 Extended Closure: 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.


II. Course Objectives:


     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:



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)


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


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


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


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)


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


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


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


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


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


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


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


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


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


Roman numerals after course objectives reference goals of the university parallel programs.












III. Instructional Processes:


       Students will:


learn in a cooperative mode by working in small groups with other students and exchanging ideas within each group (or sometimes collectively) while being coached by the instructor who provides assistance when needed, (Active Learning Strategy),


learn by being a problem solver rather than being lectured, (Active Learning Strategy),


explore and seek the solutions to the given problems that measures his/her level of accomplishment, (Active Learning Strategy),


visit industry sites or will be visited by a person from industry who applies the concepts being learned at his/her work site, (Transitional Strategy),


gradually be given higher- and higher-level problems to promote his/her critical thinking ability, (Active Learning Strategy),


search for the solution to the assigned projects by examining the available software and resources. (Transitional Strategy),


get engaged in learning processes such as projects, mentoring, apprenticeships, and/or research activities as time allows, (Transitional Strategy),  and


use computers with appropriate software during class or lab as a boost to the learning process (Technology Literacy Outcome).


IV. Expectations for Student Performance:*

solve temperature and heat problems with or without phase change, (I),


solve problems involving heat effect and thermal expansion in solids, fluids, and gases (J),


solve problems in oscillatory motion in order to find the parameters involved (K and L),

Letters after performance expectations reference the course objectives listed above.




V.  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.



The following formula is used to evaluate the course grade:

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


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.




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.



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.


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


VI. Policies:


Attendance: College Policy mandates that a student be present for at least 75% of the scheduled class and lab meetings in order to receive credit for the course.

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

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

Students with Disabilities:  If you need accommodations because of a disability, if you have emergency medical information to share, or if you need special arrangements in case the building must be evacuated, please inform me immediately.  Please see me privately after class or in my 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. Services for Students with Disabilities may be contacted by going to Goins 125, 127 or 131,or Alexander 105 or by phone: 694-6751(Voice/TDY), 539-7153, 539-7091 or 539-7249.
