When conjoined with Christiaan Huygens' newly discovered law of centrifugal force, it enabled Isaac Newton, Edmund Halley, and perhaps Christopher Wren and Robert Hooke to demonstrate independently that the presumed gravitational attraction between the Sun and its planets decreased with the square of the distance between them.
For når den benyttedes sammen med Christian Huygens' nyligt opdagede lov om centrifugalkraft, gjorde den Isaac Newton, Edmund Halley og måske Christopher Wren og Robert Hooke i stand til uafhængigt at vise, at den antagne tyngdetiltrækning mellem Solen og planeterne aftog med kvadratet på afstanden mellem dem.
