h for the motion of P from ^ to D. The increment or change in thevelocity while P moves from /I to D say is represented by the vector AD(in magnitude and direction). The change in the speed = length OD —length OA. (The hodograph should not be confused with the speed-timecurve. The latter is… … Fig. 259 Fig. 260 1.8 2,0 2.2 2.4Secs.Fig. 261 We are now ready to explain the meaning of rate of change of velocity; webase our explanation on a simple case of curvilinear motion. Suppose that apoint P starts at Q (Fig. 259) and describes the circle shown in such a way thatthe distance traversed…
