Universal Gravitation and Kepler's Laws for Beginners

Have you ever wondered how planets stay in orbit or how scientists plot courses for spacecraft across the solar system? The answers lie in the foundational laws of gravity and motion developed centuries ago. This course provides a complete, text-based introduction to the classical physics governing everything from falling apples to distant galaxies. By the end, you will be able to analyze orbital mechanics problems and understand the mathematical foundation of space exploration. What you'll learn: * Learn the historical development and modern interpretation of Kepler's Three Laws of Planetary Motion. * Master the application of Newton's Law of Universal Gravitation, including force calculations and potential energy concepts. * Understand the relationship between gravitational force, mass, and distance using the inverse square law. * Apply these foundational laws to calculate orbital periods, predict satellite trajectories, and determine escape velocity. * Practice fundamental problem-solving techniques for central force motion and energy conservation in gravitational fields. The course begins by defining key terminology and historical context, then moves systematically through Kepler's empirical laws and Newton's theoretical framework. We focus entirely on written explanations and step-by-step mathematical derivations. This course is designed for absolute beginners with no prior experience in advanced physics or orbital mechanics. If you are comfortable with basic algebra, you have all the prerequisites needed. Start your journey into the mechanics of the cosmos today.
