Foundations of Gravitation and Free Fall

Gravitation is the fundamental force that governs the structure of the cosmos, from planetary orbits to everyday phenomena like objects falling to the ground. Learning its principles is essential for understanding classical mechanics. By the end of this course, you will have a solid foundation in the concepts of gravity, enabling you to confidently calculate forces, understand motion under gravity, and analyze related concepts like buoyancy and fluid pressure. What you'll learn: * Understand the Universal Law of Gravitation and its mathematical expression. * Distinguish clearly between the gravitational constant (G) and acceleration due to gravity (g). * Calculate the force of attraction between objects using Newton's Law. * Analyze the concepts of mass, weight, and how they change in different environments. * Practice applying the equations of motion to objects in free fall. * Learn the foundational principles of thrust, pressure, and buoyancy (Archimedes' Principle). The course begins by defining key terminology and the historical context of gravitational discovery. It then progresses systematically through the mathematical laws and practical applications, providing written examples and practice problems. This course is specifically designed for absolute beginners in physics or science students seeking a clear, foundational text on gravitation. No prior knowledge of advanced physics or calculus is required. Begin your journey into the laws of gravity today.
