### Rutherford model - Wikipedia

The Rutherford model was devised by the New Zealand-born physicist Ernest Rutherford to describe an atom.Rutherford directed the Geiger-Marsden experiment in 1909, which suggested, upon Rutherford's 1911 analysis, that J. J. Thomson's plum pudding model of the atom was incorrect. Rutherford's new model for the atom, based on the experimental results, contained new features of a relatively ...

### Simulating Planetary Orbits — 50 Examples 1.0 documentation

where G is the gravitational constant, m_1 and m_2 are the masses of the two objects, and d is the distance between them. In SI units, G has the value 6.67428 \times 10^{-11} N(m/kg)^2, so d is measured in meters, the masses are measured in kilograms, and the resulting F is in newtons.
