Want this question answered?
It is greater at poles than at equator.
Gravity increases from about 9.780 m/s2 at the Equator to about 9.832 m/s2 at the poles. This means an object will weigh about 0.5% more at the poles than at the Equator.
no, but the electromagnetic field of the earth does.
The closer an object gets to the center of the earth, the greater the pull of gravity on that object.
Yes, it is not a constant. The force of gravity is related to the distance from the centre of the earth so that the force of gravity will be slightly reduced at altitudes. Also, the earth is not a perfect sphere - it bulges at the equator and is flatter at the poles. So the force of gravity will be greater at the poles. The force of gravity is also affected by what is under the surface: if standing over dense rocks, the force will be greater. Finally, the force of gravity is also higher after heavy rainfall. [I guess that is because the water fills up all the air gaps in the soil and so increases its density.]
The earth is not a perfect sphere. The spin of the earth causes it to buldge out at the equator, which means the equator is further from the center of the earth then the poles are. The further an object is from the center of mass of another object, the less effect the gravity of those objects will have on each other. So at the equator, an object is being effected less by the gravity of the earth then it is at the poles.
my dear gravity is forever greater than friction and strong atomic force is greater than gravity

Gravity exists wherever there is a body, whatever the mass. The greater the mass, the greater the gravity.
The greater the mass, the greater the force of gravity.
Not only Greater, but GREATEST ! ! !Gravity per unit of mass is a small force.
