Worked Example of 2 Particle System - MATLAB Tutorial - Implications of Energy and Momentum Conservation

Explore a comprehensive tutorial on the dynamics of a two-particle system using MATLAB. Learn about the center of mass corollary and its implications for energy and momentum conservation. Delve into decomposing the motion of a particle system into center of mass movement and motion around it. Work through a detailed example of a spring-mass system with two particles, utilizing a center of mass-centered frame. Discover how the absence of external forces and the presence of conservative internal forces lead to the conservation of total angular momentum and energy. Apply these principles to reduce the model to a single first-order ordinary differential equation. Gain hands-on experience solving this problem using MATLAB, enhancing your understanding of space vehicle dynamics and computational methods in engineering.
