Foundations of Physics: Work, Energy, and Power

Understanding how forces do work, how energy is conserved, and how power is transferred is essential for mastering classical mechanics. This text-based course breaks down these fundamental physics concepts into clear, digestible explanations. You will transition from memorizing formulas to deeply understanding the physical laws governing motion, enabling you to approach complex physics problems with a structured, analytical mindset. What you will learn: - Understand the mathematical and physical definitions of work, kinetic energy, and potential energy. - Apply the work-energy theorem to solve diverse mechanical problems. - Analyze conservative and non-conservative forces and their impact on energy systems. - Master the law of conservation of mechanical energy and apply it to real-world scenarios. - Calculate power, efficiency, and energy transfer rates in mechanical systems. - Practice systematic problem-solving frameworks to tackle standard physics exam questions. The course begins with core definitions and mathematical foundations before advancing to energy conservation laws, power calculations, and practical problem-solving strategies. Designed for beginners, pre-university students, and anyone looking to build a strong foundation in classical mechanics without any advanced prerequisites.
