Foundational Physics: Newton's Laws of Motion, Work, Energy, and Power

Understanding how forces shape our physical world is the essential starting point for all science and engineering disciplines. This text-only course guides you through the core concepts of mechanics, turning complex equations into intuitive, logical steps. You will begin by exploring foundational definitions of force, inertia, and mass before moving on to practical problem-solving. By reading through clear explanations and structured written examples, you will learn to analyze physical systems, calculate work and energy transformations, and apply conservation laws to real-world scenarios. What you'll learn: 1. Understand the foundational concepts of force, inertia, and Newton's three laws of motion. 2. Apply free-body diagram analysis to solve friction, tension, and gravitational problems. 3. Master the work-energy theorem and calculate work done by both constant and variable forces. 4. Analyze conservative and non-conservative forces alongside the conservation of mechanical energy. 5. Calculate power, efficiency, and the mechanics of elastic and inelastic collisions. 6. Explore modern applications of mechanics in engineering and basic numerical estimation techniques. The course begins with essential terminology and fundamental laws, gradually building toward complex energy systems and conservation principles through structured written exercises. Designed for beginners, students preparing for introductory physics exams, or anyone seeking a solid grasp of classical mechanics, this course requires no prior physics background.
