Physics Foundations: Work, Energy, Power, and Circular Motion

Classical mechanics forms the backbone of physics, yet connecting work, energy conservation, and rotational dynamics can often feel overwhelming. This text-only course guides you through these fundamental concepts with clear, structured explanations and step-by-step derivations. You will learn how to break down physical systems, apply conservation laws, and analyze circular trajectories with complete confidence. What you'll learn: 1. Understand the exact relationship between force, displacement, and work done by constant and variable forces. 2. Apply the Work-Energy Theorem and the law of conservation of mechanical energy to complex systems. 3. Analyze power, mechanical efficiency, and the critical distinction between conservative and non-conservative forces. 4. Master the dynamics of circular motion, including centripetal acceleration, tension, and the banking of curves. 5. Practice structured problem-solving methodologies to tackle standard mechanics problems systematically. We begin with foundational definitions of work and kinetic energy, progressing systematically through potential energy, conservation laws, power, and ultimately the mechanics of uniform and non-uniform circular motion. This course is designed for high school students, introductory college physics learners, and exam prep candidates who want to build a strong conceptual and mathematical foundation from the ground up, with no advanced prerequisites required.
