Why does the free fall acceleration of gravity of a particle vary from place to place on the earth's surface?

Please note that the differences are only slight - so slight that you can round
the acceleration due to gravity to a value of 9.8 m/s2, anywhere on Earth,
with reasonable accuracy. The reasons for the (slight) difference are:
1) The Earth is not a perfect sphere. In different places, you are at a different
distance from the Earth's center.
2) The Earth rotates. This produces an apparent centrifugal force. Stated in
other terms, if you are at the equator, while an object falls towards Earth, the
Earth moves away from it due to the rotation (centripetal acceleration).

Why is the acceleration due to gravity on the surface of Mars is about one third the acceleration due to gravity on earths 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.
When you push UP on an object when object is stationary on earths surface you increase your weight when you push DOWN on an object when object is stationary on earths surface you decrease your weight?
No, your weight is just the acceleration due to the Earth's gravity,
Where does gravity pull people and objects?
On the earths surface gravity pulls you down.
What is the acceleration due to gravity near the earth's surface?
9.81 m/s2 gravity is dependant on the total mass of the two bodies, and the distance between their mass centers, and irrespective of any motion or rotation on earth, their would be a very small acceleration due to rotation about the earths axis (0 at the poles , maximum at the equator) , but this is a totally seperate issue
What is the acceleration due to gravity 9000000 meters away from the center of the earth?
If you have a known rate of acceleration and radius (such as at the earths surface), you can use the following equation to calculate the acceleration at another radius.a = k / ((d / r)^2)key:a = new acceleration rate ((m/s)/s)d = new radius (metres)k = known acceleration rate ((m/s)/s)r = known radius (metres)so if:d = 9 000 000 metresk = 9.82 (m/s)/s (acceleration at earths surface)r = 6 371 000 metres (radius at earths surface)then:a = 4.92 (m/s)/s
What is makemakes gravity compared to earths gravity?
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.
What is the surface gravity on earth?
The force of gravity on the earth is 9.8 m/s^2
Why is the acceleration due to gravity on the surface of Mars is about one third the acceleration due to gravity on earths surface?

What is the compare of the earth and the moon in terms of size and surface gravity?
earth is 81.3 times the mass of the moon . acceleration due to gravity at earths surface = 9.82 (m/s)/s acceleration due to gravity at moons surface = 1.62 (m/s)/s . 1 kg at earths surface, force = 1 * 9.82 = 9.82 newtons 1 kg at moons surface, force = 1 * 1.62 = 1.62 newtons
When you push UP on an object when object is stationary on earths surface you increase your weight when you push DOWN on an object when object is stationary on earths surface you decrease your weight?
No, your weight is just the acceleration due to the Earth's gravity,
Why does the acceleration of gravity vary from one point to another on the earths surface?
Different air pressure, so there is more/less air resistance.
Why is acceleration due to gravity the same for all objets?
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
Where do you experience more gravity on earths surface or earths center?
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.
What is the Suns gravity in relation to Earths gravity?
The Sun's gravity, at its surface, is about 28 times Earth's surface gravity.
How much more is Earths surface of gravity than the Moon's?
Earths surface of gravity is 4.6m/s2 more than moons.
Which planets surface gravity is 38 percent that of earths?
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.
How is gravity affected if mass is changed?
if you double the earths density say , standing at the surface you would experience twice the acceleration, weight would be doubled
