| Shrnutí: | <p dir="ltr">This paper explores surface gravity, the acceleration caused by gravity at the surface of a celestial body, across a wide range of objects in the universe. We first calculate the surface gravity of major planets and the Moon using Newton’s law of universal gravitation, illustrating how mass and radius influence gravitational strength. These calculations are then extended to stellar objects, including red supergiants, white dwarfs, neutron stars(and pulsars), demonstrating how gravity behaves under extreme conditions. By comparing these results, we see how gravity varies across the universe and how the same simple formula can be applied to both familiar planets and rare stellar objects. This study highlights the importance of surface gravity for understanding planetary environments, stellar evolution, and the limits of gravitational physics.</p> |
