Physics, Astronomy & Cosmology / How does one calculate velocity when using spherical coordinates?
« on: 26/09/2016 02:37:28 »
Hi,
I have a little doubt. I have, refered to the Sun, the cartesian positions and velocities of an asteroid (in x, y and z coordinates - 6 values in 3D dimensional space). I can easely calculate the polar coordinates (longitude and latitude - along with distance). My doubt is: how do I calculate the longitude and latitude speed in degrees/radians given the cartesian values? Is it the same way? I'm sorry for this stupid doubt....
Kind regards,
Kepler
