Core Concepts in Physics: Work, Energy, Power, and Circular Motion

Classical mechanics concepts surrounding motion, forces, and energy are the essential foundation for all subsequent physics and engineering disciplines. This course provides a rigorous, text-based introduction to these fundamental ideas. By mastering these principles, you will be able to transform complex physical scenarios into solvable equations using conservation laws and precise analysis of motion in two dimensions. What you'll learn: * Understand the precise definitions and relationships of work, energy (kinetic and potential), and power in physical systems. * Analyze uniform and non-uniform circular motion, including centripetal force, angular velocity, and angular acceleration. * Apply the Work-Energy Theorem to solve problems involving varying forces and complex paths. * Differentiate between conservative and non-conservative forces and their critical role in mechanical energy conservation. * Practice dimensional analysis and unit conversion for common mechanics quantities to ensure accuracy in problem-solving. The course begins by defining fundamental concepts of force and motion, progresses through analyzing work and energy transfer, and concludes with applying these laws to systems undergoing uniform and non-uniform circular motion. This program is designed for absolute beginners in physics or students needing a robust, foundational review of classical mechanics. No prior physics knowledge is required.
