Physics Foundations: Laws of Motion, Work, Energy, and Power

Struggling to connect the dots in classical mechanics or preparing for an upcoming physics exam? Understanding the fundamental laws that govern physical movement and energy transitions is the key to academic success in science and engineering. This course provides a streamlined, conceptual revision of mechanics, focusing on Newton's laws of motion and the principles of work, energy, and power. You will move from memorizing formulas to deeply understanding physical interactions and confidently solving numerical problems. By breaking down complex topics into clear, readable explanations, you will build the intuition needed to tackle challenging physics questions. What you'll learn: - Understand Newton's three laws of motion and their real-world applications - Master the systematic use of free-body diagrams to resolve forces in equilibrium and acceleration - Apply the work-energy theorem to analyze conservative and non-conservative forces - Differentiate between kinetic and potential energy, and apply the law of conservation of energy - Calculate power, efficiency, and analyze elastic and inelastic collision scenarios - Practice structured problem-solving frameworks to approach physics word problems systematically The course begins with foundational definitions of force, inertia, and momentum, before moving step-by-step through vector-based force analysis, energy conservation, and collision mechanics. No advanced calculus is required, making this ideal for beginners, high school students, or anyone needing a clear, text-based refresher on classical mechanics.
