Foundations of Gravitation: Force, Fields, and Orbits

Do you want to understand the fundamental force that shapes the universe, dictating everything from how an apple falls to how satellites stay in orbit? This course provides a complete introduction to the physics of gravitation. By the end of this course, you will possess a strong conceptual and mathematical grasp of gravitational phenomena, enabling you to calculate forces, fields, and velocities in various physical contexts. What you'll learn: * Understand the principles of Newton's Law of Universal Gravitation and the inverse square relationship. * Analyze the concepts of gravitational field, potential energy, and potential at various points in space. * Calculate the variation in acceleration due to gravity (g) based on altitude, depth, and Earth's rotation. * Apply Kepler's Laws of Planetary Motion to describe the geometry and dynamics of celestial orbits. * Determine orbital velocity, time period, and escape velocity for objects in circular orbits. * Practice solving problems related to free fall, weightlessness, and mass versus weight. The material begins with core definitions and the historical context of gravitational laws, progresses through detailed mathematical derivations, and concludes with practical applications in orbital mechanics and free fall scenarios. This course is designed for absolute beginners in physics or students needing a strong foundation in mechanics. No prior advanced knowledge is required.
