text: But the time is proportional to PQ divided by the velocity v, and in the limit as Q approaches P, PQ approaches PR, so that t2 becomes equal to PR2/v2.
text: The central force at P is again proportional to the displacement from the tangent QR over a short increment of time divided by the square of this time; but now the time is proportional not to the arc PQ, but to the area swept out, which in the limit as Q approaches P, is the triangular area SPxQT/2.
