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.
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.
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
It works by gravity from the sun and the moon

Gravity makes every object in the Universe attract every other object.
Gravity exerts a quantum force on space and bends it directly related to the magnitude of the gravitational force
The same way it works everywhere else.
Gravity twists space-time.
Newton meter
The gravitational constant on Earth is 10 Newtons per kg (well exactly about 9.81 Newtons)
uranus's gravitational pull is 91% or earth's.
Its a matter of being scientifically rigorous. You can not claim the 2nd law as a law unless you first establish the first law.
i dont now
Less than one tenth (1/10) of the earths gravitational pull.
It is associated with the law of gravitational pull.
Gravitational pull
Coulomb's Law
Gravitational pull is a force and is measured in Newtons, the unit of force.
Isaac Newtons great Discovery was when an apple fell on his head and he realised that it had fallen because of Gravitational pull.
Newtons are the force one object exerts on another. The weight you see on a bathroom scale is how much the scale pushes back, which equals the Newtonian force. However, mass and Newtons are different but related. Newtons is the gravitational pull multiplied by the mass. The basic equation is: (mass in grams)(9.8)=Force in Newtons 9.8 is the gravitational pull on every object on Earth.
newtons gravitational law is similar to that of coulomb's law...
An Apple fell on Issac Newtons head from an apple tree, and he wondered why it happened, so he conducted a load of experiments and collected evidence that pointed to the theory of gravitational pull
No Gravitational potential energy equals no force and thus no acceleration.
Gravitational pull is measured in m/s (meters per second). For example, Earth's gravitational pull is 9.8 m/s/s, or 32 feet per second per second. Weight is similar to gravity, as weight is the measure of the gravitational pull upon an object. This force is measured in Newtons.
Thats f (newtons) = (G * m1 * m2) / d2 where: G = newtons gravitational constant m1 = mass, object 1 m2 = mass, object 2 d = distance between
