No. At the centre of the earth the acceleration due to gravity is ZERO
The Sun's gravity, at its surface, is about 28 times Earth's surface gravity.
on the surfaceNote:Since the earth's composition is not homogeneous, the gravitational acceleration onthe surface is probably less than what it is some small distance below the surface,but it's certainly greater than at the center.
The Earth's mass, and how far you are from the center of the Earth.
The moon's gravity is about 1/6th of the earth's.
The surface gravity of Venus is about 90% that of Earth.
The force of gravity on the earth is 9.8 m/s^2
Gravity causes air to be denser near Earth's surface.
Because the acceleration of gravity on the surface of any given body depends on the mass of the body and its radius ... the distance of the surface from the center. Mars' mass ... about 11% of Earth's ... and Mars' radius ... about 53% of Earth's ... combine to produce about 38% of Earth's gravitational acceleration at the surface of Mars.
The acceleration of gravity at its surface is currently estimated as 0.4 m/s2 .That's about 4% of the acceleration of gravity on the Earth's surface.
It makes things weigh more or less, depending on the surface gravity.
Gravity pulls the earth and anything on its surface together, toward each others' centers.This is important to understand:-- There is a pair of gravitational forces between you and the Earth.-- One force pulls you toward the center of the Earth.The other one pulls the Earth toward the center of you.-- The forces are equal.Your weight on Earth is the same as the Earth's weight on you.
The surface gravity on Io is very low compared to Earth, due to its low mass, around 0.183g or 18.3% of the Earths pull at the surface. this is just a little more than the surface gravity on our own moon, which is about 16.5% of earths pull.
