We will cover Chapters 1 through 17 of the text. You will learn about linear and circular motion, gravitational and frictional forces, rotational motion, work and energy, momentum, fluids, thermal physics, and wave motion.

There are several possible reasons to take physics. One is to open students' eyes to the wonders of the physical world around them. Another is to train them to analyze what they see by developing simple models of that part of the world in which they are interested. This last reason is called problem solving, which is a key ingredient in learning physics. Finally, the experience in this course will help in making the student a more informed individual, which can come in handy when basic issues in science become political issues.

What is physics? Physics is the most basic science. It touches every part of your daily life at every moment. It governs the heaters and air conditioners, which allow us to live in comfortable surroundings. It is responsible for the light used to read this syllabus, or to make it possible for cars to bring you to class. Without physics energy could not be transported in DNA molecules to allow biological systems to develop, grow and reproduce.

The word physics has its roots in the Latin word physica and the Greek word physis, which mean nature. Physics is the study of the underlying principles that govern the behavior of the world around us. It is important that everyone have some understanding of the physical world in our technological society.

"What do we mean by understanding something? We can imagine that this complicated array of moving things which constitutes the world is something like a great chess game being played by the gods, and we are observers of the game. We do not know what the rules of the game are; all we are allowed to do is watch the playing. Of course, if we watch long enough, we may eventually catch on to a few of the rules. The rules of the game are what we mean by fundamental physics. Even if we know every rule, however, we might not be able to understand why a particular move is made in the game, merely because it is too complicated and our minds are limited. If you play chess you must know that it is easy to learn all the rules, and yet it is often hard to select the best move or to understand why a player moves as he does. So it is in nature, only much more so; but we may be able to at least to find all the rules. Actually, we do not have all the rules now. (Every once in a while something like castling is going on that we still do not understand.) Aside from not knowing all of the rules, what we really can explain in terms of those rules is very limited, because almost all situations are so enormously complicated that we cannot follow the plays of the game using the rules, much less tell what is going to happen next. We must, therefore, limit ourselves to the more basic question of the rules of the game. If we know the rules, we consider that we understand the world."

To many students physics is difficult. Of course, this is true of any subject, which is not understood. The point is that physics can be understood through logic and objectivity. Physics is a subject, which builds on itself. Unfortunately, students must learn the basics, before they can venture to the more interesting applications. So, the subject may at first appear to be boring and not very relevant.

Another problem students face is that the study of physics requires new terminology and a new way of thinking. One cannot hope to learn physics the night before the exam. Therefore, in this course you will be expected to do homework assignments on a regular basis. In fact, you should spend several hours a day doing physics. [You should spend at least six hours per week on physics outside of class.]

A final discouragement to studying physics is the use of mathematics. Mathematics is a tool for expressing the observed relationships between physical quantities. Physics is not mathematics. The principles of physics can be stated without mathematics, but the mathematical equations are more compact and can be used to predict the values of unknown quantities from known ones.

In a basic course, such as this one, we will practice using this tool by solving simple word problems. We will do this in the homework, in the lectures and in the exams. The key to doing word problems is the approach that one takes. In the following is a set of steps, which you should always follow to be successful:

The goal of physics is to describe the maximum number of phenomena in our universe in terms of the minimum number of general principles. Also, these principles should be as simple as possible. Therefore, as you read the text and follow the lectures, you should get into the habit of identifying these principles. A suggested practice is as follows:

In order to become familiar with these and other recent developments in physics, there will be periodic bonus questions handed out for extra credit. You will be required to answer these in essay form to receive credit. Only neat work will count! Bonus points will be added to earned homework points.

Course Requirements:

All exams will be closed book and no formulae will be included. There will be no makeup exams without prior permission. Graphing calculators are not permitted for the exams.

The final exam will be cumulative, covering all  seventeen chapters, and is to be given 11:30 am -2:30 pm on  December 6th. The tentative exam schedule is given below.

Your grade will be based on the following information:

Topics To Be Covered:

Kinematics Displacement, velocity, acceleration, free fall, projectile motion.

Linear Dynamics Newton's Laws of Motion, forces, gravitation, friction, work, energy, power, momentum, collisions and conservation laws.

Rotational Dynamics Circular motion, angular velocity, angular acceleration, centripetal force, moment of inertia, torque, angular momentum, and rotational energy.

Matter in Bulk/Fluids Elasticity, simple harmonic motion, springs, pendula, density, pressure, buoyancy, fluid flow.

Thermodynamics Temperature, thermal expansion, phase changes, molecular motion, kinetic theory, gas laws, laws of thermodynamics, entropy.

Doing and thinking about physics is important in learning the material. You should do all multiple choice and as many of the problems a possible. The problems below will be collected and graded using WileyPLUS. The full assignment list is posted online. (These are subject to change.)
