Default 3rd Kepler law, twin stars, centres, and semi major axis

Dne 22/02/2016 v 00:46 Peter Riedt napsal(a):


Newton law is low of gravitational interaction,
similarly as the Coulomb law for electrostatic interaction.

Mean what?


That any gravitational interaction obeys it,
in context of non relativistic physics.

All Kepler laws(rules) are direct consequence of the Newton law,
that furthermore is not limited to ellipses.


Newton is a consequence of Kepler's laws. Yes Newton covers inertia.


Exactly the opposite, even if it is younger.

Aside of that,
the 2nd law is consequence of law of angular momentum conservation.
