Gravitation: Concepts, Laws, and Applications in Physics

Gravitation is the fundamental force shaping our universe, governing everything from terrestrial motion to planetary orbits. This course provides a rigorous, analytical introduction to gravitational theory, enabling you to calculate forces, energy, and potential fields and apply these principles to essential orbital mechanics problems. This course focuses on building a deep, practical understanding of classical gravitational physics. What you'll learn: * Learn the definitive statement and application of Newton's Law of Universal Gravitation. * Understand the variations in acceleration due to gravity (g) based on altitude, depth, and planetary rotation. * Calculate gravitational potential energy and potential for various mass distributions. * Master Kepler's Laws of Planetary Motion and apply them to analyze elliptical orbits. * Determine escape velocity, orbital velocity, and the mechanics of satellite motion. * Practice solving complex problems involving gravitational fields and energy conservation. We begin with foundational definitions and vectors, progressing through the core laws and mathematical derivations before applying concepts to planetary and satellite dynamics. This course is designed for absolute beginners in physics, high school students, or anyone seeking a solid, prerequisite-free introduction to classical mechanics.
