Physics I [Phys 161]                              Spring 2004 Assignment #5 Reading, Vocabulary & Objectives A. Availability and Due Dates Assignment #5 is available Monday, March 1, 2004.  The target date for its successful completion is Monday, March 15, 2004.  In any event, all problems from Assignment #5 must be successfully completed and turned in by 5:00 pm on Wednesday, March 24, 2004.  If this requirement is not met, the student will not be allowed to take Exam 3, to be given in class on Friday, March 26, 2004.   B. Reading As preparation for completing the problems in Assignment #5, read Chapters 6 & 7 in Serway & Jewett. C. Vocabulary As part of Assignment #5, the following vocabulary words must be understood and memorized in addition to those already listed on Assignments 1-4: Non-Uniform Circular Motion, Resistive Force, Drag Coefficient, Terminal Speed, Work, Scalar (or "Dot") Product, Spring (or "Elastic") Constant, Hooke's Law, Kinetic Energy, Elastic Potential Energy, Internal Energy, Heat, Conserved, Mechanical Waves, Average Power, Instantaneous Power, Conduction, Convection, Electromagnetic Radiation, Closed System, Conservative Force, Non-Conservative Force. D. Objectives In addition to the Objectives already listed as part of Assignments 1-4, the student should Know the definitions of those quantities listed in the vocabulary section above. Understand the meaning of the Dot Product (or Scalar Product) of two vectors.  The student should be able to calculate dot products, and should be able to use dot products to calculate quantities as needed in mechanics. Know the SI units in which Energy and Power are measured, and be able to express each of these units in terms of other SI units. Be able to distinguish between inertial and non-inertial (accelerated) frames of reference.  Specifically, the student should be able to devise appropriate experiments in order to determine whether a particular frame of reference is inertial or not.  Additionally, the student should be able to calculate the fictitious forces present in simple Non-Inertial Reference Frames. Understand the concept of Work, and be able to determine the amount of work done by or on an object given sufficient information.  The student should also understand the concept of Power. Know the Work-Energy Theorem and understand the concept and definition of Kinetic Energy.  In the absence of any potential energy, the student should be able to show that the work done on an object is equal to its change in kinetic energy. Understand the difference between Conservative and Nonconservative forces, and be able to explain why a conservative force allows the definition of an associated potential energy, while a nonconservative force does not.  The student should be able to construct a potential energy corresponding to any given conservative force, and vice versa. Understand what is meant by a "Hookian restoring force", or "linear restoring force". Be able to determine the Drag due to air resistance acting on an object moving at high speed if the object's Drag Coefficient is known.
