For absolute zero gravitational attraction - Infinity. The gravitational attraction due to the Earth is also zero at the centre of the Earth.

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,
An object at rest on the earths surface has two forces acting upon it what are they and why doesnt the object move?
Gravity and the upward force of the surface the object is resting on.
Why does an object accelerate when it falls towards the earths surface?
The force of gravity pulls it down to the earth.
What is the type of potential energy dependent upon an object's weight and distance from earths surface?
That is called gravitational potential energy.
According to the law of gravitation how does the force of gravity relate to an objects distance from earths center?
F=G(m*M/r^2). If the object is close to the earth's surface then F=mg (where g=9.81 (m/s^2)) is a good approximation.

How does mass and gravity distance effect gravity?
The larger the mass of an object, the greater the force it will exert on other objects. But as the distance from that object becomes greater, the gravitational pull becomes smaller. For example, the sun has a larger mass than the earth, so gravity on the suns surface would be much greater than on earths surface. Also, as you get further and further away from the earth, the less you are influenced by its gravity.
Why does an object accelerate when it falls towards the earths surface?
The force of gravity pulls it down to the earth.
What does the Moon's gravity and earths gravity have in common?
Gravity on the moon has exactly the same characteristics and behavior as it has on Earth and everywhere else. It causes a pair of forces between any two objects, that are proportional to the product of the objects' masses and inversely proportional to the square of the distance between their centers. Because of the moon's much smaller mass, the force between the moon and an object on its surface is only about 16% as strong as the force between the Earth and the same object when the object is on the Earth's surface.
What is the type of potential energy dependent upon an object's weight and distance from earths surface?

What is the downward pull of earths gravity on an object?
9.8
If someone shrunk the earth will there be less gravity?
No. Gravity depends on only two factors: mass and distance from the center of mass of the object. Gravity increases in proportion to the mass of the object and decreases in proportion tot he square of the distance from it. So doubling the mass doubles the gravity. Doubling distance cuts gravity to one quarter the original value. So, if you were to compress Earth to a smaller size without decreasing its mass, gravity where the surface originally was would remain the same. Gravity at the surface in its new position, closer to the center of mass would actually increase.
Explain how earths gravity affects objects that are on or near earth?
All mass attracts all other mass, thats a fact. The force due to gravity between the earth and another object, is dependent on their combined mass (earth and object), and the square of the distance between the centres of gravity.
According to the law of gravitation how does the force of gravity relate to an objects distance from earths center?
F=G(m*M/r^2). If the object is close to the earth's surface then F=mg (where g=9.81 (m/s^2)) is a good approximation.
What is the force exerted on an object by the earths pull called?
Gravity, its weight.
Is gravity dependent on earth?
No. Gravity is dependent on two factors: the mass of the object in question and the distance from its center of mass. So gravity at Earth's surface is dependent on its mass and radius, and Earth is the dominant gravitational body for some distance, but elsewhere, other objects dominate with their own gravity.
