somes explanations ?

Hi Let a classical particle with unit mass subjected to a radial potential V and moving in a plane. The Hamiltonian is written using polar coordinates (r,\phi) H(r,\phi) = \frac{1}{2}(\dot{r}^2+r^2\dot{\phi}^2) - V(r) I consider the angular momentum modulus C=r^2\dot{\phi}, and I...

Hi Let's consider the three body problem. The motion of all bodies is a manifold of dim 18. But I will consider that the mass of the third body is neglictible and I am interested in the motion of the third body (in the case, this is the restricted three body problem (non necessary planar nor...

Thanks for your explanations, they are very useful ;)

Hello I would like to understand the resonance phenomenon that can occurs when we deals with satellite's orbits. Here what it is said about it : KAULA - Theory of satellite geodesy - p. 49...

Hi Geopotential U is the gravitational potential of the Earth without taking into account the rotation of the Earth whereas gravity's potential ##U_T## considers the rotation of the Earth such as : ##U_T = U + \frac{1}{2}\omega ^2r^2cos(\psi)^2## (with common spherical coordinates)...
