on the surface
Note:
Since the earth's composition is not homogeneous, the gravitational acceleration on
the surface is probably less than what it is some small distance below the surface,
but it's certainly greater than at the center.
Earths gravity acts on everything from its center of gravity to everything else's center of gravity.
An observer would experience the greatest force due to Earth's gravity at its surface, which is closest to the center of the Earth and where the gravitational acceleration is strongest.
Yes, Earth's gravity pulls objects towards its center. The force of gravity between Earth and objects on or near its surface causes everything to be pulled towards the center of the planet.
The Sun's gravity, at its surface, is about 28 times Earth's surface gravity.
On the earths surface gravity pulls you down.
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.
The force of gravity on the earth is 9.8 m/s^2
38% on its surface.
The moon's gravity is about 1/6th of the earth's.
The percentage of Earth's gravity on the surface of the Moon is about 16.5%.
The Gravity becomes less
if you double the earths density say , standing at the surface you would experience twice the acceleration, weight would be doubled
