Because there is no range limit on the gravitational force, the gravitational force of the earth is only zero in the exact centre of the earth, where it cancels itself out.

Realistically, the force is so small outside the immediate vicinity of earth, that it may as well be zero.

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.


Why at the center of the earth the gravitational force is zero?

if four horses with equal power are pulling one from opposite sides, it will not move. means net force would be zero. same is at center of earth. the mass of earth around center attracts equally to all sides( because geometrical center and center of mass are same). so net force is zero. On the other hand if you think of gravity as a force puling you into the centre of the earth then when you are at the center of the earth gravity must be zeero


In one complete orbit is the work done by the earth on the space station positive negative or zero?

The work done by the Earth on the space station over one complete orbit is zero because the gravitational force is conservative. This means that the work done in moving an object over any closed path is zero.


What work is done in one complete orbit by the earth on a space station that orbits the earth at 375 km above the earth positive?

The work done by the Earth on the space station is zero since the force of gravity is perpendicular to the motion of the space station. This means that there is no displacement in the direction of the force, and thus no work is done.


How is the force of earths gravity overcome when an object is launched into space?

When on Earth, you can escape if you move away from the Earth at the "escape" speed. Gravity will slow you down and you will reach zero speed at an infinite distance.

At what height from the earth the weight of an object become half of the weight on earth?

The weight of an object becomes half at a height where the gravitational force is half of the force on Earth, about 3,578 km above Earth's surface. At this height, the object and Earth are attracted with equal and opposite force.

What happens if g force is zero on earth?

There will be no gravity. Objects will start floating.


Could the net force ever be zero?

Not ever on earth or somewhere with gravity


How do you create zero gravitational force on earth?

Gravitation can't be cancelled or shielded. You can have the appearance of zero gravitational force when you are in free fall. Without going into outer space, this can be maintained for a few seconds at most.


What is weight of earth?

AS WE KNOW, that there is the force of gravity at the center of Earth, if every part or portion of earth has its weight then net weight of the earth will be zero........


Why does not this force lift you the earth upward?

The upward force balances exactly you weight so the resultant force is zero and you stay on the ground, fortunately!


Is it true an astronaunt is weightless in space?

It is logicaly true but not scientifically because if we refer to it according to science then it is the gravitation that has become zero, the same gravitational force due to which our weight is present on earth.


What is the value of 'g' at center of earth?

The value of acceleration due to gravity 'g' at the center of the Earth is theoretically zero because the mass of the Earth surrounds an object equally in all directions, resulting in a net gravitational force of zero at the center.


Why deflection of wind become zero at the poles?

At the poles, the Coriolis force is minimal, causing the wind to be less affected by its deflective influence. The Coriolis force is based on the rotation of the Earth and is strongest at the equator, gradually weakening towards the poles. As a result, wind deflection decreases towards the poles and becomes nearly zero.


When an objects net force is zero is it accerlerating?

When an objects net force is zero, its acceleration is zero. No force , no acceleration.
