Foundations of Physics: Work, Power, and Energy

Understanding how forces interact with objects to perform work and transfer energy is the bedrock of classical mechanics. This comprehensive text-based course guides you through these fundamental physics concepts without overwhelming jargon. By the end of this course, you will develop a strong intuitive and mathematical understanding of work, kinetic and potential energy, conservation laws, and power, enabling you to tackle foundational physics problems systematically. You will learn to: Understand the scientific definitions of work, kinetic energy, and potential energy; Apply the work-energy theorem to solve real-world mechanical scenarios; Calculate power output and efficiency in various physical systems; Analyze conservative and non-conservative forces and their impact on energy conservation; Practice step-by-step problem-solving methodologies for mechanical systems; Explore modern energy conversion principles and basic conservation models. The course starts with key terminology, basic concepts of force and displacement, and foundational definitions before progressing to complex systems of conservation and energy transfer through detailed written explanations and structured practice exercises. This course is designed for beginners, students preparing for introductory physics exams, or anyone seeking a solid conceptual foundation in mechanics with no advanced mathematical prerequisites.
