3D Engineering Dynamics: Kinematics and Kinetics of Rigid Bodies

Designing mechanical systems, robotics, or aerospace structures requires a deep understanding of how objects move in three dimensions. This text-based course guides you through the fundamental principles of 3D engineering dynamics without overwhelming jargon. You will transition from basic physics concepts to analyzing complex 3D systems by exploring kinematics (the geometry of motion) and kinetics (the forces causing motion). Through clear written explanations and step-by-step mathematical breakdowns, you will gain the confidence to model real-world mechanical behaviors and prepare for modern computational simulation workflows. What you'll learn: - Understand the fundamental terminology of 3D rigid body kinematics, including position, velocity, and acceleration - Apply vector mathematics to describe angular motion and coordinate system transformations - Analyze the kinetics of 3D motion by calculating forces, moments, and inertia tensors - Formulate equations of motion for rigid bodies using classical Newtonian mechanics - Explore modern computational dynamics concepts used in simulation and CAD software The course begins with foundational definitions and coordinate systems before moving into kinematic analysis of rotating bodies. You will then progress to kinetics, studying how forces and torques dictate 3D motion in practical engineering scenarios. This course is designed for aspiring engineers, robotics enthusiasts, and students seeking a clear, beginner-friendly introduction to 3D dynamics. No prior advanced engineering background is required, though a basic grasp of algebra and physics is helpful. Start exploring the mechanics of 3D motion today.
