Does moon has a gravity?
Everything with mass has gravity. The foice of gravity on the Moon's surface is about 1/6 of what it is on the Earth's surface.
Is there a relationship between the distance a planet is from the sun and its surface gravity?
No. The strength of surface gravity on a planet depends on its size and mass.
How is gravity about the same on Mars and Mercury?
This does seem odd. Mars, with a mass that is about twice the mass of Mercury, has about the same surface gravity. Mars' mass is about .107 the mass of earth, and the mass of Mercury is about .055 the mass of earth. The surface gravity on Mars is about .38 times the surface gravity of earth, and the surface gravity of Mercury is about .38 times the surface gravity of earth as well. The difference is that the mean density of Mercury is about 5.43 grams per cubic centimeter, and the mean density of Mars is about 3.93 grams per cubic centimeter. Mercury is quite a bit more dense, so if you stand on Mercury you are much closer to the center of gravity of the planet. Mercury has a tiny slightly bit more gravity than mercury though.
How weak is the gravity on mercury?
The acceleration of gravity on the surface of Mercury, and therefore the weight of any mass located there, is roughly 37.7% of what it is on Earth's surface.
What determines how much gravity on a planet has?
Its mass. More mass=more gravity Also the distance from the planet's center to its surface, i.e. its radius.
How does the gravity of mars vary with its mass?
-- If the mass of Mars increases, then its surface gravity also increases. -- If the mass of Mars decreases, then its surface gravity also decreases. -- So long as its radius does not change, the acceleration due to gravity on or near the planet's surface is directly proportional to its mass.

What would cause the gravity on the surface of mars to be greater than the gravity on the surface of the moon?
The mass
What is the force of gravity at Pluto's surface on an object with a mass of 100 kg?
The force of gravity at Pluto's surface on an object with a mass of 100kg is approximately 58N .
Why is there more gravity on Pluto than on Earth?
There isn't. The "surface gravity" is dependent on the mass (of the planet, etc.) and the distance of the surface from the center of mass. Pluto has MUCH LESS mass than Earth and the gravity is much less on Pluto.
Is there a relationship between the distance a planet is from the sun and its surface gravity?
No. The strength of surface gravity on a planet depends on its size and mass.
What is the weight in newtons of a 5kg mass?
That depends on the amount of gravity, of course. Weight = mass x gravity. Near the Earth's surface, the value for gravity is approximately 9.8 (meters per square seconds).That depends on the amount of gravity, of course. Weight = mass x gravity.

Why will a dense area of rock under the surface increase the local strength of gravity?
density is directly proportional to the mass density = mass / volume more density, then more mass and more mass, more gravity, as gravity force = mass x gravity acceleration.

How does gravity affect the earths surface?
It makes things weigh more or less, depending on the surface gravity.
