I Trajectories, equation of motion and forces...

  1. Mar 20, 2016 #1
    Setting a cartesian system how can i get the equation of the trajectory of an object knowing the forces acting on that object?

    Example: If F= GMm/r^2 and let be the sun at the center (point (0,0,0)) of the cartesian system how do i get the equation of an ellipse in this system? ( x^2/a^2 + y^2/b^2 = 1)

    Where x and y define the position of the planet in the chosen system centred in the sun
