No, the force of gravity is not the same everywhere on earth. There are subtle differences between the force of gravity on the surface of the earth depending on location. As the earth is what is called an oblate shperoid with a bit of a bulge around the equator (because of its rotation), the poles are actually a bit closer to the center of gravitation of the earth. That means that, in general, a person would weigh a bit more at the poles than at the equator.
The acceleration due to gravity is not very constant. There are measurable differences at the equator (where it's a bit lower) and the poles, and altitude also has an effect.
But for most routine calculations, you can use 9.8 m/s2. Taken to five decimal places, it's 9.80665 m/s2.
There is a gravitational constant in the universe, but the force exerted by gravity is not the same everywhere. That's because gravity is directly proportional to mass. A person who weights 200 pounds on earth would weigh about a bit over 33 pounds on the moon. The mass of the individual has not changed, but the effect of the gravity of the earth is much greater than that of the moon (because of the difference in their gravities). That is what accounts for the difference in weight of one 200-pound person.
Two reasons: 1. Different distances from the Earth's center; 2. A "centrifugal force" that counteracts gravity in part.

Yes. No matter where you are, the force of gravity between two objects is always
F = G m1m2/R2 .
Since the planets all have different masses and different sizes, a test mass ...
such as your body or a standard laboratory rock ... will have a different weight
on each planet.
No, it varies by about 0.01 Nkg-1 (possibly less) between the poles and the equator, due to the extra distance there and the higher speed.

On the earths surface gravity pulls you down.
No, Its gravity is much lower due to a lower overall mass of the planet. Mars' gravity is about 37.6% of the Earths.
Gravity.
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.
In simple terms... gravity ! Gravity is holding the air close to the surface of the Earth. The further away you are from the surface - the lower the gravity - and thus the lower the air pressure.
The Sun's gravity, at its surface, is about 28 times Earth's surface gravity.
Earths surface of gravity is 4.6m/s2 more than moons.
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.
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.

38% on its surface.

The moon's gravity is about 1/6th of the earth's.
It makes things weigh more or less, depending on the surface gravity.
The Gravity becomes less
Gravity causes air to be denser near Earth's surface.
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.
