More mass --> more gravity.
no
No, your weight is just the acceleration due to the Earth's gravity,
it increases
It will decrease not by much though it is not noticeable compared to the earths radius
if you double the earths density say , standing at the surface you would experience twice the acceleration, weight would be doubled
You could never match earth's gravity on the moon. You could not increase the amount of gravity on the moon by drilling.
Dan's mass is the same as it is on Earth. His weight, however, is doubled.
Both mercury and mars have a gravity which is around 38% of earths. Mercury's gravity is 37.8% of earths, Mars' gravity is 37.7% of earths.
because all are measured at the same radius from the earths cog, if you doubled this distance, the acceleration would be only one quarter that of the surface
Earths gravity acts on everything from its center of gravity to everything else's center of gravity.
About 0.183g, where one g is the earths gravity, so about one fifth of the earths gravity. It is similar to our own moons surface gravity.
CO2 O2 Sulfur Nitrogen and Hydrogen. each gas is found in a specific quantity which shouldn't increase or decrease
