Newton's gravity equation F = (G m1 m2)/r2 is verified by Cavendish's experiment using lead spheres that gravitational force is measured using a torsion mechanism which is an extremely crude and inaccurate experiment since Cavendish is measuring a force of one µg. Using m1 = .73 kg , m2 = 158 kg, r = .5 m and G = 6.67384×10−11 , the force between Cavendish lead spheres is calculated F = (6.67384×10−11) x (.73)(158) / (.5)2 ≃ 3 x 10−8 N ≃ 1μ gram which is equivalent to the weight of a single grain of pollen or a single dust particle which proves Newton equation has not been verified by Cavendish's experiment. In an alternative experiment, a lead sphere (2 kg) is suspended using a thin titanium wire (1.5 m), and placed at the center, of the outer surface, of a moveable 2000 kg lead block (fig 12). The angle of the wire is monitored, using two lasers beams. The lead sphere is initially situated .001 mm from the outer surface, near the center, of the lead block, then the lead block is moved away from the suspended lead sphere. After the lead block is moved 1 cm from the suspended lead sphere, there is no measurable change in the angle of the wire, that is suspending the lead sphere, which contradicts Cavendish's experiment and Newton's gravity equation.

Newton's gravity equation was verified even before that by motion of celestial bodies. The Sun gravitational factor G . Msun was determined from it as well. Cavendish experiment was designed to determine G constant, as both masses were known. -- Poutnik ( The Pilgrim, Der Wanderer ) Knowledge makes great men humble, but small men arrogant.

And the corresponding equation is F = G m₁ m₂∕r² or F = G m_1 m_2∕r^2 instead (parentheses are optional). While it is not necessary to use the proper Unicode characters, it *is* necessary to write subscripts *differently* than superscripts, especially if the latter are *exponents*; here, it is necessary to make the force F that the two bodies, with masses m₁ and m₂ respectively, exert on each other inversely proportional to the *square* of the distance r between their centers.

"History shows us examples of scientists who were able to make a great leap forward specifically because they were not limited by the data. One of the most dramatic examples occurs at the beginning of the nineteenth century, when we may find a scientist willing to ignore the limitations of numerical facts for the sake of correct idea or theory, even to the extent of saying that certain numbers probably should be made a little bit bigger, others a little smaller, and so on. It was precisely in this way that Dalton proceeded in developing his atomic theory. Some scientists do not like examples of this sort, because they imply a special virtue "fudging" the evidence or "cooking" the data, and they warn us that we must not ever tell our science students that discoveries have been made in this way." (Suppe, 300-301).

"The German philosopher Gottfried Wilhelm Leibniz was among Newton's sharpest critics in this respect. He objected that the conclusion that every body is attracted to every other body by a gravitational force was not 'deduced from the phenomena' as Newton had claimed." (Gower, p. 72). Prove that Newton's gravity equation is true using small objects (less than 200 kg)

Newton's gravity equation F = (G m1 m2)/r2 is verified by Cavendish using lead spheres that gravitational force is measured using a torsion mechanism which is an extremely crude and inaccurate experiment since Cavendish is measuring a force of F = (6.67384×10−11) x (.73)(158) / (.5)2 ≃ 3 x 10−8 N ≃ 1μ gram which equivalent to a single dust particle. In an experiment, a lead sphere (73 kg) is suspended using a thin titanium wire (1 mm), and a single strain, of a down feather, is brush against the suspended sphere which is approximately equivalent to a 1μ gram force. No motion of the suspended sphere is experimentally observed, during and after the interaction which is monitored using a small mirror place on the sphere and a laser beam reflected from the mirror, at right angles, onto a screen, which is experimental proof Cavendish's experiment is an experimental ruse. Cavendish's force is within the range of the measurement error of the experiment. This method of deception is also used in Roemer's measurement of the velocity of light.

Newton was extremely insecure. He would have been famous with his F = ma equation and subsequently equations of motion but his equations of motions were based on L derivative and that hurt his feeling which it should not have if he were a man but unfortunately Newton was not. Henceforth, he stole the gravity equation from some one and stuck his name to it but that what lesser physicits do such as Kirchhoff and his formulation of Huygens' principle to dispel the retrogressive wave by mathematically proving a spherical wave is not a spherical wave to eliminate the unwanted structure of the retrogressive wave.

"The Cavendish experiment is repeated in physics classrooms around the world:" Gary Harnagel 4/17/2016 4:46 AM To record the force of 1μ gram requires the motion of the .73 kg lead sphere that is suspended from an iron rod but the motion of the .73 suspended lead sphere cannot be produce when applying a 1μ gram force which is equivalent to a single dust particle. Try this, suspend a .73 kg lead sphere using a thin wire and brush a feather against the lead sphere and tell me if you detect a motion of the suspended sphere.

instead (parentheses are optional). While it is not necessary to use the proper Unicode characters, it *is* necessary to write subscripts *differently* than superscripts, especially if the latter are *exponents*; here, it is necessary to make the force F that the two bodies, with masses m₁ and m₂ respectively, exert on each other inversely proportional to the *square* of the distance r between their centers. ----------------------------------------------------- Great argument! I couldn't do better. Here something better. You should have used f instead of F for the force since f come before g in the alphabet.
