gravity-moon_198x198Gravity is the force of attraction of bodies. Its intensity depends on the mass: the more mass, the higher the gravity.  This is the reason why the gravitational pull is greater on Earth than on the Moon, because Earth is considerably larger and heavier than the Moon. The gravitational acceleration on Earth is with approx. 9.8 m/s² six times as strong as on the Moon with approx. 1.6 m/s². This is why astronauts are able to jump higher on the Moon than on Earth and objects fall to the ground at a lower speed. [read more] “The gravity on the Moon”
