Physics I [Phys 161]                                    Spring 2004 Assignment #4 Reading, Vocabulary & Objectives A. Availability and Due Dates Assignment #4 is available Friday, February 13, 2004.  The target date for its successful completion is Monday, February 23, 2004.  In any event, all problems from Assignment #4 must be successfully completed and turned in by 5:00 pm on Wednesday, February 25, 2004.  If this requirement is not met, the student will not be allowed to take Exam 2, to be given in class on Friday, February 27, 2004.   B. Reading As preparation for completing the problems in Assignment #4, read Chapter 5 in Serway & Jewett. C. Vocabulary As part of Assignment #4, the following vocabulary words must be understood and memorized in addition to those already listed on Assignments 1-3: Dynamics, Centrifugal, Fictitious Force, Equilibrium, Inertial Reference Frame (IRF), Non-Inertial Reference Frame (NIRF), Weight, Inertial Mass, Gravitational Mass, Normal Force, Tension, Static Friction, Kinetic Friction. D. Objectives In addition to the Objectives already listed as part of Assignments 1-3, the student should Know the definitions of those quantities listed in the vocabulary section above. Know that a 1 Kg. mass weighs approximately 2.2 lbs near the surface of the Earth.  The student should also be able to explain the difference between weight and mass. Know the SI unit in which Force is measured, and be able to express this unit in terms of other SI units. Be able to apply the ideas of Newtonian Mechanics to analyze simple systems in which the behavior is determined completely by these ideas. Have familiarity with the types of forces found in the Universe.  The student should be able to distinguish between forces that may be understood in terms of others, and those that currently appear to be "fundamental".  When presented with a new "non-fundamental" force, the student should be able to suggest an explanation for the force in terms of "fundamental" interactions. Understand the simple empirical relationship describing how many frictional forces behave.  The student must also be able to distinguish between static and kinetic frictional forces, and must be able to apply this knowledge in both static and dynamic situations.  Further, the student should be able to give a description of the microscopic processes and forces responsible for producing this empirical relationship.
