Foundations of Physics: Conservation of Mass and Inertial Mechanics

Why does mass remain constant in classical systems, and how do we actually define what mass is? Understanding these core principles of physics is essential for anyone looking to build a solid foundation in the physical sciences. This text-based course guides you through the fundamental concepts of mass conservation, the critical distinction between inertial and gravitational mass, and the mechanics of Galilean relativity. You will transition from basic definitions to a clear conceptual understanding of how objects move and interact across different frames of reference. What you will learn: 1. Understand the law of conservation of mass and its applications in closed systems. 2. Differentiate between inertial mass and gravitational mass through clear conceptual breakdowns. 3. Explain the equivalence principle and how it connects classical mechanics to modern physics. 4. Apply the principles of Galilean relativity to analyze motion in different reference frames. 5. Solve foundational conceptual problems using step-by-step written exercises. The course starts with essential terminology and the historical context of mass conservation before moving into the properties of mass and classical relativity. You will progress through structured readings and practical written scenarios designed to reinforce your understanding. This course is designed specifically for beginners, science students, and physics enthusiasts with no prior advanced mathematics background required.
