What is Newton's law of gravitational pull?

Answer 1

This is more of a mystery than most people realize. We know that Newton's equations (not really a theory of gravity, but a powerful description of how to measure its effects) work reasonably well in explaining gravitational attraction, and how that attraction weakens with distance. We also know that Einstein's theory of gravity (the bending of space-time in gravitational fields) has withstood many tests. There are still some questions about how gravitation 'propagates' or moves through space. Does it happen instantaneously somehow? Would that violate currently known principles of physics? Does it propagate by way of theorized and undiscovered 'gravity particles'? Does the theorized and undiscovered Higgs Boson have something to do with it, since the Higgs Boson is theorized to be a particle responsible for the 'mass' characteristics of particles?

So, we can explain a lot about the effects of gravity and some things about what we think gravity is, but it is not at all clear or universally accepted just exactly how 'gravitational attraction' actually extends through space.

Answer 2

Newton's law of universal gravitation states that every particle in the universe attracts every other particle with a force that is directly proportional to the product of their masses and inversely proportional to the square of the distance between their centers. This law is expressed by the formula F = G * (m1 * m2) / r^2, where F is the force of attraction, G is the gravitational constant, m1 and m2 are the masses of the two particles, and r is the distance between their centers.

Answer 3

Gravity effects objects in space the same as one Earth; it exerts a force pulling masses together with magnitude Fg= g (m1*m2) / r2 Where Fg is the force due to gravity, g is the universal gravitational constant, m1 and m2 are the masses of the objects, and r is the distance between the two objects' centers of mass.

Answer 4

Conservation of Gravitational Energy keeps objects in orbit. There is a balance between the centripetal (center seeking) force fin= mv^2/r and the centrifugal (center fleeing) force fout= mcv/r cos(angle between radius and velocity).

At this balance cos(Angle) = v/c= Sqrt(GM/rc^2)= z the redshift value.

The mystery of the Redshift is here revealed. The redshift is an indicator of equilibrium , not expansion. Hubble felt the redshift was an "hitherto unknown principle of nature".

The physics community still misunderstands the red shift. The Universe is as Einstein originally envisioned, static, not space expansion. Unfortunately, Einstein's mathematics was inadequate. He added a cosmological constant to account for the static condition. The real answer is that Newton and Einstein should have accounted for the kinetic vector energy due to gravity, mcV. The real gravitional energy is:

E= -GmM/r + mcV = -mu/r + mcV, where V is the vector velocity of mass m.

The energy is quaternion consisting of the real energy -mu/r and the vector energy mcV.

This is how gravity keeps objects in orbit.

Answer 5

The larger the planet, the more of a gravitational pull. The sun's gravity is why the planets in the solar system spin around it, instead of floating away. The earth's gravity is what causes the moon to stay by it

Answer 6

It works by gravity from the sun and the moon

Raven G.

Answer 7

Gravity makes every object in the Universe attract every other object.

Answer 8

Gravity exerts a quantum force on space and bends it directly related to the magnitude of the gravitational force

Answer 9

The same way it works everywhere else.

Answer 10

Gravity twists space-time.
