what is the origin of the gravitational force?

Question

scientist are saying that every thing in the world is attaracted by gravitational force but from where this foce come/

Answer 1

The actual origin of gravity is still a mystery to physicists. Yes, everything with mass has gravity, but that doesn't explain where it actually comes from. The current hypothesis is that gravity originates from a hypothetical particle called the "Higgs boson", which hasn't yet been observed. Physicists hope that the Large Hadron Collider at CERN (Switzerland) will be able to detect it soon.

Answer 2

Every point mass attracts every other point mass by a force directed along the line connecting the two. This force is proportional to the product of the masses and inversely proportional to the square of the distance between them:

F is the magnitude of the (repulsive) gravitational force between the two point masses
G is the gravitational constant
m1 is the mass of the first point mass
m2 is the mass of the second point mass
r is the distance between the two point masses


Assuming SI units, F is measured in newtons (N), m1 and m2 in kilograms (kg), r in metres (m), and the constant G is approximately equal to 6.67 × 10−11 N m2 kg−2 (newtons times metres squared per kilogram squared).

It can be seen that the repulsive force F is always negative, which means that the net attractive force is positive. (This sign convention is adopted in order to be consistent with Coulomb's Law, where a positive force means repulsion between two charges.)

Answer 3

This is true that every thing on earth is attracted by gravitational force.This force comes from the earth itself,from the inner part of the earth.As it is said that if there is a hole in the earth from one side to the other passing from the centre and we drop a ball in the hole it will settle at the central point,where push and pull will be equal.

Answer 4

Mass takes space.Space wants it back.So space presses the mass That creates the gravitational force.
I read it in Yahoo answers,and I want to congratulate the first who wrote it.It is the most clever thing I read recently

Answer 5

from the earth greatest to the core.
this gravity held all together the mantle and crust. that every moving object is subject to enery that is influenced by gravitational pull. it plays the greatest part of science. wthout it every enery is imbalance. and there is no physical properties it will only be uncertain. mass will be absolute but weight not.
the greater the gravitational pull the densest s the object. just compare jupiter and earth, earth is so small but t is the hardest compared to jupiter, because of our gravitational force s greater. we are likely to attract object like meteors and comets. coz we are the magnet for gravity.

Answer 6

Every object on Earth is trying to go towards the largest mass. Since the Earth is so huge, it has a huge gravitational field, thus objects go towards it.
