These two forces influence motion such as orbital dynamics, rotational behavior of celestial bodies, free-fall trajectories, and the evaporation of matter within a gravitational field. Local activities are affected by larger bodies through the acceleration due to gravitational attraction (g), the Newtonian gravitational attractive force (Fn), the actual gravitational attractive force (Fa), and the buoyancy force of the gravitational field (B). 09 30 2025 34 36 10.14331/ijfps.2025.330176 https://www.fundamentaljournals.com/index.php/ijfps/article/view/262
