What is the law of gravity?

Answer 1

There are 4 fundamental forces in nature: Gravity, electromagnetic, and the strong and weak nuclear forces. It is postulated that these 4 forces can converge into 1 super force, whose equation governs all. However, gravity is giving physicists the biggest trouble in discovering such a convergence. Gravity and electromagnetism share almost the exact same equation, except for a difference in a constant.

Also, there are other laws in nature that do not deal with forces, but rather concepts. These may include the 1st and 2nd law of thermodynamics, the law of conservation of energy, the law of conservation of momentum, and many, many more.

The most peculiar to me is the law of conservation of mass and energy. This states that the mass and energy in any closed system is always constant. Let the universe be this closed system, and in other words, mass and energy are never destroyed, only transformed!!! Think about the billions of stars, and the billions of planets, inside the billions of galaxies, that contains all of the tremendous amounts of energy in each star, and just before the big bang, this was one tiny, point object of near infinite mass and infinite energy! One point in space, smaller than a spec of dust, blew apart and created all of the things you see today in the universe, as well as provided all of the energy! Amazing.

Answer 2

The law of gravity is:

E = -mMG/r + mcv = -mu/r + mcv

This energy formula consists of real energy Er = -mMG/r and vector energy Ev = mcv.

Newton's law of gravity can be derived from the real energy Er = -mMG/r, by taking the derivative of the real energy to get the force F = mMG/r2

Newton's law of gravity is a force law that defines the force of attraction between masses. Newton's law of gravity is, however, incomplete. Newton's force law is for the centripetal, or attractive, force of gravity, but does not define the centrifugal, or repulsive, force F = mc∇v = (-cv/r)cos(vr), due to the vector derivative of the vector gravitational energy. The vector energy is also the result of gravity in that the velocity v = √(GM/r).

The force law of gravity is:

F = (d/dr + ∇)(-mu/r + mcv) = m(u/r2 - c∇v) + m(dcv/dr + c∇xv - ∇u/r).

The equilibrium condition occurs when the force F equals zero. This gives the boundary condition of energy and the continuity condition of energy.

0 = m(u/r2 - c∇.v) + m(dcv/dr + c∇xv - ∇u/r).

Here, the centripetal force equals the centrifugal force:

mv2/r = (mcv/r)cos(vr) and 0 = m(dcv/dr + c∇xv - ∇u/r).

The law of gravity shows that conservation of energy is the basis of equilibrium. Newton's and Einstein's laws of physics are incomplete in neglecting the vector energy mcv in their gravity laws. Einstein's curvature theory is also incorrect. The deflection of light is not due to space curvature but plain old gravitational attraction, tan x = 1/2gt2/r, where g is the gravity of Earth and r is the distance from the sun and t = r/c.

Answer 3

The law of gravity states that all objects with mass are attracted to each other. The force of gravity between two objects depends on their masses and the distance between them. It was first described by Sir Isaac newton in the 17th century.
