In Fundamental Mechanics 1, students study the motion of a single-particle system. In Fundamental Mechanics 2, the aim is
to understand the motion of extended bodies and systems consisting of multiple particles. More specifically, students deepen
their understanding of important concepts such as the center of mass, angular momentum, moment of inertia, and inertial forces,
and acquire the ability to describe and analyze the motion of many-particle systems and rigid bodies using equations. In addition,
by learning the fundamentals of the mechanics of elastic bodies, students develop a basic understanding of the mechanical
behavior of deformable objects.
Fundamental Mechanics 2 is a course that builds on Fundamental Mechanics 1, in which the mechanics of a single-particle system
is studied, and extends the subject to the motion of many-particle systems, rigid bodies, and elastic bodies. The course also
covers angular momentum and torque, which are essential for describing rotational motion, as well as inertial forces such
as centrifugal force and Coriolis force. Through these topics, students learn how the concepts of mechanics can be applied
to systems with spatial extent and gain a deeper understanding of various types of motion. The course is mainly conducted
face-to-face, but online participation or on-demand materials may also be used when necessary. In such cases, students will
be informed in advance.
- Students will be able to understand the concepts of angular momentum and torque, and apply them to concrete problems.
- Students will be able to understand the difference between internal and external forces, and derive the laws of motion for the center of mass and rotational motion from the equations of motion for many-particle systems and Newton’s third law.
- Students will be able to describe the motion of rigid bodies in terms of equations of motion and solve concrete problems using the moment of inertia.

Assignments in class 30%, midterm examination 30%, and final examination 40% will be used for the overall evaluation. Assignments
in class will be evaluated through short exercises, quizzes, or reports related to each class. The midterm and final examinations
will evaluate students’ understanding of the basic concepts covered in class and their ability to solve problems in mechanics
appropriately by using those concepts.
A total score of 60% or higher is required to receive credit. A score of 60% means that the student understands the basic contents covered in the course and is able to solve fundamental problems related to angular momentum, torque, the motion of many-particle systems, the motion of rigid bodies, inertial forces, and the mechanics of elastic bodies.
In addition, this course is coordinated with the “Learning Support Room.” Depending on the level of understanding, study in the “Learning Support Room” may be required in order to earn credit. Details will be explained in the first class.
