Foundations of Physics
Physics is often called the “fundamental science” because it seeks to explain the basic laws that govern the universe. From the motion of planets and falling apples, to the energy powering our homes and the light that allows us to see—physics is at the heart of it all.
In this course, Foundations of Physics, you’ll begin your journey into understanding how the world works at its most essential level. We’ll start with the basics: what physics is, the scientific method, and why measurement and precision matter. Then, step by step, you’ll explore motion, forces, energy, electricity, waves, sound, and light—core topics that build the groundwork for more advanced studies.
By the end of this course, you won’t just know definitions and formulas—you’ll see how physics connects to your daily life, from the technology you use to the natural world around you. This foundation will prepare you for deeper learning in science, engineering, medicine, and beyond.
So, get ready to ask questions, explore patterns, and uncover the principles that shape our universe. Welcome to the Foundations of Physics!
What is Physics? The Scientific Method and Measurement
Ever think about why a ball drops, how sound comes from a speaker, or what powers a car? That’s physics at work. It’s the science behind matter, energy, motion, and forces—explaining how the universe operates, from tiny particles to massive galaxies.
Motion, Forces and Newton's First Law
Physics explains how things move and interact—from a rolling ball to orbiting planets. By studying motion, speed, and acceleration, we can predict behavior with precision. These principles are essential in fields like engineering, sports, and everyday life
Newton’s Second and Third Laws of Motion
Building on our understanding of Newton’s First Law, which describes objects at rest or in uniform motion, delve into how forces cause changes in motion. Explore the fundamental principles that govern how objects accelerate and how forces interact between different bodies.
Gravity and Other Forces
Every object in the universe is constantly influenced by forces. These invisible pushes and pulls dictate how things move, or why they stay still. From the act of walking to the orbit of planets, understanding forces is fundamental to comprehend the physical world around us.
