WebThe mass of Earth can be calculated from its radius and g if G is known. G was measured by the English physicist-chemist Henry Cavendish and other early experimenters, who spoke of their work as “weighing the Earth.” WebYou basically end up with a simple relationship: for the same gravity, the ratio of the planet’s radius to that of Earth equals the inverse ratio of their densities. Earth is the densest (~ 5.5 g/cm^3) of the rocky planets in our own solar system.

WebIt's an assumption that has made introductory physics just a little bit easier -- the acceleration of a body due to gravity is a constant 9.81 meters per second squared. Indeed, the assumption would be true if Earth were a smooth sphere made of uniform elements and materials. Quite the opposite is true, however. Web10 de mar. de 2024 · I like these way better than all the trains, planes, and magnet answers. The reason other planets have lower gravity is because they are lighter. Just like moons. To note though: Rotation of a planet does not affect the gravity, but the rotation of a planet reduces the gravitational pull experienced by an object on the surface of that planet.
