Foundations of Physics: Gravitation, Oscillations, and Waves

Understanding the physical forces that govern our universe is the key to mastering introductory physics. This text-based course breaks down complex mathematical models and physical laws into intuitive, digestible concepts. By reading through these structured guides, you will transition from memorizing formulas to genuinely understanding the mechanics of gravity, planetary motion, periodic systems, and wave propagation. You will learn to: Understand the fundamental laws of gravitation, including Kepler's laws and gravitational potential energy; Analyze simple harmonic motion and the mechanics of oscillating systems like pendulums and springs; Explore the properties of waves, distinguishing between transverse, longitudinal, and standing waves; Apply mathematical equations to solve physics problems with step-by-step written walkthroughs; Discover modern applications of these principles, from gravitational wave detection to acoustic resonance. The course begins with core terminology and essential definitions of force and motion, steadily progressing through gravitational fields, oscillatory behaviors, and wave mechanics. Each module features clear written explanations, theoretical derivations, and practical practice problems. This course is designed for high school students, academic exam candidates, and physics beginners. No advanced background in calculus is required; basic algebra is all you need to start.
