Centre of Mass and Linear Momentum for Physics and Engineering

Understanding how systems of particles move as a single unit is a cornerstone of classical mechanics and structural engineering. This text-based course guides you through the fundamental principles of the centre of mass, momentum, and collisions, transforming abstract physics equations into intuitive, practical problem-solving skills. You will transition from analyzing single point masses to evaluating complex, multi-body systems, giving you the analytical tools needed for advanced physics study and real-world engineering applications. What you'll learn: - Learn the key terminology and foundational definitions of system particles and discrete mass distribution. - Calculate the centre of mass for both continuous bodies and multi-particle systems using integration and symmetry. - Understand the relationship between external forces, linear momentum, and the motion of the centre of mass. - Apply conservation of momentum to solve elastic and inelastic collision problems. - Analyze real-world applications, including basic rocket propulsion and modern robotic stability principles. - Practice solving rigorous mechanics problems through step-by-step written derivations and guided exercises. The course begins with essential definitions of mass distribution before moving systematically through translational dynamics, collision theory, and practical engineering applications. This course is designed for beginners, physics students, and aspiring engineers looking to build a rock-solid foundation in mechanics. No prior advanced physics background is required, as we build up from basic algebraic concepts.
