Foundations of Physics: Work, Energy, and Power

Understanding how the physical world operates starts with the fundamental concepts of mechanics. This comprehensive text-based course guides you through the core principles of work, energy, and power, breaking down complex physical relationships into clear, digestible explanations. By reading this course, you will build a solid foundation in classical physics, learning how to analyze forces, calculate energy transfers, and evaluate power in various systems. You will transition from memorizing formulas to truly understanding the physical laws that govern movement and energy. What you'll learn: - Understand the scientific definitions of work, energy, and power and how they differ from everyday language - Apply the work-energy theorem to solve practical mechanics problems - Calculate kinetic and potential energy in conservative and non-conservative systems - Master the law of conservation of energy and analyze energy transformations - Compute power and efficiency in mechanical systems - Practice solving step-by-step physics problems through structured written examples The course begins with essential terminology and basic concepts before progressing to mathematical applications and practical problem-solving. You will explore real-world scenarios to see how these physical laws apply to modern technology and energy systems. This course is designed for beginners, high school students, and anyone seeking a clear, text-only introduction to classical mechanics with no advanced prerequisites.
