Physics is often called the fundamental science because it seeks to uncover the universal laws that govern everything around us. It is the study of matter, energy, space, and time—and how they interact. From the graceful orbit of planets and the fall of an apple, to the energy that powers our homes, the vibrations that create sound, and the light that allows us to see—physics lies at the very core of our understanding of the universe.

In this course, Foundations of Physics, you’ll embark on a journey to discover how the world works at its most essential level. We’ll begin by asking simple but powerful questions: What is physics? How do scientists investigate the world? Why do measurement and precision matter so much? These opening topics will give you the tools and mindset of a physicist. Step by step, you’ll then explore the major building blocks of physics: motion and forces, energy and heat, electricity and magnetism, waves and sound, and the nature of light. Together, these themes form the groundwork for all later study in science and engineering.

But this course is about more than just learning formulas and definitions. It is about making connections—between scientific ideas and real-world experiences. You’ll see how physics explains everyday phenomena, from the way bicycles move and bridges stand, to how smartphones function and how ecosystems depend on energy flow. By understanding these principles, you’ll gain not only academic knowledge but also practical insights into the technologies and natural processes that shape your daily life.

By the end of the course, you will have developed a strong foundation in physics—one that prepares you for further study in science, medicine, technology, and engineering. More importantly, you’ll cultivate curiosity, problem-solving skills, and an appreciation for the beauty of the natural world.

So get ready to think critically, ask questions, explore patterns, and uncover the principles that govern our universe. Welcome to the Foundations of Physics—your first step into the language of nature itself.
