DOUBLE FORCES OF ATTRACTIVE GRAVITATION PARADOX II

From a classic text on mechanics:

￼

When science teachers are asked how does gravity work, they answer in this manner:

Gravity is a force.

Gravity is directed towards the center of the orbit i.e. the sun.

That makes gravity the centripetal force.

no the out word circular motion is the centripetal force, gravity is the string holding the ball in.

Imagine a ball attached to a string and you are holding the other end of the string and moving your hand in such a way that the ball is in circular motion.

Then tension in the string is centripetal force.

not quite, is the results of inertia of the earth and gravity

Now, ball = earth

you = sun

tension in the string = gravity

Gravity is the reason one object orbits another. An analogy is swinging a ball on a string over your head. The string is like gravity, and it keeps the ball in orbit. If you let go of the string, the ball flies away from you. (Dr. Eric Christian, April 2011)

yes

Centrifugal force acts on a rotating object in a direction opposite the axis of rotation. Imagine that you have a tennis ball tied to a string. If you swing the tennis ball on the string around in a circle, you would feel the ball tugging on the string. That is the centrifugal force on the ball. It is counteracted by tension in the string that you are holding. In this example, the tension force in the string is like the gravitational force between the earth and the sun. The ball doesn't get closer or farther from your hand. If you suddenly cut the string, the ball would go flying away, but that wont happen to the earth because of the sun's gravity.

yes

Forces can make something move or stop something from moving. For a planet in orbit around the sun, the string is invisible. That invisible string is the gravitational force between the Earth and the sun.

yes

Then, the Mass Attraction and General Relativity Attraction concepts are not viable models for the cause of gravity and inertia.

why?

Applying any "attractive" force model to the Earth Moon dynamic forces, we obtain this system:

The Earth’s attractive gravitation balances the orbital centrifugal force of the Moon.

The Moon’s attractive gravitation balances the orbital centrifugal force of the Earth.

the same force not two, from a from different point of view.

At first this may seem like an orderly and balanced attractive force system; however,... the following paradox exists. If the seat, source and cause of the "apparent" attraction forces are "internal" to each of the bodies...the attraction concept produces twice the force that is necessary to balance the centrifugal orbital forces of a planet moon system. The concept of "attraction" between bodies requires that the force “from” each separate body acts on the remote body,-- and equally on the originating body. Another example of a balanced system is a rope under tension; each end has an equal amount of opposing force. As noted by Newton's third law of motion, " To every action there is always an opposed equal reaction".

This double force paradox is directly applicable to the "mass attraction",... the General Relativity “attraction” and all other attraction type concepts of gravity.

This example may help visualize the double force issue.

Let there be two rafts ( x and y ) freely floating on a clear calm lake with a rope between them.

Both rafts are still and are a rope length apart.

The man on (raft x) pulls on the rope which is attached to raft y.

Raft x will move toward raft y,… and raft y will move toward raft x.

Both rafts will receive equal and opposite force and motion.

It is not possible for (raft x) to remain still and be the source of the force.

I see no doubling divorces of forces

The Mass Attraction Models of Gravitation

The attraction concepts accept Newton's inverse square equation of gravity's force between two bodies as:

F = G x (M1 x M2) / r squared .

The surface gravity (g) for each of the bodies can be derived from the gravitational constant (G) and the mass and radius of the bodies. Using Newton's equation the g forces, allegedly "seated" in each of the "two" bodies acting on the other at a distance, can be calculated.

Within the "attraction" concepts:

From Earth, the concept requires that Earth's gravity is attracting the Moon; and an equal Earth anchored “attraction” force is pulling the Earth toward the Moon.

From the Moon, the Moon's gravity is attracting the Earth; and this Moon seated force is equally pulling the Moon toward the Earth.

there is no doubling forces, only the point of reference is changing

Using: 1 ) Newton’s equation as given above, 2 ) basic arithmetic, 3 ) common logic and 4 ) the mechanics of force, it is shown that the assumed Earth and Moon seated forces are equal; and as a result;…"all attraction models" produce twice the force that is required to balance the centrifugal forces of orbit!

why? : no Dublin of forces occur

The General Relativity Model of Gravitation

The exact same paradox arises with the General Relativity (GR) concept of gravity. It postulates that Mass warps a hypothetical "fabric of spacetime" and the warped fabric of spacetime causes “attraction” of other masses. Since in the GR theory the seat of the attractive force is anchored within the center of the planet’s and moon’s positions, we would again have twice the force required to balance the orbital forces of the Earth Moon system.

why? : you are seeing twice, where there is no twice; no Dublin of forces occur

It is the same force, just viewed from a different pointe of view.

It's hard, you almost have it, but then you jump to the wrong conclusion,

And won't let go.
