ent, describingthe line AD; with a greater velocity it will describe acurve nearer to the tangent, as AE; and with a stillgreater velocity it will describe the curve AF. 134. In figure 30, suppose the planet to have passedthe point C with so small a velocity, that the attractionof the sun bends its… … the planet, when at D, is acting in the direction DS,and, on account of the small inclination of DE to DS,the force acting in the line DS helps the planet forwardin the path DE, and thus increases its velocity. In likemanner, the velocity of the planet will be continuallyincreasing as it passes…
