Gravitation III – Velocity-dependent force

Jorma Rantakivi

The author has completed a university degree with a major in physics and a minor in mathematics. The author has done his life's work in the supervision of nuclear power plants at the Radiation and Nuclear Safety Authority. In addition to the technical work, the author has developed numerical models for thermodynamics, heat transfer, neutron flux calculation and liquid and gas flow calculations. The author has been interested in gravitation and the theory of relativity since his school years. About 10 years ago, the author began to study gravitational theories more intensively and also began to perform calculations based on Newton's and Einstein's theories. The results of the calculations have been reported in books 'Gravitation' and 'Gravitation II' written under the pseudonym U. Kivi and in book 'Gravitation III' written under his own name. In addition, the author has written the book 'Thermodynamics' under the pseudonym U. Kivi.
