13 of a mass and pulley with a non-slipping string causing the pulley to turn as the mass falls and b) an object rolling down an inclined plane without slipping. The exam will include at least one problem like these. (Note, the second problem can be treated using conservation of energy, but rotational energy conservation is not covered by the exam and therefore is not needed to address any exam problem). Also be able to calculate the moment of inertia of a simple object, and know how to use the parallel axis theorem.

For chapter 9 and 10, you will need to know how to treat collisions and be able to recognize whether a given collision is elastic or inelastic. Inelastic collisions must be solved with conservation of momentum alone, while elastic collisions are solved using both energy and momentum conservation. The prototypical problem involves two colliding objects having different masses moving in two dimensions. However, this prototypical problem does not address impluses. Hooke's law is introduced in Chapter 10 as well, together with spring (eleastic) potential energy.

Notice that several types of problems that were solved by Newton's laws were solved again and often more simply using energy conservation. To this end I noticed several problems had trouble with problems involving ramps (meaning gravitational potential energy) together with springs. Also in the context of Chapter 11 you will want to understand work and power. Of the exam topics, I think it is easiest to go down the wrong road with power especially when friction is involved. Identifying *which* force is doing the work will often seem tricky. I recommend problem 11.66, 11.67 and similar problems for practice.

For Chapter 12 on Newton's theory of gravity, the in-class problem of geosynchronous orbit is a good excersise. If you know how to do that one, you should also be able to work though related problems, such as the speed of a satellite in circular orbit, and the gravitational acceleration of a given mass for a given distance from the mass. While Kepler's third law is a consequence of Newton's theory, it is worth working through a separate set of end-of-chapter problems to understand it.

GOOD LUCK!

NO CALCULATORS ON EXAMS? WHY?

Many students are concerned about having to carry out arithmetic without a calculator during the exams. Click one the announcement at left, or here, to read more.

First Recitation

On Thursday August 31 you will have your first recitation section meeting. Check out the Recitation Information for room information and a map for how to get there.

Welcome to Physics 1110!

Physics 1110 is a calculus-based introduction to the physical laws that governs how, when, and why objects move. This course has two instructors: For the most part, Lectures will be given by Professor Dana Z. Anderson, while behind the scenes Professor Edward Kinney keeps the recitations, tutorials, homeworks, and other aspects of the course running smoothly.

Getting Started

We recommend that you begin by carrying out four tasks. First you have not already done so, purchase a Remote Response Device ("clicker") from the bookstore and register it so that you will earn course credit for your attendance and participation in Lecture. Second, take the online survey. Actually, you are not required to do the survey, but it does earn you some relatively easy class participation points. More importantly, these surveys are used to assess the effective ness of the course and to guide us towards making it better. You will be asked to take another survey at the end of the semester. Note that you responses to the survey do not affect your grade. Don't be concerned if you are unable to answer some of the questions --we do not expect you to be able to answer everything correctly. Begin by reading through the general information pages, which provide general information about the course, contact information, expectations on you, the student, our grading policy, and general information on course and University policies on the Honor Code, disabilities, and so forth. Third, read through the General Information document for the course. There you will find out all kinds of useful things, like our grading policy, rules, contact information and what not. Fourth, within those pages you will also find instructions for logging onto the "Mastering Physics" website, the online interactive homework system used in conjunction with this class.
