Practical Measurement of Earth's Gravity

This research presents a simplified framework to understand Earth’s gravity using the formula Ge=W/m*d. The study explains how gravity acts on objects, how it can be measured, and how height influences gravitational effects. Practical examples, such as comparing the fall of an iron ball and a balloon, are used to highlight the role of air resistance. The proposed model is compared with Newton’s classical law of gravitation and Einstein’s modern theory of General Relativity, showing how simplified formulas can support workplace training and educational contexts while modern theories provide universal accuracy.
