  II. Course Goals*:

     The objective of this course is to familiarize students with the principles of physics as basis for their continuation of studies in Science and Medical profession. At work sites, the graduates often need to work with equipment that work by the virtue of physics principles. Examples are traction equipment, X-ray machines, sonogram, blood pressure measurement devices, etc. The examples and problems selected for the course give the students the necessary knowledge and skills to read and analyze scientific data with proper understanding of the units involved and the type of physical quantity measured. The first few chapters lay down the foundation that is absolutely necessary to understand the physical quantities that appear in later chapters and are often seen on equipment used in medicine or industry. On this basis, after finishing this course, students will be able to:

 

A

explain Metric and American units and systems and perform various conversions between the two, (The gauges at work sites often use both types of units),(V.1 & V.3)

B

Describe the motion of a body and calculate the necessary parameters by using equations of motion in a practical situation,(V.1 & V.4)

C

Analyze force-motion relations in a practical situation ,(V.1 & V.4)

D

calculate the work done by a force as well as energy calculations and conversion to heat (calories),(V.1 & V.4)

E

explain different forms of energy and their conversion to each other as well as the Principle of Conservation of Energy in practical situations at work sites,(V.1, V.2, V.3,& V.4)

F

apply the laws of conservation of energy and momentum, (V.2, V.3,& V.4)

G

calculate the parameters involved in the motion of a rotating object such as particle separators (centrifugal separating devices),(V.2 & V.4)

H

apply the laws of fluid pressure and density to measure the necessary parameters in a practical situation at work, (V.1 & V.3)

I

make temperature measurements in different scales and convert and use them for heat and energy calculations with or without phase change,(V.3)

J

apply the equations for thermal expansion of solids, liquids, and gases, (V.3)

K

Describe oscillatory motion by measuring wavelength, amplitude, and the phase of motion of mechanical waves such as sound, (V.1 & V.3)

L

apply the knowledge of sound parameters such as frequency, wavelength, and in interpreting the signals on measurement devices in sonography and ultrasound, (V.3)

M

apply the conditions of static equilibrium to find the forces acting on an object in a given situation, (V.1 & V.3) and

N

use the concept of torque of a force to analyze the static equilibrium of a rigid body. (V.3)

Roman numerals after course goals reference the stipulated outcomes of Natural Science programs under General Education Goals.

  IV.  Evaluation:

 Students are primarily evaluated on the basis of test/quiz type assessments and homework as outlined on the syllabus and supplement distributed by the instructor.

 

A

The following formula is used to evaluate the course grade:

Course Grade = (0.75)x(Theory Grade) + (0.25)x(Lab Grade)

 

B

Theory Grade = 0.80(Tests + Quizzes + H.W. ) + 0.20(Comprehensive Final)

Tests count (80%), quizzes (10%), and homework (10%).  The number of tests may vary from 5 to 7.  The percentages given for tests, quizzes, and homework may vary depending on the instructor.

 

 

C

Laboratory Grade = (the sum of reports grades) / (the number of the reports).

10 experiments* are designed for the course. Each experiment requires a report that must be at least spell-checked. Procedures for a standard lab report will be given by your instructor.  To avoid a ZERO Laboratory Grade, at least 6 reports must be turned in.  No late lab report(s) will be accepted and there are No Lab Make-ups.

D

Site Visits: The necessary site visits will be announced as the arrangements are made. Evaluation will be based on of attendance as well as the visit report.

E

Grading Scale:   (91-100: A),  (87-91: B+),  ( 81-87 : B),  (77-81: C+),  (70-77:C), and (60-70: D)

 V. Policies:

 A. Attendance Policy: Pellissippi State expects students to attend all scheduled in­structional activities. As a minimum, students in all courses (excluding distance learning courses) must be present for at least 75 percent of their scheduled class and laboratory meetings in order to receive credit for the course. Individual departments/programs/disciplines, with the approval of the vice president of the Learning Division, may have requirements that are more stringent. In very specific circumstances, an appeal of the policy may be addressed to the head of the department in which the course was taken. If further action is warranted, the appeal may be addressed to the vice president of the Learning Division.

 B. Academic Dishonesty:  Academic misconduct committed either directly or indirectly by an indi­vidual or group is subject to disciplinary action. Prohibited activities include but are not limited to the following practices:

• Cheating, including but not limited to unauthorized assistance from material, people, or devices when taking a test, quiz, or examination; writing papers or reports; solving problems; or completing academic assignments.

• Plagiarism, including but not limited to paraphrasing, summariz­ing, or directly quoting published or unpublished work of another person, including online or computerized services, without proper documentation of the original source.

• Purchasing or otherwise obtaining prewritten essays, research papers, or materials prepared by another person or agency that sells term papers or other academic materials to be presented as one’s own work.

• Taking an exam for another student.

• Providing others with information and/or answers regarding exams, quizzes, homework or other classroom assignments unless explicitly authorized by the instructor.

• Any of the above occurring within the Web or distance learning environment.

 C. ACCOMMODATIONS FOR DISABILITIES

Students who need accommodations because of a disability, have emergency medical information to share, or need special arrangements in case the building must be evacuated should inform the instructor immediately, privately after class or in her/his office.  Students must present a current accommodation plan from a staff member in Services for Students with Disabilities (SSWD) in order to receive accommodations in this course.  SSWD may be contacted by going to Goins 127, 132, 134, 135, or 131 or by phone: 694-6429 (Voice/TTY) or 539-7153.  More information is available at www.pstcc.edu/departments/swd/ 

 Emergency College Closing: If for any reason the college has to close for any number of days, it is your responsibility to study and follow the syllabus as if you are attending classes.  You should frequently check your email and follow the instructions given by your instructor as how and when tests will be given.  For laboratory experiments, our existing physics applets on our NBS Website will be used.  You will perform online experiments and email your reports.

ATTENTION FINANCIAL AID AND/OR HOPE SCHOLARSHIP RECIPIENTS:

Maintaining continuous attendance in your classes is very important.  If you are considering dropping or withdrawing from a course, please check with the Financial Aid Office before doing so.  Dropping or withdrawing from a class can adversely affect your financial aid and/or lottery eligibility.  

 D. Final Exam:  Final Exam must be taken during the Final Exam Week.  No early Final Exam will be given.

 E. Lab Reports: No late lab report will be accepted and there are No Lab Make-ups
