What is the distance from earths surface for zero gravity of an object?
For absolute zero gravitational attraction - Infinity. The gravitational attraction due to the Earth is also zero at the centre of the Earth.
Gravitational potential energy is the energy an object possessesdue to its position related to earths surface?
Gravitational potential energy is: m*g*h m=mass g=acceloration due to gravity h=height in relation to zero level/energy because earth's surface (with rare exception) is zero level/energy, meaning that you cant make things fall further than the surface of earth; the potential energy of an object changes based on how much distance you put between the surface and the object, yes.
Is potential energy on the surface of earth is always zero?
That depends on what reference level you have chosen. If the (arbitrary) reference level you chose is Earth's surface, then anything on the Earth's surface has zero potential energy. If you choose some higher reference level, an object on Earth's surface has a negative potential energy. If you choose a lower reference level, an object on Earth's surface would have a positive potential energy.
What is the magnitude of gravitational field at earth's center?
If gravity on the surface of Earth is 9.8Nkg, then at the centre it would be 0Nkg
Can you calculate the gravitational potential energy of a pendulum?
the pendulums gravitational energy refers to the gravitational energy of the bob (the string is considered to be mass less) the energy calculated for practical purposes is considering the mean position of the pendulum as the state of zero energy. but aesthetically the gravitational (potential) energy of a body only depends on its distance from the centre of the earth. the energy is equal to (gravitational constant(G))*(mass of earth)*(mass of bob) /(distance of bob from earths centre)
Where are the zero gravity place on the surface of the earth?
For any object that has mass, there is no place on the surface of the Earth where the gravitational force on the object is zero.

How is nitrogen in the atrmosphere brought to the earth's surface?
nitrogen is brought to earths surface by the gravitational pull of zero gravity
What is the equation for calculating an object's gravitational potential energy?
The equation to calculate an object's gravitation potential energy is: PE=MGH where: PE is gravitational potential energy M is the objects mass G is the acceleration due to the gravitational pull of the Earth on its surface ( 9.8 m/s2) H is the height from the location that would give it zero potentional energy (generally the ground)
What is the potential on the surface of the earth?
There is no absolute measure for potential energy. The calculation for potential energy depends on the chosen reference level. Quite often, the Earth's surface is chosen as the reference level - in this case, an object on the surface will have zero potential energy.

Does the gravitational force of attraction of the earth become zero at some measurable height above the surface of earth?
No. The gravitational force of the earth can be effectively cancelled out by some object, such as the moon, which pulls in the opposite direction, but it does not go to zero just because of the distance at any point.
What is the gravitational potential energy at the center of the earth?
Ideally, if the earth were a perfect sphere, the gravitational potential energy would be zero. In the center of a sphere all other points within the sphere have an equal and opposite counterpoint. They work to cancel each other out. However, the earth is not a perfect sphere so there would likely be a gravitational pull towards the area with the greatest mass.
What is the magnitude of gravitational field at earth's center?
If gravity on the surface of Earth is 9.8Nkg, then at the centre it would be 0Nkg
Why Potential energy of an object at the earth's surface is not zero?
It may, or may not, be zero, depending on what you use as the reference level. The absolute amount of potential energy is physically meaningless; what matters is a difference in potential energy between two points.
