Rigid Body Dynamics

Korea Advanced Institute of Science and Technology(KAIST)

Rigid Body Dynamics is a fundamental course in mechanical engineering that delves into the principles of force, motion, and energy. Through a series of lecture videos, practice problems, and standalone homework, students will gain a deep understanding of dynamics, including the integration of Newton's 2nd law over time and displacement.

The course encompasses various topics, such as rotation, relative velocity, relative acceleration, Newton-Euler equation, work and energy, impulse and momentum, 3D rotation, kinematics of general 3D motion, angular momentum, equations of motion in 3D, gyroscopic motion, and steady precession.

By the end of the course, students will have acquired the knowledge and skills necessary to analyze and solve complex problems related to rigid body dynamics, laying a strong foundation for their future endeavors in mechanical engineering.
