PURPOSE: Physics is the study of the properties of matter and energy. In Physics 213, our focus was particles. You learned how to describe and influence the motion of particles. You also learned about  fundamental quantities and conservation principles. Now, we will build on your knowledge of physics. In this course, our focus will be fields. We'll study fields and their effects on particles by using a very well known and understood example -- the electro-magnetic field. During the first block, we will study the electric field and the work done by the field as it acts on an electric charge, while  during the second block we will study the magnetic field. The third block, we'll study physical waves, and then tie all three blocks  together by studying electromagnetic waves. In the third block, we will also look at the curious phenomena of interference and  diffraction of light and we will have a brief introduction to modern physics. Along the way, we'll try to highlight the relevance and usefulness of the material to your future and every day living.   If we have time, we'll squeeze in some thermodynamics.

 

Electricity

Micro-electricity:  Atomic level interaction of charged particles, (mostly electrons), in electric fields.

 

Macro-electricity:  Effects of micro-electricity, namely;

Coulombs Law: 

Ohm's law:  V = IR

Bio-Savart Law:  dB = km (Ids x ) / r2

Faraday's Law:  The emf (e) induced in a circuit is directly proportional to the time rate of change of the magnetic flux thru the circuit.

Lenz's Law:  The polarity of the induced emf is such that it tends to produce a current that will  create a magnetic flux to oppose the change in magnetic flux through the loop.

 

Electronics:  Applications of Macro-electricity

 

Civilization is measured by the degree to which we control energy.

Planting and harvesting is corraling energy from the sun.

Harnessing a horse is control and utilization of the horse's energy.

Damming up rivers is harnessing gravitational potential energy.

Heat engines harness kinetic energy of gas molecules.

Batteries harness chemical energy, and are the first step in controlling  the energy of electrons.

As we climb higher on the technological ladder, it becomes more and more apparent that each advance in  technology depends on an increased understanding and control of the behavior of electrons.

 

Mechnical forces are actually manifestations of the repulsive forces between electrons, as is also chemical interactions, and current flow in a conductor.

 

Light, (electro-magnetic waves, or photons) is created by the acceleration of electrons.

Even gravity is somehow connected to the motion of electrons.  Scientists have found that the unfettered motion of electrons in superconductors somehow affects gravity.

 

The progress of mankind will be determined by the degree to which we learn to understand and control electrons.

 

This course is primarily the study of macro-electricity, which is roughly equivalent to tying one end of a  rope to a horse, the other end to an object we want to move, and then trying to scare the horse into running in the direction we wish the object to be moved, and cutting the rope when the object has been moved far enough.

 

Micro-electricity would be equivalent to learning to speak horse and simply telling the horse what you'd like it to do.

 

Throughout we will try to blend in enough micro-electricity to hopefully ignite enough interest in you to inspire you to delve ever more deeply into this key to our technological future.

 

EVALUATION:

Date

Discussion

3-100 point tests

Feb 1, 29, April 2

No make up tests will be given.  A missed test will be replaced by 1/2 of your final exam score.

1-200 point Final Exam

May 5, 1-3

Final will be comprehensive.

8 to 12 - 15 point experiments

Varies,  approximately one a week

Lab write-ups due dates are Wednesday   of the next week after the lab is done.  Late labs cost 2 points each weekday late.  Redo's are due 1 week after returned to you before being considered late. You must make up missed labs to avoid an incomplete in the course.  Make up labs will not be the same as regular class labs.

1- 35 point Project or 7 5 point magazine article reviews.

Those doing science team get 65 points (30 pts Bonus)

Due Friday, April 25 at 12:00

Magazine article reviews must contain your name, class, source, date and a brief synopsis of each article.

Due dates for projects will depend upon the individual projects.  Due dates will be whatever is mutually agreed upon by the instructor and the project group.  Some form of written description of your physics project and a progress report  is due on April 27.  You  will be charged 5 points for each day late.  None accepted after final exam.

 

Science Team Journals must be kept up to date this semester.

Class Acts - 100 pts

TBA

 

Weekly homework assignments  100 pts total.

Due on the following Mon

Total value will be 100 points.  approximately 7 points each assignment. To receive credit, the assignment must have your name course number, and homework number. None accepted late.

Returned homework will be kept in your notebook!

OTQ's - 100 pts

Daily

 


- Bonus Points 40 pts. max.

 

- Letters to politicians, or editors expressing your opinion about issues regarding the physical universe in which we live. 1 point each, 15 points maximum.  You may send copies of the same letter to a maximum of 5 different people.  You may turn in letters in stamped, addressed envelopes, along with a copy for the instructor, on the same day project reports are due.

 

- Assisting math or physics students 5pts. per hour, 20 pts. max.  (Must be done in the Library or Physics Lab verified in writing by either an instructor or librarian.)

 

- Occasional hand in bonus problems ( bonus questions on tests do not count toward this max)5 pts. each, 30 pt. max.

- Book report, 10 pts. (Book must be approved by instructor prior to reading, and reports are due on April 24)

 

GRADES: 

 

The above total, excluding bonus points,will roughly be 1000 points, and your accumulative total will be divided by the total to calculate your final average.

 

  90 - 100 = A, 80 - 89 = B, 70 - 79 = C, 60 - 69 = D, 0 - 59 = F

 

NOTES: 

 

l.  Final percentage will be rounded UP, i.e., a final percent of 79.00000001 will be rounded up to 80.

2.  You should keep all returned papers.  You should also keep track of the ratio (your accumulative total)/(The accumulative total possible to date) as the quarter progresses.  If this ratio is below 70 at midterm (Mar. 1, 2002), you should come for a conference with the instructor to discuss what each of us can do to retrieve you from doom.
Note: Unless otherwise specified, problems assigned this week are due on monday of the next week.  Experiments assigned  this week are due on Wednesday of the next week.
