Fundamentals of Force, Work, and Energy

Transitioning from describing motion to understanding the causes of motion—forces and energy—is a crucial step in learning physics. This course provides the foundational concepts necessary to bridge that gap. You will learn the core mathematical and conceptual framework needed to analyze dynamic physical systems. By mastering the concepts of force, work, and energy, you will be equipped to set up and solve complex problems involving motion, energy transfer, and mechanical interaction. What you'll learn: * Understand the vector definitions of force, momentum, and impulse, and how to apply Newton's Laws of Motion. * Apply the Work-Energy Theorem to calculate energy transfers resulting from constant and variable forces. * Master the mathematical formulations for kinetic energy, potential energy (gravitational and elastic), and power. * Analyze systems using the principle of Conservation of Mechanical Energy, distinguishing between conservative and non-conservative forces. * Practice advanced problem-solving techniques, including the use of free-body diagrams and vector decomposition in dynamic scenarios. * Learn the foundational concepts of momentum conservation and apply them to analyze collisions and interactions in one and two dimensions. The course begins with clear definitions and the mathematical language of dynamics before moving into detailed explanations of work, potential energy, and conservation laws. We emphasize structured problem-solving frameworks and practical application through written examples. This course is designed for absolute beginners in physics or those needing a solid review of classical mechanics. No prior knowledge of dynamics or advanced mathematics is required.
