| Course description |
|
Motion of objects which are found around us in daily life, such as automobiles and aeroplanes, are on the rule of classic physics, or Newton's law of motion. Then in order to understand the real motion of object, it is required to develop the equation of motion and solve it. In this course, the treatment will be lectured for typical cases. In addition to that, the concepts of "work" and "energy" are introduced to obtain deeper understanding on motion, from the different point of view rather than the equation of motion. Furthermore, the concept of "angular momentum" is introduced to understand the motion of rotation. The mathematical treatments will be lectured to understand and apply these concepts, if needed. |
| Expected Learning |
|
Mechanics is the base knowledge for the field related to physic, then it is very helpful to understand the topics in the field of mechanical systems engineering especially. The goal of this course is to understand the concepts related to motion, work, and energy which are accompanied by resistance, vibration, and rotation, and to apply these knowledges to solve the given situation. Not only these knowledges and application ability, it is also expected to apply the technical terms to describe the given situation, to express the situation with proper mathematical formula, and to derive the final solution. It is expected for the participants to understand that these three are the standard topics to be included in engineering discussion. See the Curriculum maps. * Refer to the curriculum maps. |

* following is just provided as an example; the number at each end represent the chapter in the textbook * the earlier half is relatively slow to encourage the correct understanding, and the latter half will be gradually speeded-up based on the knowledges already obtained. week-1 : guidance of this course, (6.1) momentum by applied force week-2 : (6.2) angular momentum, (6.3) motion equation for rotation week-3 : (6.4) effect of central force week-4 : (7.1) effect of universal gravity applied with spherical shell theorem week-5 : (7.2) motion of stars applied by universal gravity, (8.1) inertial force week-6 : summery of chap.6 & 7 week-7 : (8.2) centrifugal force, (8.3) Coriolis force week-8 : (8.4) motion equation for rotating coordinate system week-9 : (9.1) center of gravity, relative motion for coupled bodies week-10 : (9.2) motion of the system containing more bodies week-11 : (9.3) collision of two bodies week-12 : (9.4) motion of two bodies constrained with springs week-13 :(10.1) (10.2) stability and motion of rigid body week-14 :(10.3) rotation movement of rigid body, and (10.4) strick power week-15 : final test for the topic of latter half mainly |
| Prerequisites |
|
Certification of physics in high school level. Basic knowledge on the calculation of vectors, derivation and integration In addition to 30hours that students spend in the class, students are recommended to prepare for and revise the lectures, spending the standard amount of time as specified by the University and using the lecture handouts as well as the text specified below. |
| Required Text(s) and Materials |
|
(Japanese version is, available at COOP book store in Koganei-campus) "Rikoukei no tame no Toku! Mechanics edition-2", by Osamu HIRAYAMA and Shunjiro SHINOHARA, Koudan-sha Scientific |

| Assessment/Grading |
|
Basic points are earned through followings, 1 ) Tests 60% ( mid test : 30%, final test : 30%) 2 ) Quiz 40% (Quiz at each class) Questions during the class or after the class will earn as bonus points. Attendance is minimum requirement through the semester ( if below this, the grading is "D" even if you obtain full-marks for the two tests) Grading is based on the regular rule described in "Study guide", Ri-shu-annai 2022, which is provided to you at the beginning of 2022. |
| Message from instructor(s) |
|
Understand the story of each concept is important. Be familiar with the mathematical treatments, because the expression in engineering is in Mathematics. Indiscriminate memorizing would not be powerful anymore, because it is expected what is proper by yourself to explain the reason to others! |
| Course keywords |
| expression of motion, Newton's law of motion, how to solve the differential equation, work, energy, angular momentum |
| Office hours |
| after each class (if needed, ask for other occasion) |
| Remarks 1 |
|
participants should register for this course in "Moodle" system, as Physics Basics (Lecturer : Koji IKEDA) additional handout will be uploaded for your own download through Moodle |
| Remarks 2 |

Grading results in each year : the number in ( ) represents whose attendance is below the required level 2020: S 18, A 41, B 26, C 15, D 14 (6) * all lectures are through on-line because of COVID-19 2019: S 1, A 10, B 47, C 46, D 22 (5) ============================= before 2019, older curriculum is applied as Physics BASIC and Physics Basic Exercise, not just Dynamics 1. there are several differences between present curriculum and older curriculum, then the results for older curriculum are not shown. |
