Foundational Physics: Units, Dimensions, Error Analysis, and Kinematics

Succeeding in competitive physics exams requires a rock-solid grasp of the absolute basics of measurement and motion. Without a clear understanding of how units work, how errors propagate, and how objects move, solving complex multi-concept problems becomes nearly impossible. This text-based course guides you step-by-step through the essential theories, mathematical derivations, and problem-solving strategies needed to master these foundational physics topics. You will develop the analytical skills required to dissect exam-style questions with confidence. Learn to understand the international system of units and the core principles of dimensional analysis. Apply dimensional homogeneity to verify physical equations and estimate physical quantities. Calculate absolute, relative, and percentage errors using systematic error propagation techniques. Analyze the kinematics of motion in one and two dimensions, including projectile and relative motion. Practice solving rigorous, exam-style physics problems through structured written explanations and step-by-step derivations. The course begins with key terminology, foundational definitions of physical quantities, and modern measurement standards before progressing to error analysis methodologies. From there, you will read through the mathematical frameworks of kinematics, exploring real-world motion scenarios and analytical problem-solving patterns. This course is designed for aspiring engineering students and physics learners preparing for competitive exams like JEE Main and Advanced who want to build their concepts from the ground up.
