Foundations of Physics: Physical World and Measurement

Understanding the fundamental rules of the physical world is the first step toward mastering physics. This course provides a clear, step-by-step introduction to how we observe, measure, and analyze physical phenomena in our universe. You will transition from having a basic curiosity about nature to confidently working with scientific units, measurement standards, and dimensional formulas. What you'll learn: - Understand the fundamental and derived physical quantities that describe our world - Master the International System of Units (SI) and learn how to perform precise conversions - Apply dimensional analysis to verify the accuracy of scientific equations and derive formulas - Analyze measurement errors and understand how to calculate absolute, relative, and percentage errors - Practice working with significant figures and rounding rules to ensure scientific precision - Explore modern measurement techniques and the instruments used to measure length, mass, and time This course begins with foundational definitions, establishing a solid grasp of key terminology and the scientific method before moving on to practical calculations and dimensional analysis. Through structured text-based lessons and practical written exercises, you will build a strong mathematical and conceptual foundation in physics. This course is designed for beginners, high school students, and anyone looking to build a strong foundation in physics from the ground up. No prior physics experience is required.
