B Kepler's law of areas

  1. Dec 13, 2016 #1
    Hi,

    Just wanted to know how can we attribute the kepler's law of areas to a radially directed force?

    The law of areas amounts to a statement that the angular momentum of a satellite about a central point is conserved. If there were an off-center force, that would amount to a torque and angular momentum would not be conserved.

    I think you may need to elaborate on the question.
