Introduction to Work, Energy, and Power

Understanding how forces cause motion and how energy is transferred is fundamental to physics, engineering, and everyday technology. This text-based course guides you through the core concepts of work, energy, and power from the ground up. You will learn to define these terms precisely, perform essential calculations, and apply these principles to real-world mechanical and electrical systems. What you'll learn: - Understand the scientific definitions of work, energy, and power along with their standard SI units - Analyze different types of work, including positive, negative, and zero work in physical systems - Distinguish between kinetic and potential energy and apply the law of conservation of energy - Calculate power output and mechanical efficiency in both simple machines and modern energy systems - Solve practical physics problems using step-by-step mathematical formulas and written scenarios Starting with foundational definitions, the course progresses from basic force-displacement relationships to complex energy conservation scenarios. Each concept is reinforced with written walkthroughs and conceptual exercises designed to build your problem-solving confidence. This course is designed for beginners, students, and aspiring engineers looking for a clear, conceptual introduction to mechanics without any prior physics background.
