C&S Chapters 1-10, miscellaneous other
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.

3-100 point tests |
Feb 1, Mar 1, April 5 |
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, 10:30 12:30 |
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. |
Due Monday, April 26 at 12:00 |
Magazine article reviews must contain your name, class,
source, date and a brief synopsis of each article. 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. |
|
OTQ's - 100 pts |
Daily |
- 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, 2010), 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.
