Academic Year School/Graduate School Lecture Code 2020Year Liberal Arts Education Program 68150001 Foundation Courses 一般力学I[1工一] イッパンリキガク1 General　Mechanics I TANAKA KENICHI タナカ　ケンイチ Higashi-Hiroshima 1st-Year,  First Semester,  1Term (1T) Thur5-8：IAS K314 Lecture Lecture-oriented class, Projection (PowerPoint) will be used. 2 J : Japanese 1 : Undergraduate Introductory 25 : Science and Technology 06 : Physics Newton’s equation of motion, vector, differential equation, oscillation, momentum, angular momentum, work, potential energy, mechanical energy, gravitation Mechanics is one of the mainstays of physics and engineering as well as electromagnetics, and hence an important subject for students in the department of science and engineering as a foundation to be acquired.Our goal in General Mechanics is to systematically provide the principles and laws of mechanics for engineering students. Students coming out of this class should have a deep conceptual understanding of classical Newtonian mechanics. This course, General Mechanics I, provides instruction in one-particle dynamics and mathematics required for the understanding of this lecture. lesson 1: Basis of the vector and the operations such as scalar product, vector product and the calculuslesson 2: Various coordinate systems such as Cartesian coordinate, polar coordinate and cylindrical coordinate systemlesson 3: Position, velocity, and acceleration vector and the relationships in terms of temporal differential: Newton’s first law of motion (the law of inertia) and inertial frames of reference.lesson 4: Newton’s second law (Newton’s equation of motion) and third law of motion (law of action and reaction): Methods for solving the differential equations of linear motion with constant acceleration and free-fall motionlesson 5: Methods for solving the constrained motionlesson 6: The equation of simple harmonic motion and the solving method: Complex number and Euler’s formulalesson 7: The methods for solving second order linear ordinary differential equations with constant factorslesson 8: The equation of dumped oscillations and the solving methods: the features of dumped oscillationslesson 9: The equation of forced oscillations and the solving methods: the features of forced oscillationslesson 10: Momentum and Impulselesson 11: Angular momentum and moment of forcelesson 12: Integral representations for the work done by forces: The relationship between work and kinetic energy through the equation of motionlesson13: Conservative forces and potential energylesson14: Conservation of mechanical energy and the problems for applicationlesson15: Universal gravitation and the potential energyterm-end exam Each teacher specifies the textbook and other books for reference. Handouts will be provided. Projections, PowerPoint or movie, will be also used. Read the textbook and/or handouts very carefully before the each lecture and solve exercises in the textbook after the class. Freshmen should take the specified class.The actual class schedule might vary flexibly depending on the students and the situation. So please ask the actual schedule to each teacher of the class. About 70% by the term-end exam and about 30% by the attitude toward the class. Please fill in the class improvement questionnaire which is carried out on all classes.Instructors will reflect on your feedback and utilize the information for improving their teaching.
